Annual generation of hard coal mining waste in 2001 accounted for 38.4 Mt and waste from ore mining, almost entirely tailings, accounted for 29.9 Mt. Current percentage of mining waste use was relatively high and accounted for 91.0% of generated coal mining waste and 75.1% of ore mining and processing.
We looked specifically at ferrous slag, the leftover material from the smelting of iron and steel, in the Chicago-Gary area of Illinois and Indiana. Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded.

Hand tool - Hand tool - Iron and steel tools: Iron technology was derived from the known art of reducing copper and bronze. The principal requirement was a furnace capable of maintaining a reducing atmosphere—i.e., one in which a high temperature could be maintained from a good draft of air. The furnace had to be tall enough to allow the iron to drop from the smelting zone and form a slaggy ...
Cort used a coal-fired reverberatory furnace to melt a charge of pig iron to which iron oxide was added to make a slag. Agitating the resultant "puddle" of metal caused carbon to be removed by oxidation (together with silicon, phosphorus, and manganese).
The resource treatment and comprehensive utilization of metallurgical steel slag iron slag refers to magnetic separation and removal of iron from metallurgical slag and the use of tailings for the production of building materials.
The two types of concrete aggregate that are manufactured using iron and steel slag as a raw material and which are covered by JIS standards are blast furnace slag aggregate and electric arc furnace oxidizing slag aggregate. Each of these types includes course aggregate and fine aggregate.
History. Mining waste is one type of special waste When EPA proposed regulations for managing hazardous waste under Subtitle C of Resource Conservation and Recovery Act (RCRA) on December 18, 1978 (43 FR 58946), the agency deferred hazardous waste requirements for six categories of waste—which EPA termed "special wastes"—until further study and assessment could be completed .

Iron Ore, Kentucky Geological Survey, University of Kentucky. The Kentucky Geological Survey gets many inquiries about iron slag or pig iron, a product of the iron furnaces. Pig iron is commonly mistaken for meteorites, and although this slag is metallic, heavy, and resembles meteorites, it is just a byproduct of a past mining industry.

Slag is composed primarily of silica and lime, with concentrations of other minor constituents, including alumina, magnesia, and other compounds. During the fluxing process, slag removes the non-ferrous constituents from the molten iron, which purifies the product.
Euroslag - EuroslagFerrous slag is the by-product of iron and steel manufacturing. It arises from the conversion of ores to iron, hot iron to steel, from melting scrap in an electric arc furnace or from the subsequent treatment of crude steel. Each year, about 45 million tonnes of ferrous slag (iron and steel slag) is generated in Europe.
