J.F. Cameron, C.G. Clayton, in Radioisotope Instruments, 1971 Density gauge applications. Accurate control of density and flow rate is important in almost every form of milling, whether it be gravity concentration, flotation or leaching.In concentration methods using gravity, a steady uniform rate of feed is essential for efficient operation of all types of tables, jigs, and spirals.

Gravity methods use the difference in the density of minerals as the concentrating agent. In heavy-media separation (also called sink-and-float separation), the medium used is a suspension in water of a finely ground heavy mineral (such as magnetite or arsenopyrite) or technical product (such as ferrosilicon).

For many gold copper ores production of a gravity concentrate from the mill circuit results in the recovery of much of the gold or copper into a relatively small stream. The remaining material can then be economically treated to recover the remaining minerals; generally by CIP or flotation. The incentives to do this vary depending on the ore and

Gravity concentration. Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal forces, magnetic forces, buoyant forces), one of which is resistance to motion (drag force) by a viscous medium such as ...

The mill has a gravity recovery circuit comprising one 30 inch Knelson treating screened cyclone underflow. This produces a high grade gold concentrate containing 1 to 4% gold and 5 to 7% copper, which is upgraded on a table with recoveries of about 70%. This gravity circuit recovers about 50% of gold in feed.

Gold was subjected to the gravity concentration device in its coarsest state, i.e., as soon as a particle was discharged from the mill it saw the gravity concentration device. There were also some disadvantages: The gravity circuit had to process 3 or 4 times the new feed rate to the mill (the entire circulating load).
