modifiers for copper lead zinc ores flotation

Mineral Processing Technology | Engineering at Alberta

Tailored grinding aids for individual mineral and ore systems that modify slurry rheology and assist in ultra-fine particle dispersion during grinding; Specific collectors and modifiers for efficient flotation separation of base metal sulphide ores (such as lead-zinc, copper-lead-zinc and copper-nickel) in ultra-fine particle size range.

Flotation Reagents' Types and Working Principles | CNFREEFor example, in the flotation of lead-zinc sulfide ore, it is necessary to separate lead, zinc and sulfur. At this time, flotation reagents are used to change the nature of one of the minerals and separate them one by one. In the case of lead-zinc separation, the "zinc-inhibited and lead

Effect of Water Composition on Flotation of Lead and Zinc

Copper 0.0022 ppm 0.0091 ppm 0.0160 ppm 0.0022 ppm 0.0045 ppm Zinc 0 In order to investigate the effect of water composition on lead and zinc flotation, the ore sample subjected

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

An eg. of the Cu-Zn system can be considered to understand the action of a Depressant, The Cu ions present in the mineral leads to unintetional activation of the Sphalerite (i.e. Zn mineral

INTERPRETATION OF FLOTATION DATA FOR THE DESIGN OF Separation may be a simple bulk float (i.e.pyritic gold ores, some copper ore with negligible pyrite) or as is the case for polymetallic ores, a complex three stage sequential separation (ie copper, lead, zinc).

Cu-Pb-Zn, Copper-Lead-Zinc Ores, Copper Lead Zinc In general, the most difficulty of the polymetallic sulfide ores separation is the separation among several kinds of ores, especially those low-graded ores with complex embedded features. Therefore, it's a significant step for separating lead-zinc, copper-zinc, copper-lead to choose right flotation reagents.

Flotation | ore dressing | BritannicaFlotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

The major sulphide minerals in the ore are chalcopyrite, galena, sphalerite, marmatite and pyrite with corresponding metal amounts of 6.80% Pb, 1.05% Cu and 1.50% Zn, respectively. The ore sample was ground to below 200 ?m and then collective and selective sulphide flotation
