Mercury

tailings generated. Mercury, a dangerous pollutant, is the preferred method employed by small-scale miners for gold recovery. Gold extraction using mercury is comprised of the following four stages: 1) amalgamation, 2) separation of amalgamation, 3) removal of excess mercury, and 4) burning of the remaining amalgam to produce a gold sponge.

Separating gold/sand

Aug 12, 2011the old timers had a slow but successful method of separation that doesn't require any dodgy chemicals. you simply dry out the black sands, magnet off the black sand, place the remaining particles of sand/gold/black sand dust etc on a white piece of paper and gently blow until the lighter materials blows to the outer edge of the paper.

How gold is made

Gold, recognizable by its yellowish cast, is one of the oldest metals used by humans. As far back as the Neolithic period, humans have collected gold from stream beds, and the actual mining of gold can be traced as far back as 3500 B.C., when early Egyptians (the Sumerian culture of Mesopotamia) used mined gold to craft elaborate jewelry, religious artifacts, and utensils such as goblets.
