Mineral Processing Scientific Research on a Gold-Bearing Polymetallic
In this article amalgamation flotation combined flowsheet and adaptable technology additions was adopted basing on the full demonstration and experimental study,in addition of head grade:Au 7.18 g/t,Ag47.7 g/t, Cu 0.207%,experiment index:flotation bulk concentrate contain Au 54.00 g/t,Ag 509.0 g/t,Cu3.13%,the recovery of Au Ag Cu was 90.53%?95.98?97.67;full mud cyanide leaching:Au leaching rate is 84.60%?Ag leaching rate is 78.60%.
FIELD: foundry, namely casting method with use of casting mold having consumable model. SUBSTANCE: method comprises steps of producing porous powdered part of non-evaporated powder; manufacture of casting mold with use of porous powdered part as consumable model; casting melt metal to prepared casting mold. At casting process porous powdered part practically completely breaks and powder being partially material of part becomes component of cast article. EFFECT: simplified process of casting articles of complex shape and complex inner structure without using inserts. 38 cl, 2 dwg, 1 ex
