Rock Crushing Methods And How To Recover Gold From Ores
gold is often found associated with the mineral quartz. It is sometimes associated with other minerals as well, including iron and manganese oxides, calcite, pyrite and other sulfides as well. It is not uncommon for prospectors, especially those who operate metal detectors, to find a rich gold bearing specimens of ore. sometimes the best use of these minerals is to sell them at specimens.trapped in all this rock were veins of gold, typically in quartz. these veins were also pulverized down into small pieces in nugget, flake and flour size. because gold is so heavy, it settles to the bottom of our rivers, streams and any deep depression or crevice. this is where placer mining comes in.the extraction of gold by amalgamation and chlorination By ralph birrell university of melbourne he gold ores found above the waterline in the lachlan fold belt of south eastern australia in the were free milling, meaning that most of the gold could be easily separated from the quartz by crushing, followed by
