Whether extracting alumina from bauxite, iron ore, phosphate, copper, titanium dioxide or coal, some generic applications like.

Vacuum Filtration

Liquid ring vacuum pumps are well known for cake dewatering on disc, drum, belt, and precoat filter applications.

Multiple Effect Evaporators

The final effect is typically under vacuum. Liquid ring vacuum pumps are used to remove the non-condensibles in order to maintain the proper vacuum level in this effect.

Waste Gas Recovery

Liquid ring vacuum compressors are used to recover CO and other waste gases produced in smelting and other similar operations.

Methane Gas Extraction

Methane gas accumulation in underground coal mining is dangerous. Explosions and resultant loss of life can and has occurred.
