4. Bulk (Copper-Moly) Thickener. A high-rate thickener dewaters the bulk of copper-moly concentrate before more separation. 5. Moly Flotation. The moly flotation circuit has similar groups of flotation cells with chemicals to float the molybdenite (moly concentrate), and settle out the copper sulfides (copper concentrate). 6.

For good dewatering, you always need a pressure filter after thickening. The Dorr traction thickener is the type most frequently used for heavy- duty work with large tonnages. The machine is so called because the thickening mechanism is driven by means of a traction wheel which travels around the periphery of the tank on a rail.

The SART (sulfidization, acidification, recycling, and thickening) process (SP) has been successfully implemented in gold cyanidation plants to address issues associated with high cyanide-soluble copper content ores. However, this process could produce a relatively low grade precipitate, decreasing the sale price when gold plants have high zinc and copper content in …

Furthermore, the thickening stage can be optimized by fixing a recycling criterion, depending on the copper concentration in the feed solution of the SART process. Accordingly, it is possible to establish that there are promising results in reducing the thickeners size, due to the use of higher settling rate in the design, avoiding or reducing ...

At the heart of most of the copper tailings thickening processes is particle flocculation. Aqueous solutions of flocculants (long chains of water-soluble polymers) are added to bridge the fine particles into large, fast-settling aggregates, with the aim of producing a clear liquor (overflow) and also a concentrated slurry (underflow); the latter is typically pumped out from …

Abstract: The thickening process is the primary method of producing high solids slurries for the minerals industry. Thickener outputs can accommodate a range of tailings disposal options from low yield stress, easily pumped suspensions for disposal in conventional 'wet' tailings dams to more concentrated slurries for delivery to 'dry disposal' and backfill applications.
