Chemometric Optimisation of a Copper Sulphide Tailings

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 …

2.4 Copper Layer Thickening Conditions. A set of copper layer thickening method: When magnetron-sputtered copper plating thickens, the sputtering copper plating time is increased while keeping the sputtering parameters unchanged. At the end of magnetron sputtering, the vacuum chamber temperature was measured to be around 220 °C.

How a Thickener Works

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.

Understanding the Thickening Process

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.
