sphalerite, galena, tetrahedrite, barite and quartz. Pyrite, being the most prevailing mineral of the sulphide ore, is intergrown with all other mineral components. Therefore, it is not possible to extract lead, zinc and copper minerals from complex sulphide-barite ore by flotation process. Leaching tests

On the other hand, barite flotation tests, mostly, did not yield to barite concentrates in conformity with the high industrial quality requirements; this can be explained by the carbonated gangue. However, barite recovery generated a tailing of only 17% barite, which will reduce the contamination of the surrounding environment by the barium ...

The flotation behavior and separation mechanism of bastnaesite from barite and calcite were evacuated by micro-flotation, zeta potential measurements, FTIR spectra, XPS detection and DFT calculation. Micro-flotation results revealed that OBHA exhibited superior collecting ability to bastnaesite but did not float calcite and barite.

Srdjan M. Bulatovic, in Handbook of Flotation Reagents: Chemistry, Theory and Practice, 2010 Treatment of mixed lead zinc sulphide oxide ores with barite–calcite gangue minerals. There are only few operations treating mixed lead zinc sulphide oxide ores that contain barite –calcite gangue minerals. A typical example of such an operation is the Tynagh oxide complex in Ireland [11].

Sequential Copper–Lead–Zinc Flotation. To improve the selectivity between copper and lead, a sequential copper-lead-zinc rougher circuit was tested. Each of the rougher circuits had a dedicated regrind and cleaner circuit. The advantages of the sequential circuits are that the levels of selectivity can be increased, particularly for copper ...
