Nickel Smelting and Refining
the storage and recycle of plant process water. However, there may be a need to treat bleed streams of some process effluents to prevent a buildup of various impurities. Solid wastes from nickel sulfide ores often contain other metals such as copper and precious metals, and con-sideration should be given to further process-ing for their recovery.

leaching (HPAL), Caron process, and direct nickel process (DNi) are the most common processes to treat lateritic ore [4]. HL process can be processed at ambient temperature, but it is a kinetically slow process, and the yield is low compared to AL and HPAL [5]. AL requires 1 bar pressure and tem-perature in the range of approximately (50–90 °C).

Recent Progress in Hydrometallurgical Processing of Nickel Lateritic Ore
An investigation on the reduction roasting and ammonia leach methods of treating lateritic nickel ore (Caron process showed satisfactory extractions for limonitic ore, i.e., material high in iron oxides and low in silicates) is reported . The Caron leaching method works with oxide laterites ("limonite") that can tolerate some silicate ...

Nickel Refining
7.3 Nickel Ore Processing and Refining. Primary nickel is produced from two very different ores, lateritic and sulfidic. Lateritic ores normally are found in tropical climates, where weathering, with time, extracts and deposits the ore in layers at varying depths below the surface. Lateritic ores are excavated using large earth-moving equipment ...
