Separation Process of Gold Concentrate From Rocks In the processing of gold ore in general should be done gradually, from the newly excavated ore from mines with very low levels of about a few grams / tonne course still needs to be upgraded to high grade gold ore reached levels above ten grams / tonne in the way of enrichment or concentration so that it becomes feasible to extract gold.
How is gold mined? Gold is mined by 4 different methods. Placer mining, hard rock mining, byproduct mining and by processing gold ore. Each of these categories has it''s own unique methods of extracting the gold from the surrounding materials.

Gold panning is mostly a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and shaken, sorting the gold from the gravel and other material. As gold is much denser than rock, it quickly settles to the bottom of the pan. The panning material is usually removed from stream beds, often ...
