Sequential CopperLeadZinc Flotation

To improve the selectivity between copper and lead, a sequential copper-lead-zinc rougher circuit was tested. Each of the rougher circuits had a dedicated regrind and cleaner circuit. The advantages of the sequential circuits are that the levels of selectivity can be increased, particularly for copper and lead. With this process, copper was recovered first with MBS depression of lead, zinc and ...

Froth flotation of Aljustrel sulphide complex ore

Abstract: Froth flotation of copper-zinc-lead ores is a complex process based on similar metallurgy processing and strong interactions between chalcopyrite and sphalerite. These types of ores represent 15% of the world production and 7.5% of copper deposits all over the world. In the present study, an attempt is

In order to obtain best results, operation parameters were optimized. Besides, the number of cleaning and scavenging stages of zinc circuit was reduced by using column flotation instead of mechanical flotation. Hence, higher grade zinc concentrates with higher recovery were obtained. Using three stages of cleaning and three stages of scavenging, the zinc concentrate having 58.81% Zn was produced with a recovery of 74.21% indicating an improvement in final zinc concentrate.
