Mineral processing Wikipedia

Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.

Gravity Separation an overview ScienceDirect Topics

Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.

Advanced utilization of copper in waste printed circuit

The physical separation scheme of "gravity separation-grinding-flotation" is proposed to pre-concentration the copper in the WPCBs, which can increase the grade of copper from 16.22 % to 72.62 %. Then, the ammonia/ammonium salt leaching process is raised to leach the copper from the flotation copper concentrate.
