Borax method

Borax method

History. The borax method of gold extraction has been used by artisanal gold miners in the Benguet area north of Manila in the Philippines for more than 30 years. Some believe it was in practice as early as the 1900s. The method is increasingly being seen as a safe alternative to the widespread use of toxic mercury in artisanal gold mining today.

Oil Sands Extraction and Processing

Oil Sands Extraction and Processing

Insitu extraction methods are used to recover bitumen that lies too deep beneath the surface for mining (greater than 75 metres underground). Currently, 80% of oil sands reserves are accessible via insitu techniques. Steam Assisted Gravity Drainage (SAGD) is currently the most widely used insitu recovery method.
