Processing of scrap of non-ferrous metals. Own business: scrap metal processing. Necessary equipment for scrap metal processing and a list of documents to start. Start with little financial outlay
Metallurgy is one of the largest and developing industries. The issue of recycling of various scrap metals is very topical and acute. In modern industry, there are several methods for processing secondary raw materials, but leading industry experts are still looking for new, innovative ways, since this area is very important and financially beneficial for the country.
Non-ferrous metals in which we specialize
They are not magnetic and tend to have greater corrosion resistance than ferrous metals. Due to its widespread use, non-ferrous scrap metal is commonly recycled. The secondary materials in scrap metal are vital to the steel industry, a science that focuses on the study of physical and chemical properties metals. Non-ferrous metal scrap comes from industrial scrap metal, particulate emissions and legacy technologies such as copper cables. Precious colored materials usually come from jewelry, electronics and industrial catalysts.
Advantages of recycled materials
There are a number of advantages and main uses for scrap:
- The material is needed when melting the metal, while reducing the level of costs;
- Recycling and recycling of raw materials has a positive effect on production natural resources, as the need for them is reduced and there is a saving of minerals, as well as labor and economic reserves.
Processing technology
Pre-scrap metal is carefully sorted into types and categories, of which there are several. In general, raw materials are divided into non-ferrous and black scrap, since they have completely different physical and technical characteristics and it is impossible to put them into one process of technological processing.
Some of the scrap metal we specialize in include. When it comes to non-ferrous metal recycling, we have various methods and mechanisms to sort and produce quality recycled material, which is prepared for feeding furnaces and smelters so that it can be processed into new products.

After sorting, the scrap metal is subjected to cutting and cutting. Then they are analyzed for the presence of carbon components in the material and the content of alloying elements. The material is sorted according to quality indicators, there are 28 in total.
Separately distribute scrap of ferrous metal and cast iron. Black raw materials include:
Metals are part of our Everyday life, are used to produce cars, trucks, trains, trains, ships, planes, white items, cutlery, pots and pans. Metal is divided into two categories: black and non-ferrous. Ferrous metals contain steel and iron, aluminum, copper and brass are examples of non-ferrous metals. Steel is 100% recyclable and is the most recycled material per ton in the world. Sorting ferrous metals from non-ferrous metals is much easier and cheaper than sorting various plastics due to the magnetic properties of steels.
- Metal shavings;
- Waste from foundry production;
- Waste metal;
- Scrap metal generated as a result of household activities.
Scrap iron can be both in the form of shavings and as waste from foundry work. Before the material can be processed, it must be collected, the acceptance of scrap plays a huge role here. A large amount of ferrous scrap goes to steel casting, where raw materials are mixed with cast iron. After sorting and cutting, the metal melts, this can happen both on the territory of the enterprise and outside it.
Metal Recycling Process
The metal recycling process includes four stages. The metal is collected where it is sorted into bins. Any non-ferrous metal products that have a steel or iron component are treated as scrap metal. The scrap metal centers then sell the scrap metal to large supercombiners, where it is crushed and then melted down in furnaces at high temperatures for the production of blocks, ingots or sheets, which will be sold to manufacturers of metal products. Following is the metal recycling process.
Recycling of non-ferrous scrap metal
The process associated with non-ferrous metal is much more complicated, since sorting occurs for each type separately. There are several groups of non-ferrous metals:
- Lungs: sodium, aluminum and others;
- Noble, for example, gold;
- d-metals: titanium, vanadium and others;
- f-metals;
- radioactive;
- Basic: copper, zinc and others.
A special role is played by lead, which is found in large quantities in batteries. This is due to the fact that it is batteries that are mostly recycled.
Collection and sorting The first stage of metal recycling is the collection of all metal products. The inhabitants of Adelaide bring many metal objects. Commonly recycled items include white items, radiators, steel or alloy wheels, roller shutters, bicycles and batteries, even a stainless steel sink can be recycled. Metal products are sorted into trash passes, ready to be transported to scrap metal supercomputers for recycling. are high due to the demand for scrap metal that has been recycled. Crushing and Grinding Scrap metal recycling plants first crush the metal in rollers so it is easier to process on conveyor belts. Separation The shredded metal is then placed in magnetic drums which separate the ferrous and non-ferrous metals. Non-metal materials such as paint or plastic are removed by blowing hot air through the pulverized metal, sucking in impurities like a vacuum. Melting and cleaning. The next step is to melt down various scrap metal in large furnaces. Each metal has a specially designed furnace depending on its properties. The ovens have fuel-efficient regenerative burners to reduce the amount of energy used and the environmental impact. They are also equipped with jet agitators to ensure uniform temperature and composition, facilitating the circulation of metals in the furnaces. The mixing process guarantees the highest quality end product. In the molten state, the metals are further refined by "eddy current" electrolysis before being poured into different shapes; depending on the metal and cooling. Hammer mills then pound the metal into hand-sized chunks. . Large aluminum ingots; weighing up to 18 tons and containing about 5 million used cans, are sent to mills where they are rolled into sheets and then bought by aluminum can manufacturers to put into new cans.
Recycling of non-ferrous metal scrap has become a priority for the development of the industry, which replaces the process of extracting natural resources, which is very expensive.
Enterprises seriously engaged in this activity must have storage facilities, press plants, separators and other equipment that is necessary for a high-quality scrap processing process.
Despite the energy costs involved in the recycling of scrap metal, the energy required in this case is less than in the production of raw materials. Making steel from recycled cans, for example, uses 75% less energy than making steel from raw materials.

Scrap metal recycling principles
It should be noted that secondary raw materials are the most necessary element in the smelting of metal; through the use of recycled metal scrap, there is a significant reduction in the cost of the entire production. Savings are visible in everything, and in the cost of charge type material and energy costs, and much more. In addition, the processing and recycling of scrap metal, both non-ferrous and ferrous, reduces the burden on the use of natural resources in this area, especially since they are already quite depleted today. All of these factors listed above are a significant argument in.
The global market for recovered mixed metals continues to expand. There are commercial opportunities to use this oft-forgotten material. Other non-ferrous metals found in Zorba include copper, lead, brass, magnesium, nickel, tin, and zinc in elemental or alloyed form. Stainless steel is usually only present in small quantities because, depending on the grade of the material, vortex separators usually cannot remove it from the product.
On a global scale, industrial production in all areas of modern life creates a huge demand for non-ferrous metals that are commonly found in Zorba - in particular, copper, nickel and brass. The potential market for these valuable fractions can be seen all around us in the products we use every day. The use of electronic products is now so prevalent in all areas of life that there is a huge demand for non-ferrous metals for use in manufacturing. As an example, the global requirement for copper to be used for airborne electrical systems only in cars, is 5 million tons per year, which corresponds to about 10% of the world's production of copper ore.
As a rule, the most frequent is the processing of ferrous scrap. This is due to the fact that today steel is produced in large quantities, the technological process of casting of which requires sufficient a large number of scrap metal for mixing it with cast iron. At the same time, it should be noted that the peculiarity of this technological process is that the more scrap is used in smelting, the better the quality of the finished product, in this case steel, will be.
Currently, a significant proportion of the total resources used in manufacturing is achieved through the use of recycled metal components - a trend that is growing. Recycling aluminum scrap is also extremely beneficial - up to 95% of energy costs can be saved compared to the labor-intensive extraction of a more costly primary resource. At the same time, global demand for aluminum is steadily increasing in markets such as automobile manufacturing due to its lightweight properties.
As a result, it makes commercial and economic sense to use high quality recycled materials instead of a fraction of virgin materials. In response to this strong market demand, recycling of non-ferrous metals from end-of-life shredded equipment such as automobiles and household appliances is steadily increasing as many raw materials such as copper or aluminum are recovered in this way.
Technological processes of scrap metal processing
The basis of pre-processing of scrap metal includes processes such as sorting, in which metal is separated into categories and varieties. Today there are several categories of scrap metal. Firstly, this is the separation of non-ferrous and ferrous scrap, since they cannot be used in one technological process.
What is handed over for processing of scrap of ferrous metals?
However, market competition dictates that these fractions must be able to be extracted to a higher purity than ever before, with refined individual non-ferrous fractions significantly higher than those of unsorted iron mixtures.

General technologies. Manual sorting or copying of auto-complete fractions is a costly process in industrialized countries with a natural lower limit in terms of material recovery. Smaller metal parts under 20mm and wires cannot be sorted easily or, if present, require a lot of time and effort. Optically indistinguishable metals cannot be sorted out and are therefore lost.
The next stage of processing is cutting and cutting of scrap metal. Next, scrap metal is sorted out according to the content of carbon substances in it, according to the content of the alloying composition, according to its quality indicators, which today there are about twenty-eight types.
Ferrous metal scrap and cast iron scrap are also distributed. The first type of scrap includes such groups as shavings, as well as metal, which is a waste from the foundry industry, and scrap metal, which is formed as a result of domestic use and waste material. industrial production. The next type is cast iron scrap, which can also be in the form of shavings and foundry waste.
For example, it is not easy to manually identify and separate small pieces of various grades of aluminum and metals, as well as to detect zinc or steel samples encapsulated in aluminum. There is also the problem that color grading is nearly impossible for identical non-ferrous materials such as gray-metals of aluminum alloys, zinc and lead.
Scrap processing and factories carrying out such work
Evenly floating processes, also known as dense media, are used to separate metals with different densities, such as separating aluminum from other non-ferrous metals. This process requires large amounts of water and other additives, the processing and disposal of which is an additional burden on the environment.
Another type is a type of scrap metal such as stainless steel scrap. This group includes metal processing waste and used materials that are out of order.
Recycling of non-ferrous scrap metal
Recycling of scrap metal is one of the most important areas in the metal industry; today this activity is referred to only as recycling. Scrap metal recycling activities affect absolutely all segments of the population.
Scrap metal recycling principles
In terms of performance, the immersion-float method can only separate materials with different densities, while materials such as the valuable mixture of heavy metals from copper, brass, zinc and other heavy metals present an insoluble problem for this method, since they have similar density. In addition, as floating point immersion processes usually use water-based media that move with the current, there is a risk that light materials, as well as materials with a large surface area, will be captured by the current and placed in the wrong fractions.
Recycling of non-ferrous scrap metal is a more complex process and is carried out separately for each type of non-ferrous metal. As a rule, it is most often used in which there is a sufficiently large amount of lead. This metal can be successfully used for further purposes, and is easily recycled. The same is the case with products containing mercury, as well as with scrap of precious metals.
