Gold concentrates come from a open pit hard rock mine in the North Ga Mountains We dig quartz rock out of our pit mine then run it trough our Stampmill to crush it into sand That material is then ran through our Trommels and that is how we make our concentrates

The ore was placed in the bottom of the arrastre over which were placed large rocks The rocks were ground over the ore crushing it and releasing the gold Mooseland prospector Eldon Cameron with hat and unknown prospector c 1936 examine a flatMore Detail +
The heap leaching process being employed at Lomati Mine is a commonly used process to extract gold from the ore Generally the ore is crushed into fine particles before being heaped and sprayed with a leaching solution which liquefies and separates the gold from the oreMore Detail +
Leaching Gold from Finely Crushed Ore Sand Leach When the cyanide process was first introduced its application was confined to leaching that is treatment by percolation By this method only such material could be worked as was sufficiently granular in texture to allow the necessary amount of solution to percolate through it in a reasonable timeMore Detail +
Alluvial Gold Mining Alluvial gold is found beneath the surface at the bottom of a creak or stream Alluvial gold mining is the process of extracting gold from these creaks rivers and streams and is generally considered to be the most environmentally friendly method of gold mining as a result of the reduced environmental impact when compared to underground miningMore Detail +
Leaching Gold from Finely Crushed Ore Sand Leach By crushing the ore dry it is sometimes possible to leach it direct without removing the slime but in the majority of cases this is not feasible and it is necessary to separate the sand from the slime leaching only the former and treating the latter by agitationMore Detail +
NFinally once the rock is fully crushed we get to the part about separating out the gold from the crushed rock Often this is accomplished simply by very careful panning Panning is the most suitable method if you only have an amount of rock less than about 15 or 20 pounds On the other hand if you are going to be processing largeMore Detail +
Once the ore has been broken up into fine dust testing for free gold content in hardrock ore can be done using some type of gravity method A simple gold pan can be used to sample small amounts of crushed ore or if a decent water supply is available then it can be run through many types of separation devices Shaker tables are commonly used and although quite expensive work exceedinglyMore Detail +
One way to clean it is to wash the ore in a solution of nitric acid Mercury can be introduced in several ways – one is to rub it on the bottom of a pan pour in a solution of the cleaned slurry and water and then agitate the mixture The gold combines with the mercury which can beMore Detail +
Pour the acidandbleach mixture into the plastic bowl with the ore grains and stir Allow four hours for the gold to dissolve stirring every 20 minutes The chlorine reacts with the gold inside the ore to form gold chloride Filter the ore and bleach solution to remove allMore Detail +
