  Mineral beneficiation and ore dressing - Unacademy

  5  · Mineral beneficiation is the process of separating economically essential minerals from their respective ores. For example, aluminum is extracted from bauxite ore. Ores are the aggregates of rocks from which the desired minerals are extracted. They can either contain minerals or metals that are economically important to humans. If the quantity of …

  Attempts at the beneficiation of lateritic nickel ore

  198751 · Abstract. The processing of lateritic nickel ore is quite difficult, since the nickel-bearing minerals are finely disseminated in the ore bodies. Hence the establishment of beneficiation techniques has long been needed. The authors carried out comprehensive research on concentrating lateritic nickel ore, looking for some means of utilizing ...

  Some factors that affect beneficiation of sulphide nickel–copper ores

  Two nickel sulfide deposits in southern Africa were chosen as case studies to understand differences in DMS efficiency when applied to different ores: Ore A and Ore B. Both ores showed nickel upgrades using DMS and the products were then characterized using QEMSCAN, with the aid of X-ray diffraction and electron probe microanalysis.
