· Background. Hydraulic fracturing involves producing and extending fractures in rock by injecting a fluid under pressure into a section of a borehole. The fluid pressure produces tensile stress in the rock at the borehole wall, causing a fracture to start. The fluid then enters the fracture and opens and extends it deep into the rock.

Concentration of Ores. An ore of a metal is an impure source, this means other than the metal it consists of many other impurities such as sand, grit, clay, rocks etc. These impurities are collectively known as gangue.
