Silver Lead Zinc Ore Processing Method using Flotation

Sulphide ore of lead and zinc containing considerable silver was submitted for testing with the purpose of determining a flowsheet for the production of separate lead and zinc concentrates for marketing at their respective smelters. It is necessary to recover as much silver as possible in the lead concentrate as a higher return for this silver is realized than for the silver in the zinc

How to Process Oxidized Lead-Zinc Ore by Flotation

The ore for treatment is a lead-zinc carbonate ore in a mixed siliceous-lime carbonate gangue. The association of the minerals and gangue requires a 65 mesh grind for liberation. The problem is to produce marketable grades of lead and zinc concentrates. The Flowsheet. This flowsheet was developed from an exhaustive study of the minerals involved. Many theories were explored to answer the
