The Broken Hill silver-lead-zinc ores are probably the most famous in Australia, and have particular significance in mineral processing as it is these sulphide ores which provided the impetus (in the early part of last century) to develop an industrial flotation practice.

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 and lead. With this process, copper was recovered first with MBS depression of lead, zinc and ...

lead and zinc flotation process - epicarmoury.co.za. Froth flotation is considered to be the most widely used method for ore beneficiation.

Classified slurry from the grinding circuit is dewatered in a flotation feed thickener from where feeds a three stage copper–lead–zinc sequential flotation circuit. The copper flotation section produces a copper concentrate through two stages of flotation as shown in Fig. 1. Flotation reagents are added through the conditioning tank, TKF2.

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Evaluation of tailings from processing plants is always an important issue. Lead-Zinc ore tailings containing 3.12% Zn, 3.43% Pb, 0.71 g/t Au and 74 g/t Ag was subject to this study.

Froth flotation is a very important mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper, lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potash.

Three methods of improving zinc concentrate grade in the flotation of two massive sulphide ores were investigated. These methods involve the use of oxygen gas conditioning, copper specific collectors or selective polymeric depressants.

As an example of the beneficial effect of copper sulfate in the activation of zinc sphalerite toward flotation, the series of results shown in Fig. 1 is of interest. These represent rougher tests on a sample of heavy pyritic ore. The particular sample in question contained about 5.6% zinc as marmatite; and was treated in a circuit made alkaline with lime, using pine oil as a frother and ...

Gold recovery from copper– zinc ores is usually higher than that obtained from either a lead–zinc or copper–lead–zinc ore. This is attributed to two main factors. When selecting a reagent scheme for treatment of copper–zinc ores, there are more choices than for the other ore types, which can lead to the selection of a reagent scheme which is more favourable for gold flotation.
