Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the nickel industry.

This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a very long and forlorn process that separates the useful components from the waste materials such as slag.

Mine tailings include process-affected water, containing dissolved metals and ore processing reagents and fine-grained ground-up rocks after minerals of value have been extracted from mined ore. In tailings pond, the residues are usually deposited as water-based slurry before recycle/reuse or discharge to environment.

Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth’s sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite.

The first process takes place at limestone mines where the mined ore undergo crushing and screening for the separation of the different size fractions of the ore. In the iron and steel plant, in some of the places, raw limestone is further processed.

Limestone. For other uses, see Limestone (disambiguation). Limestone is a common type of carbonate sedimentary rock. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate ( CaCO3 ). Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can
