1 Lead-zinc sulfide ore 1. Beneficiation process of lead-zinc sulfide ore: The main constituent minerals of lead sulphide ore are galena and sphalerite, all of which are primary ore. Galena has good floatability. In most lead-zinc mines, zinc is higher than lead. Most of the lead-zinc sulfide mine uses preferential flotation technology

22.4: Beneficiation. Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of

lead processing - lead processing - Mining and concentrating: Once the ore is removed from veins (narrow channels) or lodes (roughly spherical deposits) in the Earth, usually at depths of about 60 metres, the ore is treated at concentrating mills. Here the ore is finely crushed, sometimes to particle diameters of less than 0.1 millimetre (0.004 inch), and then treated by one of several mineral

6.1 Process Overview 6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

Treatment of oxidized lead ores (Cerussite) has long been recognized as a difficult process often resulting in low grade concentrates and low recoveries. Surface oxidation on galena ores has resulted in high tailings losses. The difficulty in treating oxidized lead ores by gravity methods is due to the softness of the oxidized lead minerals.
