Then the ore is separated from the gangue by various operations known collectively as mineral processing, or ore dressing. The desired metallic element is then extracted from the ore by various smelting, roasting, or leaching processes. Advances in hydrometallurgy have meant that some metals—such as copper, uranium, and gold—can
The Mining sector covers the extraction and processing of metal and mineral ores and deposits, including coal, copper, iron, limestone, nickel, precious metals, potash, uranium, diamonds, minerals, rare earth elements and much more. The Mining Platform identifies mine type (above-ground, underground and solution) and mining method. ...

Mineral processing (or mineral dressing) is a specialized area in the science of metallurgy that studies the mechanical means of crushing, grinding, and washing that enable the separation (extractive metallurgy) of valuable metals or minerals from their gangue (waste material).
Ores definition, a metal-bearing mineral or rock, or a native metal, that can be mined at a profit. See more.
The first process that most of the ores or minerals undergo after they leave any mine, is mineral processing or mineral/ ore dressing. It is a process of ore preparation, milling, and ore dressing ...
Examples of ores include aluminum, copper, clay and sodium. An ore is a naturally occurring mineral, rock or metal that can be mined in sufficient amounts to sell for a profit. Ores can also be a natural product that can be used as a source of a nonmetal. Other examples of ores include gold, magnesium, silver, tin, scandium and beryl.

CHAPTER 1 MINERAL DRESSING. So mineral dressing or ore dressing is commonly regarded as processing of raw ores to yield marketable products by such physical means those do not destroy the physical and chemical identity of the ore. 1.2. Economic Justification of Mineral Dressing: 1.
EPA promulgated the Ore Mining and Dressing Effluent Guidelines and Standards (40 CFR Part 440) in 1975, and amended the regulation in 1978, 1979, 1982 and 1988. The regulation covers wastewater discharges from ore mines and processing operations. The Ore Mining Effluent Guidelines and Standards are incorporated into NPDES permits.
Ore Dressing The ore will be sorted after being crushed and the useful minerals and gangue are selected, or the various useful minerals are separated from each other, which is the main part of the beneficiation. The ore dressing methods include magnetic separation, gravity separation, froth flotation, electrification, and chemical separation.
