This slurry (more properly called the pulp) of hydrophobic mineral-bearing ore and hydrophilic gangue is then introduced to a water bath which is aerated, creating bubbles. The hydrophobic grains of mineral-bearing ore escape the water by attaching to the air bubbles, which rise to the surface, forming a foam (more properly called a froth). The froth is removed and the …

effect of pulp density on gold flotation recovery

Feb 15, 2018 · The ore being treated has both free gold and gold associated with pyrite. Quite simply stated, if the pulp density is not maintained at 30% or higher by weight, it is very difficult to keep the coarser free gold into the froth phase. Copper sulfate is often used as an activator for promoting free gold flotation

May 05, 2016 · It is usually present as the sulphide, molybdenite, which is readily recovered in the copper flotation concentrate. Copper sulphide flotation concentrates may contain from 0.25 to 1.00% MoS2. When such ores are milled in large tonnages the amount of molybdenum present may be substantial. Practically all major copper producers now have molybdenum recovery systems. The Copper…
