我国南方某金矿，自1955年以来已堆存尾矿35万t以上，其中金、锑、钨的平均品位分别为4.2g/t、0.8%、0.18%，金属储量分别为1.473t、2517t、569t。根据老尾矿的性质、长春黄金研究院经过一系列的试验研究表明，应采用浮选回收老尾矿中的锑和一部分金，对浮选尾矿进行氰化浸出再回收金。由于老尾矿中的锑大部分已氧化，浮选回收时，回收率并不高，剩余的锑对氰化浸出仍有影响。

At a gold mine in southern China, since 1955 has stockpiled tailings of more than 35 million T, which the average grade of gold, antimony, tungsten respectively 4.2g/t, 0.8%, 0.18%, metal reserves were 1.473t, 2517t, 569t. According to the nature of the old tailings, Changchun Gold Research Institute after a series of experimental studies show that the flotation recovery of antimony and gold in the old tailings, the flotation tailings of cyanide leaching of gold. As most of the antimony in the old tailings has been oxidized, the recovery rate is not high, and the remaining antimony is still affected by cyanide leaching.
