Cost of Producing Concentrates from Ore

From the viewpoint of mineral economics, the ultimate and significant production cost is that per unit of metal produced rather than the cost per ton of ore treated. This viewpoint is natural to processors of ores whose final product is refined or unrefined metal, whether theypanies engaged solely in smelting, orpanies engaged in mining, milling, and smelting

Artisanal and Small Scale Gold Mining Without Mercury

To separate gold particles from a concentrate, concentrate is fed into the centrifuge through a pipe at the top of the machine in a slurry of around 60 75 water and 40 35 solids. The material collects in a vessel in the center of the machine where high speed rotation creates force that moves the material up the sides of the vessels walls.

Processing, smelting and refining gold  World Gold Council

The two gold refining methodsmonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point impurities separate into a layer on the surface of the molten purified gold.

Golde 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. . You will get one of the 1 gallon bags for the cost of $50.00 each.

Extracting Gold  HowStuffWorks

This causes gold to collect on the negative terminals. ­Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F 1,149 degrees C. When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers
