Different kinds of ores are found in nature. The four primary types of ores are halide ores, carbonate ores, sulphide ores, and oxide ores. Bauxite is an oxide ore, and aluminium is extracted from it. Rock salt is a halide ore, limestone is a carbonate ore, and cinnabar is a sulphide ore. Sodium is extracted from rock salt, calcium from ...

From sulfide ores. Sulfide ores are crushed and ground in order to liberate nickel minerals from the waste materials by selective flotation. In this process, the ore is mixed with special reagents and agitated by mechanical and pneumatic devices that produce air bubbles. As these rise through the mixture, the sulfide particles adhere to their ...

Slag is a by-product of the metallurgical smelting process. Slag has a double role: it permits removal of impurities, known as gangue, from the melt by forming oxides. It also allows exchange reactions with the liquid metal, permitting control of the process in order for the desirable elements to stay in the melt while the others are removed.
