  Gold Leaching Equipment, Circuits & Process Plants

  2016421 · Leaching Gold Circuits. This flowsheet is the lowest in price, and can be used on what are commonly termed as “free milling” gold ores where a high percentage of the values are free and where these values are unlocked at reasonably coarse grinding. This flowsheet is often used for treating high grade pockets.

  Column Leach Testing | GSL

  Column Leach Testing. Column leach testing is typically performed once your ores amenability to heap leaching has initially been confirmed using the cheaper and faster coarse ore bottle roll test method. GSL offers column leach test programmes which can be used to investigate factors including crush size, agglomeration conditions, cyanide ...
