Gold mine tailings, the treasure place of recovery gold ...

In mining, when flotation is finished with the ore, and a final concentrate has been produced, often, both products will go to a concentrate thickener before it is dried for shipping. This is a very important step so here we discuss Basic Concentrate Thickener Operation. For the mine to get its concentrate to the smelter it will have to be transported, by truck, train or ship. To illustrate ...

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 as long as required, the top liquid was decanted, the settled solids were ...

Forgotten Gold – Searching Abandoned Mines and Tailings

Abstract: The operational fluctuations of tailings thickeners have the potential to cause significant impacts on the tailings transport system and the tailings deposition at a tailings storage facility (TSF). The statistical analysis of actual recorded data of underflow solids concentration and flowrate of different thickeners is presented in this paper.

The use of High Rate Thickeners has gained wide acceptance in the mineral treatment industries. The design of these units is characterized by an efficient deaeration and flocculation chamber, and introduction of the flocculated feed solids into a preformed floc bed zone. By these means the settling process is accelerated and consequently High Rate Thickeners...
