Panning is a gold mining method that uses water to separate the heavy gold particles from the lighter materials in the ore. When panning for gold you put your crushed gold ore in a wide pan and then add water to it. You then swirl the pan around with the aim of removing the lighter materials along with …

As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. Filtering the pulp through screens separates the gold-bearing carbon. The carbon moves to a stripping vessel where a hot caustic solution separates the gold from the carbon.Web
