Study on Flotation Technology of Refractory Oxide Lead-zinc Ore in Huize

摘要

Huize oxidized lead-zinc ore contains 1.53% Pb, 16.67% Zn, and the oxidation rate of lead reaches up to 95.07%, zinc is 85.27%, belongs to high-zinc but low-lead oxidized lead-zinc ore. According to the characters of ore, the technology that lead prior to zinc and desliming in oxidized zinc flotation has been adopted, as well as combined modifiers, ideal performance that grade and recovery of lead concentrate reaching to 51.61% and 62.54% respectively, and zinc concentrate reaching to 38.90% and 70.22% respectively has been obtained.
