Read MoreIn 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.
Read MoreThe making of nickel is a process which involves a number of steps: 1. Mining. Nickel mined from lateritic ore is mined from various depths beneath the surface using large earth-moving equipment. The other nickel containing type of ore, sulfidic ore, is usually found in combination with copper ore and is mined underground.
Read MoreProcess Methods There are two main methods in processing of laterite ores: pyrometallurgy (smelting) and hydrometallurgy (leaching). In pyrometallurgical route, the ore is generally dried first, then calcined in a rotary kiln and then smelted in an electric furnace with carbon. This method is abbreviated as RKEF (rotary kiln electric furnace).
