Pb-Zn Mineral Processing

About Pb-Cu. Lead and zinc are extremely close in nature, especially in primary deposits, and often coexist. Most of the lead-zinc minerals are sulfides and sulfates, and galena and sphalerite are the primary Pb-Zn ores. Non-sulfide: It is formed due to hypogene and supergene weathering. Mostly oxide ores like zincite, and cerussite may fall under this category.

Distribution of Sb minerals in the Cu and Zn flotation of …

Flotation tests on Rockliden composite samples have shown that the threshold of 0.2 wt% Sb is exceeded in the Cu–Pb concentrate even if the Sb grade of the blended feed material is below this value (Bolin, 2010, Minz, 2013).This is related not only to the flotation behaviour of common Sb minerals but also to the mineral association and the degree of …


Selective depression of sphalerite by chitosan in differential Pb Zn

Chitosan was exploited as a selective depressant in the differential Pb Zn sulfide flotation at pH 4 on artificial galena and sphalerite mixtures. The mixtures were prepared in two different approaches. In the first approach, the high purity galena and sphalerite were blended directly whereas in the second approach, the sphalerite was coated with copper before …
