Selective passivation behavior of galena surface by sulfuric …

The bulk flotation of copper-lead sulfide ore in the first stage is easy because both chalcopyrite and galena have better natural floatability than other sulfide ores, and this is also an important reason for saving reagents. However, the difficulties of copper-lead mixed flotation are related to the separation of copper lead mixed concentrate.

The chromate or dichromate is effective and widely used in depressing galena in the flotation separation of copper-lead sulfide ores. However, dichromate is known to be carcinogenic to humans and carries a high risk of environmental pollution (Hu et al., 2020). It is more and more imperative to develop chromium-free depressants for the ...

How to Separate Copper from Lead by Cu Depression

To achieve this copper/lead separation, bulk flotation is performed with depressants to control sphalerite and pyrite. Cyanide was used in the bulk rougher as it will also be used in the reverse. Rougher testing indicated that 10 to 50 g/tonne cyanide in the bulk rougher was sufficient. The bulk concentrate was then subjected to relatively high ...

The Pb content in the copper concentrate was as low as 12.21%, which was quite similar with that using K 2 Cr 2 O 4 as depressant. Through the comparison of two groups of test results, it demonstrated that the combined depressants H 2 O 2-NaHA could be a potential substitute of dichromate in copper-lead flotation separation.
