This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either openpit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores are treated and the metals extracted.
Magnetite ore (Fe3O4) is a ferromagnetic mineral commonly used in magnetic separation coal washing processes. Coal washing using magnetite is used to remove contamination from runofmine (ROM) coal, which usually contains rocks, middlings, used consumables and other contamination introduced by the mining process.

14 SEPARATION TECHNIQUES Introduction The methods for separating, collecting, and detecting radionuclides are similar to ordinary analytical procedures and employ many of the chemical and physical principles that apply to their nonradioactive isotopes. However, some important aspects of the behavior of radionuclides are
Some minerals require a physical and/or chemical process to remove them from the ore. Large rocks containing minerals need to be crushed and milled. The valuable minerals are then separated from the rock using a variety of physical and chemical separation methods.
Posts about chemical separation written by davidvblack. The technology for refining ore went through rapid change in the 1920s. The smelter only operated for about four years, at which point it became cheaper to ship the ore by rail to the more modern smelters in Murray.
This answer I wrote earlier today will explain how it''s done once the gold is poured into doré at the mining site. answer to What is the chemical method used to refine gold? Now, if you''re searching for how it is first separated from the rock, thi...
FROTH FLOTATION "So many variables influence flotation that it will be long before every one of them can be investigated and its influence on the process determined." The froth flotation process was patented by E., H. F. K. Pickard, and John Ballot in 1906, 19 years after the first cyanide process patents of MacArthur and the Forests.

Frothers are liquids that produce the froth or on which the flotation process depends. The froth resembles soap suds and provides the physical separation between the mineral(s) floated and the pulp containing the waste. The froth must be strong enough to support the weight of the mineral floated and yet not be tenacious and nonflowing.
