extracting gold howstuffworksat a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. the gravel like material then enters rotating drums filled with steel balls. in these drums, the ore is ground to a fine slurry or powder. next, mill operators thicken the slurry with water to form pulp and run the pulp through a series of leaching tanks. leaching dissolves the gold out of the ore using a chemical solvent.
how is gold extracted from gold ore? sciencingpreparation. most gold ore now comes from either open pit or underground mines. the ores sometimes contain as little as 5/100 of an ounce of gold per ton of rock. in all methods of gold ore refining, the ore is usually washed and filtered at the mine, then sent to the mill. at the mill, the ore is ground into smaller particles with water,

rebellious ores sulfides, selenides and telluridesmany types of valuable ores contain sulfides, selenides or tellurides and they can make processing these ores more difficult. recognizing these minerals can help us understand and find gold deposits in the field.
gold mining process development denver mineral engineersthe flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. in a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. highly oxidized ores generally do not respond well to flotation.GET A QUOTE
