REFRACTORY GOLD - PanTerra Gold Limited
By definition, refractory gold ores contain gold that is resistant to extraction by conventional stone processing and as a result responds poorly to traditional gold cyanidation techniques such as Carbon-in-Leach (CIL), yielding less than 80% of the contained gold. Refractory gold consists of extremely fine grained gold particles that are either physically encapsulated within, or chemically bound within, a …

Often when gold is locked in sulphides and silicates it is necessary to reduce the particle size to a size where gold is liberated or partially liberated. For refractory ores this generally translates into grinding below 10 microns and often to as low as 3-4 microns.

Refractory Gold Mining SGS The other parameter that SGS experts consider when designing refractory gold treatments is whether or not to preconcentrate the gold-bearing ore. This is usually done by flotation of arsenopyrite, pyrite, or other gold-bearing sulfides. To be economically justifiable, preconcentration should meet two objectives.

Refractory Gold Mining SGS. SGS has developed a series of testing and mineralogy assessment protocols that allow us to determine the character of refractory gold and the mass balance between refractory and free-milling gold. Once the deportment or textural associations of the gold is determined and the mass balance known, flowsheet options are
Refractory Gold | Mining | SGS
Gold in sulfide minerals could be liberated by oxidization using techniques such as roasting, high temperature pressure leaching or bacterial leaching. Also, grinding the ore to an extremely fine particle size can liberate gold encapulsated in sulfides. SGS has very extensive experience with all the unit operations involved in the processing of refractory gold ores, and in selecting the optimum flowsheet for a particular ore. Our gold metallurgy …

Gold extraction - Wikipedia
A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre-treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic carbon, or both. Sulfide minerals are impermeable minerals that occlude gold particles…
