Improve Copper Recovery – REXA, Inc. Electraulic™ Actuation

Background on Copper Recovery. Copper mining typically encompasses separating sulfide ore and recovery of purer metal particles from gangue minerals using froth flotation. The sulfide ore is then crushed, grinded and milled into fine particles. These fine particles then mix with water into a slurry, feeding into a flotation cell.

Improving the recovery of low grade coarse composite ...

Jul 01, 2011  The flotation behaviour of low grade, coarse composite particles for two porphyry copper ores was studied. Different grinding times were employed to obtain size distributions for the flotation feed (d 80) ranging from 150 to 320 μm.Copper containing particles in the fine to intermediate size ranges were recovered in the rougher flotation stage.

Magnetic conditioning of sulfide minerals to improve ...

In flotation practices, as particles become finer, such as smaller than 20 µm, process efficiency declines markedly. Selective agglomeration of fine particles is a technique to enhance the recovery of fine valuable minerals in flotation circuits. Different agglomerating methods have been introduced and tested. One method that has recently received much attention is to make use of magnetic ...
