Lead: smelting, producing and classification-Metalpedia

First of all, the ore must be concentrated to separate the lead ore from the zinc ore, for example. It turns out to be possible to do this with flotation. A substance is added that wets the zinc ore, allowing it to sink to the bottom, but does not wet the galena, allowing it to be caught up in a

Copper Lead Concentrate Separation

2015-10-1  The separation of copper-bearing from zinc sulphides is effected by two-stage selective flotation, the zinc minerals being depressed and the copper minerals brought up in the first stage with reagents similar to those required in the lead flotation section of a lead-zinc plant; the zinc sulphides are floated in the second stage in the ordinary way. The ores treated by this process are mainly those

2020-6-19  All was not solved, however, for two problems persisted. Froth flotation was still unable to separate zinc from silver-lead conglomerates. Thus when the process was applied to newly-mined ore, unseparated concentrations of lead and zinc were produced. This lead to further developments in the Mineral Separation Process. F. J.

Extraction of Zinc Application Of Zinc Refining Process

Zinc Blende does not contain a very high percentage of zinc and hence it needs to be concentrated. The best concentration method for zinc ore is known as froth flotation. Concentration of Ore: Froth Flotation Process. Froth Flotation process is mainly used to remove gangue from sulphide ores. The ore is powdered and a suspension is created in water.

zinc processing - Ores Britannica

The mineral particles cling to the bubbles and float to the surface, forming an oily froth that is constantly skimmed, while the gangue is wetted by the action of the chemicals and sinks in the cell. The proper choice of frothing agents makes it possible to separate each constituent mineral of complex lead and zinc
