Effect of density of pulp and size of particle on biooxidation of a polymetallic concentration in the southern sector of Ecuador

摘要：

Poor technology used for recovery of refractory gold is generating social and environmental problems in Ecuador. Thus, bioleaching offers a sustainable and economic alternative as a pretreatment for a better and more complete recovery of gold. The aim of this study was to determine the optimal values of particle size and concentration of pulp in order to enhance the kinetics of bioleaching of gold tailings concentrate of two areas of southern Ecuador ( Portovelo and Bella Rica) using native consortium of acidophil microorganisms in which one was
