chalcopyrite flotation screen

CA2765926C

The invention relates to a method for leaching bulk concentrate of chalcopyrite-type by means of an aqueous solution containing sulphuric acid and an oxygen feed at atmospheric pressure and at a temperature between 750C and the boiling point of the solution. It is typical of the method that the particle size of the concentrate to be fed into leaching is in the region of 80 % below 60 - 100 m

copper ore flotation cell py series

Analysis of the flotation behavior of complex copper ore. Flotation tests were conducted on a Chilean copper ore containing chalcocite, bornite, and chalcopyrite using a Denver-type flotation cell at 0, 50, 100 g/t NaHS and pH 8, 9, 10. At several points in the flotation tests, solutions were sampled for analysis of S ion in the solutions. get

Copper Processing

A trommel screen is used to remove scats and oversize material that could damage the pumps and the classification cyclones. Finer particles that are below the cut point – the overflow – are transferred for primary flotation. The underflow is sent to a secondary ball mill and trommel screen, for additional grinding and classification.

Flotation Machines

Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.

Evaluating the sulphidisation and flotation of oxidised

The controlled potential sulphidisation process, which has been widely applied and shown great potential as a remediation strategy for flotation of oxidised copper sulphides, still suffers from drawbacks such as low efficiency and difficulty to restore floatability of heavily oxidised sulphides. This study sought to understand the surface reactions of sulphidisation on oxidised chalcopyrite.
