Why high-rate thickeners are now preferred by the gold

May 01, 1990 The two-stage thickener configuration results in recovery of 65% of the residual cyanide. Flotation Tailings. At the Fimiston gold treatment plant in Kalgoorlie, the ore is subjected to flotation and the tailings are then leached in cyanide for gold recovery. (The concentrate is sent to the Gidgee site for roasting and leaching of the calcine).

How a Thickener Works

Jul 13, 2016 How a Thickener Works. Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle

Mineral processing Wikipedia

After thickening, slurry is often stored in ponds or impoundments. Alternatively, it can pumped into a belt press or membrane filter press to recycle process water and create stackable, dry filter cake, or "tailings". Thermal drying is usually used for fine particles and to remove low water content in the particles.
