The following list outlines the problems experienced in the use of the conventional approach: • Differential froth flotation is very difficult because of the fine-grained nature of these mixed ores and therefore, ultra-fine grinding (with its associated costs) is required for the adequate liberation of the phases prior to the production of the individual concentrates (Frias et al., 2008).

Lead and Zinc - US Department of Energy

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.

FLOTATION OF ZINC OXIDE ORE USING CATIONIC AND …

method for the recovery of oxidized lead and zinc minerals from ores at present is flota-tion (Onal G. et al., 2005). The flotation of oxidized lead and zinc minerals, particularly zinc minerals, is much more difficult than the flotation of corresponding sulfide miner-als. Hexyl and amyl xanthates are capable of collecting smithsonite.
