Sequential Copper–Lead–Zinc Flotation

2021-3-10  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

Recovery of lead, zinc and iron sulfide - The Anaconda

Lead sulfide (galena) is usually found in association with iron sulfide (pyrite), and often with zinc sulfide (sphalerite). The conventional procedure for treating ores of such composition is by selective froth flotation, to obtain lead in the form of a high grade lead concentrate and zinc in the form of a high grade zinc concentrate.
