Froth flotation of oxidized zinc ores Internat,

The tailing from the second flotation operation was subjected to third and fourth flotation operations each designed to produce an oxide-zinc concentrate. The reagents used were as follows: 0.36 pound per ton of potassium ethyl xanthate and 0.25 pound per ton of pentasol amyl xanthate were incorporated in the ore pulp during grinding.

Study on the pre-treatment of oxidized zinc ore prior

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-s, 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.
