Recycling and pollution control. Due to their extensive use, nonferrous scrap metals are usually secondary materials in scrap are vital to the metallurgy industry, as the production of new metals often needs them. Some recycling facilities resmelt and recast nonferrous materials; the dross is collected and stored onsite while the metal fumes are filtered and collected.

Ferrous metallurgy. Ferrous metallurgy includes extraction of iron, smelting and refining of iron ore, rolling and ferroalloys production. The ferrous metallurgy production of the country started to meet the demand of oil and gas industry (due to pipe production) and grew further in order to improve other branches of the industry.
Whenever sulphide or quartz is associated with gold, the resultant gold ores are typically amenable to a certain degree of particle sorting. And in the case of the complex blend of quartz associated with gold, the preconcentration of the ore by means of sensorbased ore sorting during the early stages of the production process can be effected by harnessing the scattering effect of a LASER beam.
ADVERTISEMENTS: India''s mineral resources are sufficiently rich and varied to provide the country with the necessary base for industrial development. The position is particularly advantageous in metallic minerals of the ferrous group, including the ores of iron, manganese, chromite and titanium. India''s reserves of mica and bauxite also are rated among the largest in the [.]
