Oil sands deposits that lie within 75 meters of the surface are typically recovered via mining. This process is much the same as strip mining for coal or any other mineral. Mining shovels remove the oil sand and load it into large mining trucks. These trucks carry the oil sands to mobile crushers. The crushed material is stockpiled for the next ...

The mining operation involves clearing the vegetation ahead of the area to be mined, stockpiling the topsoil for further use in the rehabilitation process. An additional 22 years of low grade stockpiles set aside during the mine life will be reclaimed and fed to the processing plant, extending the project life to 40years.

Ore is mined and processed at an onsite flotation processing plant capable of treating up to 24 million tonnes per annum (Mtpa). The plant currently recovers copper, gold and silver into a saleable concentrate. The primary ore is crushed and ground using Semi-Autogenous Grinding and Ball mills to a final grain size of approximately 180 microns.

Gold Mining Operation: 10 - 30 years. The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold. Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold.

The SX/EW Process. The SX/EW Process is a hydrometallurgical process since it operates at ambient temperatures and the copper is in either an aqueous environment or an organic environment during its processing until it is reduced to the metal. Because of its dependence on sulfuric acid, the SX/EW Process is at present not a substitute for, but ...
