Gold and Tailings: The Standard Mill at Bodie, California
When gold exists in ore in such a state that it can be extracted by simple amalgamation, it is called free-milling gold. The amalgam of gold, silver, and mercury can be converted to a block of bullion by treating it in a retort, which is essentially a mercury still. The amalgam is placed in a furnace and heated to a temperature in excess of 400° C, at which point the gold and silver are
Free-milling ore Article about free-milling ore by The
[4] performed an analysis of the influence of microwave heating in a free-milling ore.They found that by using dielectric heating, the crushing strength (an important variable for grinding) was reduced by 31.2 % and the reception of reagents was increased, thus reducing the leaching time from 22 hours to just 12.
Milling Technology in the Nineteenth Century ONE
During the nineteenth century, Nevada industrialists revolutionized the milling of gold and silver ore. Nineteenth-century millers used various techniques. Most employed mercury, a metal that readily bonds with gold and silver to form what is known as an amalgam. This compound—once a standard for dental work—could be heated to boil off the mercury, leaving the precious metal behind. Placer
