How a Thickener Works

One tall thickener thus does the work of several relatively shallow thickeners of the same diameter. Floor space is conserved, heat insulation is simple and effective, and power is reduced. Furthermore, all control of the washing operation is centered at a single point. Cyanidation and concentration of gold and silver ores

Pressure Oxidation

Pressure Oxidation (POX) is a process used to extract gold, copper, zinc, molybdenum, and uranium from refractory ore bodies. The POX process utilizes elevated temperatures (roughly …

Pressure Oxidation

Overview. Pressure Oxidation (POX) is a process used to extract gold, copper, zinc, molybdenum, and uranium from refractory ore bodies. The POX process utilizes elevated temperatures (roughly 230 degrees Celsius), elevated pressures (roughly 35 bar or 510 psi), and oxygen to liberate the minerals from refractory ores.

Zinc Powder Replacement Plant Solution

The zinc powder replacement process is to mix the zinc powder with the gold containing solution, precipitate the gold after being replaced by zinc, and then filter. The gold powder and excess zinc powder enter the filter cake (i.e. cyaniding gold mud) and are separated from the liquid after gold removal.

3 Common Problems and Solutions of Mining Thickeners

Thickener is a solid-liquid separation equipment based on gravity sedimentation, which is the commonly used thickening equipment in beneficiation plants. In actual production, most mineral processing plants will encounter various thickener problems, which will not only affect the normal operation of mineral beneficiation, but also seriously damage the economic …
