Flotation of Aladagˇ oxide lead–zinc ores - ScienceDirect

2005-2-1  1. Introduction. In practice, the commonly used method for the recovery of oxidized lead and zinc minerals from ores at present is flotation (Caproni et al., 1979; Ciccu et al., 1979; Önal and Abramov, 2002; Pereira and Peres, 2004; Dashti et al., 2004).The degree of oxidation in lead ores may range from slight tarnishing of the galena to complete oxidation.

2019-12-27  This study presents the recovery of oxide-carbonate lead-zinc ores using different chemical reagents under different test conditions by flotation. The run-of-mine oxide-carbonate Pb-Zn ore contains 9.05% Pb and 11.97% Zn with a major mineralization of smithsonite and cerussite. First experimental work was grinding tests to reduce -106 μm size fractions with two 15-minute grinding stages.

The pre-treatment of zinc oxide bearing ores with high slime content is important to ensure that resources are utilized optimally. This paper reports an improved process using hydrocyclone de-sliming, dispersion reagents, and magnetic removal of iron minerals for the pre-treatment of zinc oxide ore with a high slime and iron content, and the benefits compared to traditional technologies are shown.
