lead zinc sequential flotation

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

Lead Zinc Sulfide Separation by Sequential Flotation

In the majority of the zinc operations, sphalerite (ZnS) is associated with galena and often sulfides of iron and copper. It is therefore essential to arrange the flowsheet not only for recovery of the valuable minerals, but also to selectively separate them into products acceptable to the smelters for ultimate conversion into metal. The flowsheet outlined above is typical for the average

Lead-Zinc ores Danafloat

The established lead-zinc ore flotation processing scheme is to add zinc sulphate (ZnSO4) to the grind to control metal ion activation (sphalerite depression). Often metabisulphide or other sulphidation chemicals are added with the zinc sulphate for iron sulphide mineral depression.
