Nickel / cobalt mining extraction procedures Industrial ...

In general, nickel is obtained by roasting nickel sulphides in air to obtain NiO. This is then reduced with carbon to obtain nickel metal. The nickel is purified by combining carbon monoxide with impure nickel at 50°C and atmospheric pressure, or from the mixture of nickel and copper, under more complex conditions, obtaining Ni(CO) 4 , which is volatile.

Nickel: smelting, producing-Metalpedia

Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.

Nickel processing - Extraction and refining Britannica

2 天前  Nickel concentrates may be leached with sulfuric acid or ammonia, or they may be dried and smelted in flash and bath processes, as is the case with copper. Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickel-iron sulfide known as matte, which contains 25 to 45 percent nickel.
