gold sodium cyanide

基本解釋

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.
試驗(yàn)結(jié)果表明：提高礦樣的磨礦細(xì)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(jià)下跌導(dǎo)致氰化鈉需求下降，價(jià)格下挫，局部地區(qū)對(duì)中國高品級(jí)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%.
將脫藥后的精礦用氨-氰混合液浸出，在氨和氰化鈉的用量比為5 .92∶8的最佳比例下，金的浸出率可大幅度提高到90 %以上；
