In consideration of ore types, a generalized diagram showing the applicable ore beneficiation technologies for oxide and sulphide ores versus ore grade is given in Figure 2. Figure 2 Applicable Ore Beneficiation Technologies as a Function of Ore Grade for Oxide and Sulphide Ores. (Modified from Robertson et al., 2005)
called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate (enriched ... Other chemicals are used to generate the froth and still others are used to adjust the pH.
Mineral processing operations generally follow beneficiation and include techniques that change the chemical composition of the ore mineral, such as ion exchange, solvent extraction, smelting, electrolytic refining, and acid attack or digestion. The physical structure of the mineral

porcelain etc. There are numbers of chemical compounds used for fusion. The choice of fusion mixture depends on the nature of the ore to be fused and the nature of the final product needed for further analysis. Before entering into the further details of use of wet and dry methods, it
various mineral components, and as extracted from the ore body, they are not useful as they are. Essentially the technology of mineral beneficiation resides in the separation of the mineral components by the least energy-intensive means, and in many cases the solution to this is separating them by the physical rather than the chemical procedures,
