the various ore types are the moisture, aluminium, iron and silica content. The silica content of the Cawse ore is mainly present as iron-rich quartz, whereas in Bulong and Murrin Murrin ore, it is incorporated into clays. In lateritic deposits, the nickel and cobalt do not usually occur in distinct minerals. Along with manganese, they are released

Hydrometallurgical processing of nickel lateritic ores

Nickel production is a very important activity for the European Union because nickel is a unique constituent of stainless steel. Europe has lateritic (oxidic) ore deposits along a very well-known belt starting from the Alps and ending to the Himalayas. The lateritic belt passes through western Balkans and Greece and continues through Turkey to Asia. The known lateritic deposits in Serbia are

2021-2-28 · In the processing of nickel, typically lateritic ores or sulfidic ores are first crushed and milled to a fine powder. Water is added to create a pumpable slurry, which is treated with reagents during the flotation process in order to concentrate the nickel. Smelting processes the concentrate further, creating nickel-rich matte, while impurities are removed as slag.
