Mining and Metals
Mining and Metals In open pit / open cast mining, overburden material (soil and surface rock) is stripped and stockpiled. The mineralised zone is then mined preferentially although ongoing removal of waste rock will typically continue to some extent throughout the life of mine. Open pit / open cast mining employs relatively
Gold Processing | Equipment, Process Flow, Cases
· 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.

Stoping
Stoping is the process of extracting the desired ore or other mineral from an underground mine, leaving behind an open space known as a stope. Stoping is used when the country rock is sufficiently strong not to collapse into the stope, although in most cases artificial support is also provided.. The earliest forms of stoping were conducted with hand tools or by firesetting; .
Use of Rock Crushers in Gold Mining
· Jew crushers are designed to be heavy duty machines used as the primary crushers in many mining operations. Because of this, the crushers are robustly constructed.
