method for the processing of minerals

Mining And Mineral Processing The Lithosphere Siyavula

Once a suitably sized deposit of a mineral has been found, mining can begin. In ancient times mining and mineral processing were very primitive and the main method used to extract ores was digging by hand. Mining is largely divided into surface and underground mining. Minerals are often found in river beds, beach sands and other sandy areas.

Gold Processing Methods & Gold Ore Extraction

Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery

Innovations: Introduction to Copper: Mining & Extraction

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfurbearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
