Designing Gold Project Flowsheets. It has been said that gold was one of the first metals to be mined. As deposits with free, coarse gold were depleted and the volume of mining increased, process flowsheet design became more and more complicated. Gravity was the first method developed to recover gold from ore.

Gold flotation. Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfidecontaining gold ore with high floatability. In addition, the flotation process is also used for polymetallic goldbearing ores such as goldcopper, goldlead, goldcopperleadzincsulfur ore.

Step 5: Refining and Smelting. The eluate solution is pumped through electrowinning reactors where gold is plated onto cathode steel mesh or wool. (Electrowinning is a process of recovering metals from a solution by passing a current through it). The plated gold is then washed off and dried in cylinders called calciners, inside heated furnaces.
