FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

Many modern gold plants incorporate gravity circuits as part of their overall flowsheet, and it is estimated that about 10% of the new gold produced each year is recovered by this technique. The advantages and disadvantages of gravity separation are similar to heap leaching. It is a very simple and low cost process, but gold recovery is usually low
