Lead-zinc ore usually exists in the form of sulfide ores, such as sphalerite and galena. Flotation is the most commonly used method.. The lead-zinc ore processing solution is adjusted and used in combination according to ore characteristics, metal grade and other factors, such as gravity-flotation, magnetic-flotation, and gravity-magnetic-flotation, in order to achieve the best …

Silver, Lead & Zinc Flotation Circuit #2. The recovery of silver minerals occurring in a lead-zinc sulfide ore is efficiently accomplished using the above flowsheet. The process consists of selective flotation to produce a mixed silver-lead concentrate for maximum smelter return and a separate zinc concentrate.

Equal flotation process When a small part of galena has similar flotability to most sphalerite, it can use an equal flotation process. During the preferential flotation of lead, let an amount of the zinc minerals with good floatability float simultaneously, and float the remaining lead minerals at the same time as the flotation of zinc.

In addition, lead metal also has many uses in the nuclear industry, petroleum industry and other sectors. In the lead-zinc ore, there are 11 kinds of lead industrial minerals and 6 kinds of zinc industrial minerals, among which galena and sphalerite are the most important. Galena, sphalerite characteristics

Quartz and carbon carriers are added. The metal bath collects most of the lead, copper as well as silver and gold, if present. Zinc oxide is reduced, zinc evaporates and re-oxidizes in the off-gas. If indium is also part of the jarosite, it most likely follows the zinc into the dust. A simplified process scheme is shown in Fig. 2.
