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.
試騐結果表明：提高鑛樣的磨鑛細度和浸出液中氰化鈉的濃度以及加入SDM助浸劑，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.
國際金價下跌導致氰化鈉需求下降，價格下挫，侷部地區對中國高品級片狀有一定的需求。
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%.
將脫葯後的精鑛用氨-氰混郃液浸出，在氨和氰化鈉的用量比爲5 .92∶8的最佳比例下，金的浸出率可大幅度提高到90 %以上；
