gold sodium cyanide

基本解释

The results showed that gold recoveries could be increased by fine grinding of concentrates , raising concentration of sodium cyanide in leaching solution and adding the regent SDM.
试验结果表明：提高矿样的磨矿细度和浸出液中氰化钠的浓度以及加入SDM助浸剂，均可提高金的氰化浸出率。
The drop of global gold price results in the decrease of demand and the fall of price for sodium cyanide. However, the Chinese high grade flake product is still in demand at some regions.
国际金价下跌导致氰化钠需求下降，价格下挫，局部地区对中国高品级片状有一定的需求。
When the dereagented concentrate was leached with ammonia-cyanide mixed solution at the best ammonia-to-sodium cyanide ratio of 5.92∶8, the gold leaching rate could be greatly increased to over 90%.
将脱药后的精矿用氨-氰混合液浸出，在氨和氰化钠的用量比为5 .92∶8的最佳比例下，金的浸出率可大幅度提高到90 %以上；
