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...

Abstract A Cu-rich polymetallic complex concentrate produced at the Garpenberg Mines of Boliden Mineral AB, Sweden is investigated. Roasting 700 °C in N 2 leads to extensive liquid formation. The calcine obtained after cooling down room temperature found be severely sintered, entrapping numerous melt nuggets. This work focuses on analyzing redistribution minor (Ag) and trace elements consequent...

Temperature variations could potentially impact flotation performance, leading to operational and economic issues. Several historical currently operating plants across Canada have reported seasonal metal losses as one of their major challenges. Improvements in efficiency at cold temperatures are important for the sustainable development industry, especially view expanding mining operations nort...

In this paper are presented general geological data for the polymetallic Hajvalia deposit. particular, we have scientific results regarding chemical and mineralogical composition of sulfur mineralizations from The distribution main metals used during mining activity in deposit has been studied with special emphasis. From microscopic description mineral samples deposit, following compositions re...
