•The ferrochromium is used as the main ingredient for stainless steel production. •Some of the chromium rich product is sold as a concentrate for foundry sand, for feedstock for chromium chemicals production, for feedstock for chromium metal production and for an ingredient in the manufacture of refractories.
Essentially, chromium is used to produce ferrochrome, which is then used to make steel. China is the world's top consumer of chromium, as well as the world's top stainless steel producer. However, it has no chromium production at all.
Very large amounts of stainless steel are used in food production and storage. The most commonly used grades are 304 and 316. Typical uses would be dairies, milk storage, ham curing, frozen and salted fish storage. Whereas 304 is used for normal temperatures and acid concentrations, 316 is .

China's production of crude stainless steel continued to grow in August, increasing by another 26,000 tonnes or % on month to touch a new high of million tonnes, according to the findings of Mysteel's latest monthly survey among the country's 21 domestic stainless makers.
In the United States, the energy consumed for the production of steel is about 19 MJ/kg from iron ore [3] and 10 MJ/kg from scrap metal [3]. Almost 40% of the world's steel production is made from scrap [7].

The stainless steel sector is the greatest market for primary nickel and about 70% of the primary nickel produced in 2018 was used for stainless steel production, says Masson.
Production. Gold and silver are products of the copper mining and smelting process. They follow the same production pathway as our copper ore from the mine to the smelter. At the refinery, we lower copper anodes (which contain gold and silver) into an acid solution. Gold and silver drop off into the bottom of the tank as electrolytic slimes.
The 10 to 50 cent coins are made of Nordic gold (89% copper with aluminium, zinc and tin). The 1 and 2 Euro coins contain two alloys. The inner part of the coin with a gold colour is made of 75% copper with zinc and nickel and the outer part, a silver colour, is an alloy of 75% copper and 25% nickel.

Metallic iron, from which steel is derived, must be extracted from iron ore. By definition, steel is a combination of iron with a small amount of carbon. Thousands of products having various chemical composition, forms, and sizes are made of iron and steel by casting, forging, and rolling processes.
