Nickel processing
Nickel processing - Extraction, Refining, Alloying: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel …

In contrast, the subsequent processing of MSP must be performed by pressure oxidative leaching. On the other hand, MSP has advantages in terms of higher nickel content ( Ï 55%) and lower contents of impurities. The moisture content of MSP is also lower than that in MHP which leads to the lower transportation cost.

Rotary Dryers in Nickel Laterite Ore Preparation
To avoid such challenges, a drying step is therefore critical, removing the free moisture so that nickel can be beneficiated from the ore. Drying, which may also be referred to as dewatering in this context, typically brings the moisture content down to around 5-8%, though in some cases it may be as high as 20%.
