  • An Overview of Basic Gold Separation Methods </h3>PANNINGThis is a mining method that employs the processes that increase the concentration of gold in the ore by selectively removing the lighter materials. This is the most effective method when gold is found in rocks or other hard soils. First the rock containing the gold ore is crushed to decrease its grain size. The grain size of the crushed rocks should be of uniform size to increase the success of this method. Once this has been done one of the following methods may then be used.
