Lead and zinc ores flotation

Aug 09, 2021

Aug 23, 2021 Compared with lead-zinc oxide ore, the composition of lead-zinc oxide ore is more complex, with many associated minerals, and the particle size is finer. It is easy to produce sludge and contains a lot of soluble salts. Various reasons make the flotation treatment of lead-zinc oxide ore difficult
