Recovery of noble metals from floor sweeping jewelry

2020-1-28  The particle size has a great effect on gold recovery due to its high specific density. For effective flotation of gold particles, the range of 20–200 μm is generally preferred. At grain sizes less than 20 μm, the selectivity decreases due to a large amount of floating tailings.

The interaction of lignosulfonate dispersants and grinding

2013-9-1  Fig. 8 shows cumulative copper, gold and mass recovery as a function of water recovery in the flotation of the high clay ore with and without the presence of F-100 dispersant when the ore was ground using mild steel grinding media. At the end of flotation, copper, gold, mass and water recovery was 36%, 51%, 8% and 21%, respectively, with the

The role of a flash flotation circuit in an industrial

When the flash flotation circuit is taken off-line the recovery of sulphur (and hence pyrite) is observed to decrease dramatically, and whilst the recovery of gold also decreases, it is to a much lesser extent. The difference in the recoveries of gold and pyrite that is observed without the flash flotation circuit in operation is most likely
