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 processing 101 - Mining Magazine

Sep 07, 2017  Metallurgical processing of metalliferous ores in general and gold ores in particular, consists essentially of three stages, often colloquially referred to as: Bashing (crushing); Mashing (grinding); and. Hashing (extraction/recovery) In the context of flowsheet selection, the bashing and mashing stages are relatively straightforward.

Refractory Gold Technology

Many gold ores and concentrates contain fine grained gold locked within sulphide minerals, such as pyrite and/or arsenopyrite, unavailable for recovery by conventional leaching. In Sherritt’s gold process, the sulphide and arsenide minerals are completely oxidized by pressure oxidation, thereby liberating the gold.
