A study was performed to characterize the Ishiagu lead-zinc deposit prior to beneficiation. The study included the use of XRD, SEM and both reflected- and transmitted-light microscopy. The results showed that the ore consists mainly of galena (PbS), sphalerite (ZnS) and quartz (chert), with pyrite, siderite and chalcopyrite occurring as trace …
Depletion of high-grade ore deposits has continued to place pressure on the mining industry to find new ways of effectively processing lower-grade and complex ores. This thus calls for the development and optimization of such beneficiation techniques to enhance the recovery of such ores in valuable metals [3]. This study addresses the need …
