FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

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

Gold Refinery the process, machineries and project

Gold is recovered from industrial, dental, porcelain or jewellary scrap. For refining, gold bearing alloys are processed on different methods, depending on their carat content. Two methods are commonly employed for purification the Miller process and the Wohlwill process. Alternatively, it can be a complex mix of burning, drying, grinding
