Nickel sulphide concentrate processing via low-temperature

Apr 01, 2019· Nickel sulphate formation is most favourable at 350–450 °C, whereas at higher temperatures, oxide formation is preferred. (2) Nickel sulphate was experimentally proven to be the main nickel containing interaction product of nickel sulphide concentrate and sodium chloride at 400 °C.

Nickel: smelting, producing-Metalpedia

After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then, solvent extraction is used to separate the cobalt and nickel, with the final nickel concentration greater than 99%.

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.

As a general rule, it takes approximately three times the amount of energy to produce one tonne of nickel from a laterite operation as it does to produce the same tonne from a sulphide operation. This is because sulphide resources contain sulphur which is a free fuel source when processing the ore into an upgraded product.
