Gossan type go d-silver ores are characterized remarkably by deep oxidized gold-silver minerals, large amount slime, high siiver content (ratio of Au:A.g = 1:50), and majority of gold and silver fine/micro-sizedly disseminated in limonite. The ore samples are refractory due to extremely difficult solid-liquid separation caused by that 45% of gangues are water-adsorptive minerals expanding into big volume of sticky pulp after leaching. Leached by all-sliming cyanidation process, recovery of Au and Ag from sample A is 93.05% and 82.72% separately,and for sample B,90.55% and 73.01% The key point of testwork lies in making choice between carbon adsorption and zinc-powder cementation. Using active carbon adsorption in stages,adsorptive rate of gold and silver reaches 100% and 99% separately. Solid-liquid separation is the key to zinc-powder cementation process and can be very effective by employing anionic flocculant of 700-1000 type. Making comparison between the two choicesCboth with relatively good metallurgies), all-sliming cyanidation'-flocculated precipitation-zinc-powder cementation processes-are recommended for engineering design of commercial plant.

铁帽型金银矿石显著特点是金属矿物氧化率高,含泥量很大,含银很富,金银比为1:50左右,金银主要嵌布于褐铁矿中,并以细粒及显微细粒为主。脉石矿物含吸水性矿物约占45%。漫出后矿浆帖稠,体积膨胀,液固分离特别困难,属难处理矿石。经全泥氰化,金、银浸出率A样为93.05%,82.72%,B样为90.55%、73.10%。实验研究的核心是采用炭浆吸附还是锌粉置换的问题。炭浆吸附金、银吸附率为100%及99%。锌粉置换采用技A—700~1000型阴离子絮凝剂,效果非常显著。经对比后,推荐选用全泥氰化—絮凝沉降—锌粉置换流程。
