Nickel processing Extraction and refining | Britannica

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 surfaces and are collected as a concentrate containing 6 to 12 percent nickel. The

Nickel processing | Britannica

The nickel content of laterites varies widely: at Le Nickel in New Caledonia, for example, the ore delivered to the smelter in 1900 contained 9 percent nickel; currently it contains 1 to 3 percent. Mining. With nickel found in two radically different types of ore, it is not surprising that the mining methods differ. Sulfide deposits are usually mined by underground techniques in a manner similar to copper, although some deposits have been mined using open pits in the early stages. The mining

Hydromet Technology Vale

The new hydrometallurgical process that Vale developed will process the nickel concentrate directly to metal products without first having to smelt the concentrate. The concentrate will be processed in a pressurized vessel where it will react with oxygen and sulphuric acid to produce an impure solution of nickel, cobalt and copper. This solution will pass through a number of chemical purification steps ending with removal of impurities and separation of nickel,

HPAL Plants & Nickel – The Facts

HPAL is a much more complicated process to ramp up and operate than pyrometallurgical processes used to make nickel pig iron (NPI) or ferronickel. Well, in terms of the logistics of an operational HPAL process, there isn’t one. HPAL is clearly the optimal solution for producers looking to get the best bang for their buck in the nickel space, but there are only a handful of successful HPAL
