The Flotation Concentration of a Complex Low-Grade Lead Zinc Ore

摘要

This report is concerned primarily with the beneficiation of a low-grade complex lead-zinc ore. The depletion of high grade veins has caused the mineral engineer to seek deposits deeper in the earthu27s crust or to find lower grade deposits. The other alternative has placed more research problems on Mineral Dressing Engineers in particularly the iron, copper, lead and zinc fields.
