The feasibility of processing low-grade copper-nickel ores by heap bioleaching was investigated. It found that an iron-oxidizing strain acidophilic microorganisms, Acidithiobacillus ferrivorans, is effective in the leaching sulfide from deposits Russia’s Murmansk region. Sulfide mineralization studied mineral feeds described using methods X-ray phase analysis and optical microscopy. In process ...

Post-mineralization activities may cause difficulties in the process of ore modeling in porphyry deposits. Sungun, NW Iran, is one of the porphyry copper deposits, in which dyke intrusions have made ore modeling more complicated than expected. Among different kinds of dykes, two types were chosen and the consequent geostatistical analyses were applied on. In this study, simple directional vario...

The article considers the geological features and ore composition of Dyusembay Central (Sayakhat) leadzinc deposit in Karsakpai metallogenic complex Kazakhstan. Historically, was considered industrially significant terms iron ores, rather than lead, zinc, copper. It is shown that composed tuffaceous, silty-sandstone, carbonaceous-terrigenous (ore-hosting), terrigenous, volcanogenic rocks assign...

Abstract The raw gold grade of a mine in Shandong is 1.42 g/t, and it accompanied by copper sulfur minerals, the embedding closely related, so difficult to obtain ideal index using original flotation process. In order realize effective recovery gold, copper, sulfur, test study mixing-separation priority carried out. results show that mineral more suitable for beneficiation process flotation. ra...
