16/06/2017· Thickening is a process where a slurry or solid liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water . The driving force for the separation is gravitational, where the differences in phase densities drive the separation of the solids and liquid.
Copper extraction refers to the methods used to obtain copper from its ores The conversion of copper consists of a series of physical and electrochemical processes Methods have evolved and vary with country depending on the ore source local environmental regulations and other factors As in all mining operations the ore must usually be beneficiated The processing
The mineralogical properties of the ores are increasingly influencing the required processing methods. In the production of copper, sulfidic ores are enriched into concentrates by grinding and flotation, followed by pyrometallurgical processes for the production of pure copper. Oxidic ores are treated with sulfuric acid in a heap leaching process after the grinding stage and are

29/10/2019· Since the first successful use of deep cone thickener to achieve high concentration tailings discharge in the Kidd Creek copper zinc mine in Canada in 1973, the use of deep cone concentrators for concentrated tailings storage has been around for more than 30 years in the world. Development is by technology and promoted and applied locally.
the thickener. WesTechs EvenFloTM design consists of a two part feedwell system. An inner chamber converts the feed energy into a concentric radial flow for optimal mixing of flocculent and solids in all areas of the main chamber. The main feedwell chamber then evenly distributes the feed into the sedimentation zone of the thickener.
