Setting up your wash operation for success
Washing and classifying of aggregate can be considered in two parts, depending on the size range of material: 1. Coarse material. Generally above 3/8 in. (and sometimes split at 1/4 in. or #4 mesh). In the washing process, it usually is desired to remove foreign, objectionable material –including fine particles. 2.

12.10: Open-Pit Mining
12.10: Open-Pit Mining. Open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of ...
Open Pit Uranium Mining
In open pit mining, overburden is removed by drilling and blasting to expose the ore body, which is then mined by blasting and excavation using loaders and dump trucks. Open pit mines require large holes on the surface, larger than the size of the ore deposit, since the pit's walls must be sloped to prevent collapse. In 2012, the percentage ...
