• Au and Ag deportment in an intermediate sulfidation Ag-Pb-Zn system. Deportment calculation using quantitative mineralogy, bulk mineral chemistry. Deportments are highly variable between samples due to mineralogical contrast. Gold the Freiberg district is primarily hosted by arsenopyrite electrum. Silver sulfosalts fahlore. data essential for planning of mining minerals processing operations....
barika gold (and silver) rich massive sulfide deposit is located 18 km east of sardasht, north western part of sanandaj-sirjan metamorphic zone. rock units outcropped in this area are cretaceous metamorphosed volcano-sedimentary rocks in green schist facies, and include association of meta-andesite, meta-tuffite, phyllite and slate rocks, where the meta-andesitic unit (kmv1) is host rock to the...
Gold - Polymetal mineralization of Kohe-zar area is located alout 35 kilometers southwest of Torbat - Heydarieh in Khorasan province. Mineralization was oeeured in quartz - speeularite ± pyrite ± chacopyrite veins and vein lets. The main ore minerals are specularite, chalcopyrite, pyrite, avinite (Bi - bearing tetraedrite), acanthite, native bismuth (occurred intergrowth with barite), nat...
