gold recovery. The single most important variable in effective recovery of gold is the efficiency of the cyclone to for retaining gold within the grinding circuit. Poor partition behaviour of the cyclone combined with upsets in the cyclone feed stream can is the most significant cause of reduced gravity gold recovery.

A standard ball mill may grind your ore to 75 microns. Fine grinding is one process available to liberate refractory gold. Gravity Recoverable Gold (GRG) refers to how much gold you can recover based on how fine you are grinding/milling your ore. The GRG (Gravity Recovery Gold) testing is available at Met-Solve Labs.

The recovery of gold using only flotation resulted in a recovery of 95.3% and the combination of gravity and flotation yielded an overall recovery of 94.7%. Although similar, the concentrate grade achieved by gravity and flotation concentration was double that of simple flotation and therefore may be the better option if direct smelting or sale ...

A flow sheet has been developed to treat a high tonnage highly preg-robbing gold ore. The ore is low grade and fine grained with a high proportion of very fi ne free gold. The key components of the flow sheet include gravity, flotation, intensive cyanidation with direct electrowinning, and carbon-in-leach of the flotation concentrate. The circuit produces a low overall mass pull to concentrate ...

The testwork shows a good gravity gold recovery of 76.0% with an additional recovery of up to 21.3% with cyanide leaching of the gravity tailings. Also grindability results indicated a slightly softer ore than expected, with the possibility to install a smaller mill than assumed in the scoping study.
