Froth Flotation for zinc ores with example - Zinc Processing

08/12/2019  Froth flotation for zinc ores allows us to separate zinc bearing minerals from gangue, also from lead, copper, as well as pyrite. The usual grade of zinc ores is between 4% and 20% of Zn. After flotation concentrates contain 40-60% Zn. The zinc flotation concentrate is not chemically processed; it remains in the form of sulfide or oxide. Zinc concentrate is prepared by hydrometallurgy and ...

Similar to copper-zinc and lead-zinc ores, copper-lead-zinc ores have several major geological formations, of which the most important are: Deposits that occur in hydrothermal vein fillings and replacement (usually of limestone) bodies, often associated with intermediate to acid intrusions. These ores contain silver and gold in addition to copper, lead and zinc. Such deposits are found in North

Copper-Lead-Zinc ores - Danafloat

Therefore the standard Cu-Pb-Zn flotation practice involves an initial flotation of a Cu-Pb bulk concentrate followed by two parallel circuit stages of copper-lead separation and separate zinc flotation from the bulk flotation tails. As described in the lead-zinc ore processing section, zinc sulphate and metabisulphide sphalerite and pyrite depressants, respectively, are typically added to grinding. Then a Cu-Pb bulk

Frothers - an overview ScienceDirect Topics

The function of the frother is to generate a foam layer at the top of the flotation cell for ink removal. A frother must be used to obtain a stable foam layer to remove ink particles. Non-ionic surfactants are widely used as frothers in flotation deinking because they have excellent foamability and function independently of water hardness.
