The purity of water used in flotation work may have a very important effect on the results to be obtained; in these experiments ordinary

16/05/2016· Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more parallel grinding and flotation circuits. For additional capacity,

Can you list the factors affects the floatability of pyrite from refractory low grade ore. I used a Wemco lab flotation cell and aimed on analysing factors like collector dosages (PAX), Activator (Copper sulphate),MIBC , pH and others like pulp density and particle size (70 and 150 microns) .However how these factors affect the floatability of the pyrites from low grade refractory ore.

28/10/2021· The main factors affecting the flotation of copper-bearing pyrite: Disseminated grain size and symbiotic relationship of copper and iron sulfide. Generally, pyrite has a coarse grain size, while copper ore, especially secondary copper sulfide, is closely associated with pyrite. Only when the copper ore is finely ground can it be dissociated from pyrite. This

23/08/2019· Copper sulfide ore flotation Copper sulfide ore classification (1) Single copper ore. Its composition is relatively simple, and the only valuable component is copper. The gangue is mainly quartz, silicates, and carbonates. (2) Copper-sulfur ore. valuable components are copper, pyrite. (3) Copper pyrite. valuable components are copper, pyrite,

Experimental studies have been carried out with Denver flotation machines using,Role of starch and metabisulphite on pure pyrite and pyritic copper ore flotation 43 occurred with 1.7 mg/ dm3, while 21% depression occurred with the same dosages of starch at pH 6.5 where pyrite flotation is expected to be weak at pH 10. This can be explained as because starch adsorbed
