For instance, pyrites are present only, all the gold may be in or on the surface of these, and none in the stone; if arsenical pyrites are present there will generally be more in the arsenical; while if sphalerite or zinc sulfide occurs, the gold clings to it by some process of natural selection, the silver going to the galena. In this case ...

The district is known for production of gold with minimal silver and very little quartz. The Parker is a fine example of this model with native gold in pyrites in small veins from 2 to 18 inches in width exposed in the underground workings.

Dec 20, 2018· 65 characterised by high sensitivity, uses cheap equipment, and allows determining the elements in a 66 wide range of defined contents. When determining the gold content in mineral raw materials 67 containing gold, silver, and platinum metals, a necessary stage in the analytical process is their 68 separation from the sample matrix [17–19].

Gold ore. Prominer maintains a team of senior gold processing engineers with expertise and global experience.
