Gold processing Mining and concentrating Britannica
1 天前 · Gold processing Gold processing Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for

Explain magnetic separation process of ores with the
Magnetic separation process of ores: An electromagnetic separator is required. A leather or brass belt moves over two rollers, one of which encloses magnets in it. The powdered ore is dropped over this moving belt at one end. The non magnetic part of the ore is not attracted by the magnet and falls to form a separate heap at a distance.

Concentration of Ores Study Material for IIT JEE
This method of separation is used when either the ore particles or the gangue associated with it possess magnetic properties. For example, chromite Fe(CrO 2) 2 being magnetic can be separated from the non-magnetic silicious gangue by magnetic separation.. This method is widely used for the separation of two minerals, when one of them happens to be magnetic.
