Refractory Gold. The last type of gold deposit is called refractory gold, and it is the most difficult type to extract. It can be defined as any ore that responds poorly to a conventional gravitycyanidation process with examples including copper porphyry, complex sulfides, arsenopyrite and leadzinc associations.
to show the effect of pregrobbing on gold extraction from ores of different mineralogy. The effect of pregrobbing was found to be closely related to the kinetics of the pregrobbing and adsorption processes. This batch model was extended to a continuous model that simulated three leaching and seven carboninleach tanks. The effect of processing the oxide and sulphide ores studied was ...

Cupellation is a process where ores or alloyed metals are treated under high temperatures and controlled operations to separate noble metals, like gold and silver, from base metals like led, copper, zinc, and others present in the ore or alloyed metal. The process is based on the principle that precious metals do not oxidize or react chemically, like the base metals; so when they are heated at ...
Biomining is mineral processing with microbes. Biomining is the process of using microorganisms (microbes) to extract metals of economic interest from rock ores or mine waste. Biomining techniques may also be used to clean up sites that have been polluted with metals. Valuable metals are commonly bound up in solid minerals. Some microbes can oxidize those metals, allowing them

A process for recovering gold from a refractory sulfidic ore which has been suspended in an aqueous slurry and oxidized using nitric acid so that substantially all of the gold in the ore is made available for recovery and at least a portion of the sulfidic components present during the oxidation are oxidized to elemental sulfur, comprises bubbling air as a discontinuous phase upwardly through ...
· The reason for lower holistic gold recovery in CIL method compared to carboninPLS could be attributed to a slower gold extraction from the ore to the solution, which in turn reduces holistic recovery. This assumption was supported by observing 72% extraction of gold from ore into the solution in the CIL1 test, while longer retention time (36 h) enhanced the dissolution of gold to 83% .
