one of the important products in the steel industry is iron and metal scrap. Of course because of their qualities they are priced per kg or ton. One of the important construction wastes with great material value is metal scrap, the purchase and sale of which is particularly important on the market, and the product is sorted according to place and time of production. One of the most important sources of raw material supply for steel products is scrap or ferrous scrap. Simply put, materials that can be recycled are called waste. Unlike other scrap metals and iron, scrap has monetary value and is returned to the production cycle. Depending on the production method, the alloy used and its purpose, the type of waste is different, this problem can lead to different recycling methods and, of course, the waste prices will vary for different types of products. Construction waste is divided into several categories, some of which, such as crushed bricks and blocks, must be transported or disposed of. Another type that can be recycled is iron, copper, aluminum and cast iron scrap. 
In fact, the waste left behind by the construction, demolition and reconstruction of buildings in unwanted and unexpected ways is known as construction waste. About 10-15% of the total materials used in buildings are non-metallic waste such as bricks, concrete, wood and plastics. On the other hand, some waste such as scrap metal, copper, aluminum and cast iron can be recycled. This makes some people more willing to buy all kinds of junk. Scrap metal is not only obtained by destroying a set, but due to the aging of household equipment, newer equipment may eventually need to be replaced. Waste: The wastes produced by the raw materials and residues left after the iron plate is cut are said to be non-recyclable wastes. Waste: Waste is generally discarded material that is primarily used as raw material for the manufacture of parts and other products. Source of waste:
- purchased waste
- waste return line
- Scrap types by production time
- Scrap from raw materials and steel is divided into two categories:
Internal scrap: This type of scrap is generated at various stages of steelmaking, such as the manufacture of ingots and steel products, and is actually generated when the product does not meet the quality standards. External scrap: This type of scrap is generated outside the production stage and is divided into two groups, old and new. The new industrial waste is produced by the final steel producers. The quality of these scraps is well known and most of them are products from the rolling stage, including wire rods, scrap plate, and chips produced by industrial units. The used industrial waste includes steel products that have reached the end of their useful life, including scrapped cars, building components, bridges, and construction equipment. Scrap usually has several grades, where grades come from light and heavy engine parts, including oily, black and stainless plates, and grades are usually window and door scraps, bicycle panniers, etc. Tertiary waste is often rusty and contains elements such as chromium, nickel and alloys. Standards associations and industrial research organizations apply special criteria for all scrap, after which scrap is separated from each other. Various scrap metal Ultra special special waste Types of ultra-special waste have no place in the Iranian Institute of Standards and Industry. In other words, people who work in the waste field put high-quality scrap in a special category and rate their price value higher than other types. Galvanized iron filings Galvanized iron is highly resistant to corrosion due to its zinc coating. However, if the galvanized iron sheet is deformed due to breakage or high stress, or does not reach the expected quality during the production process, it becomes scrap. The presence of zinc in this scrap gives it a lower grade than other scrap and a lower price. car smash Car waste is completely pressed after burning substances and plastic pieces, called pressed waste. Most of this waste is used in large aperture arc furnaces. Tin scrap In today's market, tin shavings are sold in two forms: pure tin and bulk tin. All cans used to store food and solid oil etc. are considered Aleppo waste. 
iron metal price per kg
The price of metals like iron is in kg or tons, simply because of the properties of the metal. The metal itself is of course also important, because metals such as gold or platinum are not priced that way. Iron ore is an ore containing iron metal. The chemical symbol for iron is Fe. Iron ore is extracted from iron ore. The appearance and internal structure of iron ore vary from mine to mine. Iron ore consists of a number of different minerals, but the most important are magnetite and hematite. Types of iron ore by mineral type:
- Hematite
- magnetite
- Zeolite
- Limonite
- siderite
Types of iron ore from the appearance:
- blocked
- granular
- concentrated
- particles
Iron ore is the most important raw material for the production of steel. In general, iron ore is mostly used in traditional steel production methods (blast furnace/converter) and only a small part is used in other methods, especially direct recovery, so of the total iron ore mined in the world, less than 10% is used for direct regeneration and more than 90% is used for the blast furnace. The required specifications for iron ore vary according to the type of consumption and the region where it is produced and delivered. For example, iron ore that works well in traditional methods may not be available in any way in direct recovery methods, or the specifications required to use red clay for coloring are completely different from its metallurgical application. It follows that not only does the size of iron ore required for different applications vary, but in different locations, even with any blast furnace or direct regeneration method, the size of the iron ore must match the type, capacity, height, etc. of the furnace. The production of steel from iron ore usually takes place in one of the following ways:
Granular iron ore
Today, granular iron ore is used less. The reason for this can be explained by its low reproducibility. In any case, for iron ore to be used directly for the production of iron, its size must be clearly defined.
lump of iron ore
The lump is the most common way to use iron ore. The steelmaking industry produces and consumes approximately 700 million tons of ingots each year. 
Iron ore in pellet form
At present, the annual production of pellets is about 300 million tons, of which more than 80% is used in blast furnaces and the rest is used for direct regeneration. Obviously, the specifications of the particles used in each method are different. As previously mentioned, iron accounts for 5% of the weight of the earth's crust and is the fourth most abundant element in the world after oxygen, silicon and aluminum. It melts at a temperature of 1538 degrees Celsius (2800 degrees Fahrenheit). Iron ore is malleable and can be easily shaped by hammering. Iron ore is rarely used without the addition of other elements and is often accompanied by additives to improve its properties. Carbon ferroalloys are mainly used in steelmaking and can add about 0.003 to 8% carbon. They are divided into low carbon steel, medium carbon steel, and high carbon steel. In the steel's carbon content, there is iron carbide (Fe3C), also known as hemi-ironite. Iron's different mechanical properties are achieved by varying the amount of carbon. High carbon iron becomes cast iron and low carbon becomes cementite and ferrite. This versatility of iron and carbon alloys makes them widely used in engineering and makes them the most important industrial metals.
iron scrap price per kg
In general, the recyclable materials discarded by industry, the automotive industry, and residential areas are called scrap iron, and the price is calculated per kg, and the recycling is the material that has been prepared for recycling.
scrap iron
Defective products and useless cast iron and steel scrap are called scrap. One of the main sources of metals for arc furnaces is scrap, which is called scrap iron, in other words, the material that can be recycled is called scrap, generally, the material that is discarded in the construction industry or even in cars. Products that can be recycled are part of the waste. Unlike waste, waste has a significant monetary value. Especially scrap metal and scrap iron. Scrap or iron scrap refers to mild steel.
source of scrap iron
Products that do not meet production standards are used as raw materials for the production of the same product or other products or are discarded. 
Raw materials and waste or the resulting shear tail iron sheets are left from the cutting residues and cannot be reused for the same purpose. Reclaimed scrap from steelmaking and rolling lines, if not heavily contaminated, is the best scrap to use in a light-cut arc furnace. If this waste is heavily contaminated, it needs to be cleaned up, such as potholes in the road Scrap that is bought from scrap dealers and needs to be prepared for operation can come from commercial goods such as cars and household appliances, as well as from industrial equipment, buildings and bridges.
Types of use of scrap iron
Post-entry waste can be used in two ways: Figure 1: Used in ironworks to reduce melting temperature, improve efficiency and quality Figure 2: The scrap is melted down and made into ingots for the production of raw materials for the foundry Classification of waste
- Metallic
- non-metal
1 - Metal Ferrous metals such as precious metals gold, silver and platinum derivatives and rare elements such as cobalt, mercury, titanium, tungsten, arsenic, beryllium, bismuth, cerium, cadmium, niobium, indium, gallium, germanium, lithium, selenium, tantalum, tellurium. Vanadium and zirconium and non-ferrous metals such as steel, cast iron, aluminum, copper, brass, bronze, lead, zinc, industrial metal waste, and other metal waste. In addition to industrial sites, iron scrap was found around residential areas, collected by recyclers. Scrap iron is very bulky and is sold on a weight basis. But the performance of a part (such as a car engine) affects the price of a wrecker as opposed a wrecker. For scrap inventory, the value of each piece is what the smelter pays for it. 2- Non-metal To distinguish ferrous and metal scrap from non-metals, you need large magnets for separation, which is very important to get more income. Non-ferrous metals are cheaper than ferrous metals and their recycling rates are much higher. But its residues are non-ferrous metals such as copper, aluminum, and brass. 
These metals are more expensive than steel, but they are found in smaller amounts in recycled materials. If a piece is composed of different metals, it can be bought cheaper, as it is impossible to separate the metals in a piece in a warehouse. Scrap recycling process In general, when it comes to recycling, there are two types of material separation: "Sorting at source" through sorting bins at city level and "sorting at destination" at recycling stations.
- Waste classification
After the waste enters the factory by truck, it is piled up in an open farm-like environment, separating the usable parts from it. Cranes are used to inspect and inspect debris. Human agents use tools like magnets to capture metal and sort the waste. Like propane tanks, glass and heavy iron. To reduce risks and hazards on the job, scrap metal is checked by inspectors before separation. The reason for this work is to reduce risks and hazards at work and prevent metal waste from being damaged separately from other non-recyclable waste.
- to pour
After separation, the scrap metal is placed on a conveyor belt and transferred to a shredder. Conveyor belts are sensitive to the weight of scrap metal; if this waste is very heavy, it will take some time to place it on the belt. 
Shredders need a lot of this waste.
- Magnetic separation
This step is controlled by the inspector. The waste entering the unit is divided into large and small pieces and enters the magnetic separator. The steel plate sticks to the magnet, while other scrap passes through and ends up on another conveyor belt. Use magnets to separate valuable non-ferrous metals. Metals collected during this process include copper and brass. This step is usually repeated to ensure that critical waste is not lost or damaged. To prevent that from happening, the inspectors checked the waste pile again.
- Melt
Steel ingot is produced by melting collected steel scrap and scrap. The ingots produced by the foundry are transformed into valuable parts and thus re-enter the consumption cycle.
