Mineral processing

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.

Abstract The radioactive tracer technique was used to measure the Residence Time Distribution (RTD) of the liquid and solid in a rougher flotation bank consisting of seven cells of a volume of 130 m. Thus, a pneumatic system of high reliability was used in order to introduce a small amount of radioactive tracer (around 100 mL of liquid or
