  • Gangue an overview ScienceDirect Topics

    In order to produce clean concentrates with little contamination with gangue minerals, it is often necessary to grind the ore to a fine size (<100 μm). Fine grinding increases energy costs and can lead to the production of very fine difficult to treat “slime” particles which may be lost into the tailings, or even discarded before the

  • Gangue Mineral an overview ScienceDirect Topics

    If the gangue mineral in an iron ore is predominantly quartz, reverse flotation is usually used in the cleaning stage to improve the concentrate grade. Figure 9.13 presents a typical flow sheet for processing an oxidized iron ore containing about 30% Fe using a combination of SLon magnetite separators and reverse flotation. The ore is mainly composed of magnetite, hematite, martite, and quartz.

  • Basic Principles & Variables Affecting Froth Flotation

    The mineralogical character of the ore determines also the extent to which grinding must be carried before flotation is applied. This matter has been previously discussed. In the agitation-froth process, the recoverable mineral content of an ore, the amount of a given oil necessary, the percentage of solids in the pulp treated, the grade of concentrate and the recovery attained are strictly

  • Copper Ore Processing Methods

    The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger

  • Crushing and pulverizing Article about Crushing and

    Crushing and pulverizing are processes in ore dressing needed to reduce valuable ores to the fine size at which the valueless gangue can be separated from the ore. These processes are also used to reduce cement rock to the fine powder required for burning, to reduce cement clinker to the very fine size of portland cement, to reduce coal to the

    Weakly metamorphosed iron-formation is extremely fine grained and requires very fine grinding (as fine as 0.03 mm in some cases) to liberate iron minerals from gangue. More intensely metamorphosed ore is coarser grained and requires less grinding. Maximum grain size after grinding is generally about 0.1 mm, even for the most coarse grained ore.

    Some ores, such as iron ore, are found in relatively high percentages and are fairly easy to separate. Therefore, the resultant tailings are coarser than those from other ores, such as copper, which is found in very low percentages, and requires very fine grinding for separation. Hence, copper tailings are usually quite fine-grained.
