Lead-Zinc Flotation at North Broken Hill Limietd
Present practice of lead-zinc flotation at North Broken Hill Limited is described and factors influencing plant objectives and performance discussed. Mineralogical examination of final flot- ation products showed mineral liberation to be 94T complete and size by size metal recovery tables indicated a need for finer grinding to improve lead and silver recovery, but coarser grinding to improve zinc recovery. A steady grinding circuit, at constant ball mill power and cyclone overflow pulp density, is found desirable for satisfactory flotation circuit operation because instabil- ity in the grinding circuit inevitably leads to flotation instability and as a consequence less than optimal flotation operation. Remov- al of the variable lead flotation middling product from the grinding circuit decreased grinding instability.
