采用浮选+全泥氰化工艺对云南省某银矿石进行提银选矿试验研究。矿石中银多金属复硫盐经浮选富集得到银精粉;浮选尾矿再全泥氰化提银。浮选作业所得银精粉品位5761.54 g/t,回收率21.91%;浮选尾矿全泥氰化浸渣品位19.28 g/t,浸出率78.85%。综合回收率84.12%。银多金属复硫盐是影响浸出率的关键因素,预先将其有效浮选,有利于提高银氰化浸出率。
採用浮選+全泥氰化工藝對雲南省某銀礦石進行提銀選礦試驗研究。礦石中銀多金屬複硫鹽經浮選富集得到銀精粉;浮選尾礦再全泥氰化提銀。浮選作業所得銀精粉品位5761.54 g/t,迴收率21.91%;浮選尾礦全泥氰化浸渣品位19.28 g/t,浸齣率78.85%。綜閤迴收率84.12%。銀多金屬複硫鹽是影響浸齣率的關鍵因素,預先將其有效浮選,有利于提高銀氰化浸齣率。

Some experimental studies have been done on the technical flow and all slime cyanidation for separation of silver ore in Yunnan province. The silver concentrate resulting from silver polymetallic sulfate by flotation contained an amount of silver at 5761.54 g/t with a recovery of 21.91%. The flotation tailings were leached out by all slime cyanidation to produce a concentrate containing 19.28 g/t Ag with a recovery of 78.85%. The total recovery rate was 84.12%. Silver sulfate was the one of key factors affecting the leach of silver in all slime cyanidation process. The flotation to extract firstly silver sulfate facilitated leaching of silver in the following cyanidation process.
