“抢先吸附”是指矿石、粘土矿物和其它种类矿物中的碳质组分从氰化物溶液中吸附金氰配合阴离子的作用。当所处理的矿石为“抢先吸附”型时 ,通常用炭浸法代替炭浆法提取金。Ｋ .Ｌ .Ｒｅｅｓ等人研究了活性炭对从一种氧化矿和三种硫化矿 (浮选原矿、铜精矿和黄铁矿精矿 )中浸 “Pre-adsorption” refers to the role of carbonaceous components in ores, clay minerals and other kinds of minerals that adsorb the complex of cyanide and cyanide from the cyanide solution. When the ore is treated as “pre-adsorption” type, the carbon-leaching method is usually used instead of the carbon slurry to extract gold. K. L. Rees et al. Studied the effect of activated carbon on immersion from an oxide ore and three sulphide ores (flotation ore, copper concentrate and pyrite concentrate)
