一、前言广东某含铀多金属硫钼矿属铀-钼型中低温热液矿床。矿石中铀、钼、金、银均达到工业综合利用品位(U0.012—0.08％;Mo0.30％;Au1—1.2克/吨;Ag30克/吨),铀钼密切共生。钼的主要矿物是硫钼矿和蓝钼矿;蓝钼矿和主要呈离子吸附状态存在的铀在弱酸或弱碱溶液中水溶性大;金以自然金存在,粒度细小,一般为0.002—0.01毫米;银的主要矿物是溴化银,在400℃以上的
I. Preface A uranium-bearing polymetallic sulfur-molybdenum mine in Guangdong is a uranium-molybdenum medium-low temperature hydrothermal deposit. Uranium, molybdenum, gold and silver in the ore all reach the level of industrial comprehensive utilization (U0.012-0.08%; Mo0.30%; Au1-1.2g / t; Ag30g / t) and uranium-molybdenum are closely intergrowth. The main minerals of molybdenum are sulfur molybdenum ore and blue molybdenite; blue molybdenum ore and the main state of ion adsorption of uranium in weak acid or weak alkali solution is water-soluble; gold is present in natural gold, the particle size is small, usually 0.002-0.01 Mm; silver’s main mineral is silver bromide, above 400 ℃
