Read MoreMost nickel is used in alloys with steel, especially stainless steel. It is also used in catalysts and as a plating to protect other, more reactive metals. It is used extensively in coins. The U.S. 5 cent piece is known as a nickel due to its one-time 75 % nickel content. That …
Read MoreNickel sulfide deposits, the principal ore mineral being pentlandite (Fe,Ni)O(OH), are formed from the precipitation of nickel minerals by hydrothermal fluids. They are also called magmatic sulfide deposits. The main benefit of sulfide ores is that they can be concentrated using a simple physical separation technique called flotation.
Read MoreNickel smelting is the process that nickel ore goes through to eventually remove impurities and leave just the nickel metal. While the ores can come from different stones and sources, they have two categories: lateritic, or rocks found in tropical climates and which contain nickel; and sulfidic ore, which is mined from underground. …
Read MoreIndonesia is the world's major supplier of nickel ore, particularly the type of laterites nickel ore. Carrying nearly 25 % of the world's nickel ore is supplied from the country. But on the other hand, the price of Indonesian nickel ore is largely determined by developments in the world price of nickel metal. Almost all products of nickel ore from the mines in Indonesia is still exported ...
