辽宁青城子地区金,银矿床地质特征及其成因郝通顺1,王可勇2,朴星海3,万多3,杨言辰1,边红业4(1.内蒙古自治区巴彦淖尔市内蒙古第二地质矿产勘查开发院2.吉林大学 地球科学学院3.吉林大学地球科学学院4.中国人民武装警察部队黄金第一总队)摘 要:对辽宁青城子地区近年来发现的高家堡子银矿床及小佟家堡子金矿床地质特征及矿床成因进行了对比研究,结果表明两类矿床是在早期沉积-变质基础上,经历了后期热液叠加改造作用的结果,其中印支期岩浆热液活动导致了小佟家堡子等金矿床形成,而其后的大气降水活动是导致高家堡子银矿床富集成......
J. Cent. South Univ. (2012) 19: 2307-2315 DOI: 10.1007/s11771-012-1276-y Separation of sulfide lead-zinc-silver ore under low alkalinity condition SUN Wei(孙伟), SU Jian-fang(苏建芳), ZHANG Gang(张刚), HU...: A complex lead-zinc-silver sulfide ore containing 2.98% Pb, 6.49% Zn and 116.32×10-4 % Ag (mass fraction) from Yunnan Province, China, was subjected to this work. Research on mineral processing......
of cyanide leaching for gold occurring in an oxides ore and a sulfides concentrate, were studied on the basis of electrochemical investigation. The results indicate that these heavy metals greatly intensify... at the same time, the heavy metals will improve the dissolution rate of gold markedly. During leaching of gold from an oxides ore, only adding heavy metals, gold leaching rate increases apparently, when......
Received 21 November 2014; accepted 11 February 2015 Abstract: Active and passive behaviors of pure gold (Au) and roasted gold ore (RGO) electrodes were investigated at 25 °C in de-aerated agitated... of passive oxides. Key words: pure gold; roasted gold ore; cyanide; passivation; electrochemical noise 1 Introduction Due to rapid depletion of free-milling gold ores, refractory gold ore processing has......
