SILVER MINERALS AND PARAGENESIS IN THE KANGJIAWAN Pb–Zn–Ag–Au DEPOSIT OF THE SHUIKOUSHAN MINERAL DISTRICT, HUNAN PROVINCE, CHINA
The Kangjiawan deposit, in the Shuikoushan district, Hunan Province, China, is a representative hydrothermal Pb–Zn–Ag– Au deposit in this region. The orebodies consist mainly of pyritic Pb–Zn ores. Silver minerals are associated with Pb–Zn mineralization. Ag-bearing Pb–Zn ores in the deposit are characterized by Ag > Cu > Sb content. Silver occurs mainly as silver minerals, such as minor argent...
متن کاملLeaching of Gold and Silver from Crushed Au-Ag Wastes
Au-Ag noble metal wastes represent a wide range of waste types and forms with various ballast elements and components. The thiourea process of gold and silver extraction from ores, concentrates or secondary raw materials consists of gold and silver leaching into the thiourea solution and the consequent precipitation of these metals from the solution. Due to the non-toxic character of thiourea i...
متن کاملکانیهای سولفوسالت بیسموت و پاراژنز آن‌ها در کانسار Cu-Ag-Au غنی از اسپیکولاریت قلعه‌زری (ایران)
Qaleh-Zari specularite-rich Cu-Ag-Au deposit is located 180 Km south of Birjand, in eastern Iran. Host rocks are mainly Tertiary calc-alkaline to K-rich calc-alkaline of 40.5±2 Ma and Jurassic sandstones and shales. Three major sub-parallel steep quartz veins are identified in different rock types, in particular andesitic rocks. The Qaleh-Zari deposit is a specularite-rich hydrothermal, Cu-Ag-A...
متن کاملThe Exploration Significance of Ag/Au, Au/Cu, Cu/Mo, (Ag×Au)/(Cu×Mo) Ratios, Supra-ore and Sub-ore Halos and Fluid Inclusions in Porphyry Deposits: A Review
This paper documents the exploration significance of Ag/Au, Au/Cu, Cu/Mo and (Ag×Au)/Cu×Mo) ratios of the supra-ore and sub-ore halos versus fluid inclusion evolution for 24 Cu, 6 Cu- Mo and 10 Cu-Au porphyry deposits worldwide. The ratios are based only on the economic and mineralized hypogene alteration zones. The results indicate that (Ag×Au)/(Cu×Mo), Au/Cu and Cu/Mo ratios increase with dec...
متن کاملDETERMINATION OF THE OPTIMUM CONDITIONS FOR RECOVERY OF GOLD FROM ZARSHURAN REFRACTORY GOLD SULFIDE ORE
The orthogonal array design has been used to determine the optimum conditions for gold recovery from Zarshuran refractory gold sulfide ore (Iran) by direct cyanidation and roasting-cyanidation. The Taguchi method was used as the experimental design to determine the optimum conditions of dissolution behavior of gold with cyanidation and roasting-cyanidation from Zarshuran refractory gold ore . T...
