Vale opens plant to make mining waste into construction

The plant will offer a sustainable material for construction products as an alternative to sand, a highly demanded resource. Tailings are a waste product of ore processing a slurry of fine uneconomic rock and chemical effluent and Vale’s new plant will enable it to redirect waste that would otherwise be disposed of in storage

Waste & Ore Pass Design @ Underground Transfer Points

Ore passes are simply vertical or inclined openings for transfer of broken ore to the haulage system. They may be raises in the ore or in the walls of the deposit or timbered openings through filled stopes and, as previously stated, usually terminate at the bottom in some form of loading chute. They must be steep enough to insure that the ore will run freely and usually are inclined at angles
