To complicate matters further, these ore bodies are often refractory, where the gold is locked within sulphide minerals; or double refractory, in which gold is locked within sulphide minerals and preg-robbing due to the presence of organic carbon. These must be pretreated ahead of leaching.Processing the gold ore (ESBRM) For every ton of ore that is mined, only a very small amount (about $$\text{5}$$ $$\text{g}$$) of gold is extracted. A number of different methods can be used to separate gold from its ore, but one of the more common methods is.Read more

#### Gold processing 101

· If this ore also contains 1g/t Au (for GSR =1), and 90% recovery to concentrate is achieved, then 0.90g will be recovered and with a concentration ratio of 20 (5% to concentrate) this corresponds to 18g/t Au in concentrate.

#### Ore Sorting Strategies In Mineral Processing

Ore sorting is one of the oldest forms of mineral processing and can be done in many different ways. Here we compare ore sorting to dense medium separation. For successful mineral processing design it’s critical to evaluate the possibility of preconcentration or waste diversion before grinding. ...Gold deposits can be grouped into two primary classes: placer deposits, where the gold is exposed from weathering and erosion, and hard rock, where the gold is still trapped within the host rock. Gold recovery methods for these two types of deposits vary greatly from simple panning to a complex network of grinding, chemical leaching, gravity concentration and more.Read more
