  • Methods for Separating Mixtures Chemistry for Non Majors

    One of the approaches taken to isolate the gold from the soil was called panning. Dirt would be placed in the pan and covered with water. After thorough mixing, the pan is gently swirled to remove dissolved material while the heavier gold settles to the bottom of the pan. The gold is then separated from the mixture of soil and water.

  • The Extraction of Gold by Chemical Methods Nature

    Abstract. EXCLUDING mechanical, smelting, and amalgamation processes, the methods of extracting gold from its ores may conveniently be grouped together under the heading of wet or chemical methods. In these, the gold is dissolved by some suitable solvent, and is then separated from the unaltered ore by washing, and recovered by precipitation.
