Gold processing - Mining and concentrating Britannica

Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...

Mining Techniques of the Sierra Nevada and Gold Country

Hydraulic mining was a variation on ground sluicing where the water delivered to the site would be shot through a nozzle at high pressure onto the face of the cliff, thereby washing away tons of boulders, gravel, dirt, and gold. The first use of this method is credited to Edward Mattison in 1853. Mattison delivered the water through a rawhide hose to a nozzle he carved out of wood. Later ...
