What is the Alluvial Gold Mining Method?

Nov 12, 2019· The principle of gravity separation used for the alluvial gold mining is to separate the gold concentrate from other minerals according to the different ore weight in the original ore. The first step of the gravity process is desliming, which removes the dirt from the mineral.

How to concentrate the alluvial gold with much magnetic

Other point to keep in mind is the specific gravity of the magnetic minerals, usually they range from 4.5 to 6.5, these values are much lower than the specific gravity of gold, 19.3. The shaking table can be used to clean the concentrate from the spiral concentrator. Apparently you work in a lab.

Gold processing Mining and

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
