Nickel Smelting and Refining IFCDirect Nickel Process Breakthrough Technology

Nickel Smelting and Refining Industry Description and Practices Primary nickel is produced from two very dif ferent ores lateritic and sulfidic Lateritic ores are normally found in tropical climates where weath ering with time extracts and deposits the ore in layers at varying depths below the surface Lat eritic ores are excavated using large earth mov ing equipment and are screened to Processing of Nickel Ores and Concentrates 15 3 the ore is dissolved into the nitric acid leaving behind the acid insoluble minerals usually consisting of silicates and the pregnant leach solution PLS

Microwave Treatment of Ultramafic Nickel Ores Heating Copper Nickel Flotation

Ultramafic nickel ores are difficult to process and the difficulty is largely due to the presence of serpentine Mg 3 Si 2 O 5 OH 4 Serpentine is an anisotropic mineral with multiple pH dependent surface charges and a nonspherical morphologyCyclic Copper Nickel Flotation Tests To further clarify the flotation response of the shaft sample several cyclic tests were carried out A 6 min grind in the laboratory ball mill was selected for these tests and the result was a 40 pct minus 325 mesh grind
