the cu, pb, zn, ag-au deposit of amensif is located on the northern flank of the western high atlas. this deposit is hosted in lower cambrian carbonate bars and is structurally controlled by ne-sw to e-w trending fault structures and is spatially associated with the permian 273 ma azegour granite. ore reserves are around 0.5 mt and grades are 3.21% zn, 0.58% pb, 0.86% cu with 83.31 ppm ag and 0...

The main activity of the Talvivaara Mining Company Plc. is development and exploitation ofthe deposits in Sotkamo, Finland using bioheapleaching. comprise one largest known sulphide nickel resources Europe with 1004 million tonnes ore, sufficient to support anticipated production for a minimum 45 years. mine started late 2008 will have an annual output approximately 50,000 tons when it reaches ...

This article investigates the effect of material size on efficiency flotation concentration gold-copperarsenic ores Taror deposit (Republic Tajikistan) and studies dependence gold recovery duration process with purpose developing an alternative technological scheme for processing this ore type. According to X-ray phase analysis, samples consist rock-forming minerals by 92%. Ore mineralization i...

The Kevitsa Cu–Ni sequential flotation process is characterised by poor nickel recovery during summer periods (May–September). Evidently, the water matrix in different from that other seasons; however, Cu performance scarcely affected changes across seasons. Increasingly quality was generated through a grinding-and-dissolution protocol and its impact on electrochemical reactivity of sulphide or...

Bor and Cukaru Peki are world-class porphyry deposits spatially genetically associated with the Cretaceous Timok magmatic complex. This research was conducted to determine age geochemical affinity of rocks that formed these ore deposits. Our new analyses from imply they comprise adakite-like compositions have undergone amphibole fractionation sulphide saturation processes. The zircon ages indic...
