Separation of silver from silver-manganese ore with cellulose as reductant ZHANG Xiao-yun(张小云), TIAN Xue-da(田学达), ZHANG Dong-fang(张东方) College of Chemical Engineering, Xiangtan University... silver-manganese ore with a grade of 3.15×10-4 was concentrated by a combined beneficiation technique including magnetic separation, flotation, reducing leaching and gravity desliming. The major silver......
was only about half that of gold. Since silver may occur as silver sulfide minerals in the ore, e.g. acanthite (Ag2S) and argentojarosites (AgFe3[SO4]2(OH)6), the low solubility of these silver sulfides... on the leaching of actual gold-silver ore. 2 Experimental 2.1 Samples and reagents A pure gold rod (purity of 99.95 %) with a diameter of 2.4 cm was used in the gold leaching tests. A synthetic silver sulfide......

Mineralogical Characterization of a Polymetallic Sulfide Ore to Improve Silver Recovery陈代雄1,2,XIAO Jun1,21. School of Minerals Processing and Bioengineering, Central South University2. Hunan... on the mineralogical characterization for the polymetallic sulfide ore, the way to improve silver recovery was studied. The results showed that silver was the most valuable metal whose grade......
Characterization of refractory behaviour of complex gold/silver ore by diagnostic leaching O. CELEP1, ?. ALP1, H. DEVEC?1, M. VICIL2 1. Mining Engineering Department, Karadeniz... of a refractory ore to the extraction of gold and silver by cyanide leaching was investigated. Diagnostic leaching tests were also performed to shed light on the refractory characteristics of ore. The leaching......
