gold and silver ore milling processing

It is common thatgold orebeprocessedby two methods - gravity is used to remove the coarsergoldfrom anoreand afterward theoreisprocessedby cyanide to recover the fine particles ofgold and silver. Gravity concentration methods are the ones most commonly used by the individual prospector.
