Zn Pb Strength Sandball Mill

Clean production of sustainable backfill

· Behera et al (2020a) used lead zinc mill tailings and slag as paste backfill materials using slag as a partial replacement of cement The study developed an environmentally friendly paste backfill material for underground mines The ratio of ordinary Portland cement of up to 8 was investigated They reported a minimum unconfined compressive strength of MPa at 7 days curing and MPa

was sphalerite (Typically 10 to 11 Zn) with some minor galena ( Pb) in a dolomite (Magnesium Carbonate) host rock The only other competing sulphide mineral was pyrite (Circa 3 to 5 Fe in Mill Feed This CW ore type predominated the first 6 years of production but in August 2002 the ore mineralogy changed due to significantly

Environmental Benign Brass Alloys Dispersed with Graphite

Sintered Cu 40mass Zn (brass) alloys with a high tensile strength and excellent machinability have been developed via a powder metallurgy (P/M) process They are environmentally benign because fine graphite particles are included instead of lead (Pb) to improve their machinability The effect of the content and particle size of the graphite on the mechanical properties and machinability are
