    i. Coarse Grinding: Rod mills are generally used as coarse grinding machines. They are capable of taking feed as large as 50 mm and making a product as fine as 300 microns. – ii. Fine Grinding: Fine grinding, which is the final stage of comminution, is performed in ball mills using steel balls as the grinding medium.

  • Copper Mining and Processing: Processing of Copper Ores

    The first steps of copper processing are the same for both ores: mining and transporting. Copper mining is usually performed using openpit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and

    The mineral beneficiation involves separations of gangue minerals from ore and is done in the following two stages: 1. Liberation of valuable mineral by size reduction technologies. In most ores the valuable minerals is distributed in the matrix of ore. 2. Concentration technologies to separate the gangue minerals and to

  • CHEMGUIDE: Different process involved in metalurgical process

    The actual process of extraction of a metal from its ore depends upon the nature of the ore and the metal. The removal of the undesired foreign impurities i.e., gangue, from the ore is called concentration (or beneficiation) of the ore. This method is slow and is generally adopted in the initial stages of concentration.
