【摘要】：常规抑制剂(如煤油)具有不溶于水,分散效果不好,用量过大的问题。为解决(极)低品位碳质金矿堆浸浸出率低这个难题,分别采用非离子型抑制剂Y-1,阴离子型抑制剂Y-2,Y-3和Y-4以及阳离子型抑制剂Y-5为新型"碳劫金"抑制剂开展试验。通过初步探索试验证明非离子型抑制剂和阴离子型抑制剂对活性炭吸金有一定抑制作用;通过浓度试验证明非离子型抑制剂Y-1和阴离子型抑制剂Y-2的加入均使金的损失率小于15%,但Y-1的用量大大减少,应为理想抑制剂;通过氰化浸出试验,证明抑制剂Y-1可溶于水,分散效果好,在加入浓度减少的条件下,相对于煤油仍可达到较好的"碳劫金"抑制效果,该新型抑制剂应可应用于低品位碳质金矿。
[Abstract]:Conventional inhibitors, such as kerosene, are insoluble in water, and the effect of dispersing is not good and the amount is too large. In order to solve the problem of low leaching rate of low grade carbonaceous gold ore, we used non-ionic inhibitor Y-1, anionic inhibitor Y-2, Y-3 and Y-4 as well as cationic inhibitor Y-5 as new inhibitors for carbon capture. Through preliminary exploration test proved that the nonionic anionic inhibitor and inhibitor Kim has inhibitory effect on activated carbon; through the concentration of the results showed that adding nonionic anionic inhibitor Y-1 and inhibitor Y-2 were the gold loss rate of less than 15%, but the amount of Y-1 is greatly reduced, should be the ideal inhibitor; by cyanide leaching and that inhibitor Y-1 is soluble in water, good dispersing effect, in reducing the concentration conditions, compared with kerosene can still reach good "carbon gold robbery suppression effect," the new inhibitors should apply to low grade carbonaceous gold ore.

【正文快照】： 碳质金矿属于常规氰化法难处理金矿。该类矿石中所含碳质物(如无定形碳、石墨和高碳氢比有机物等)对溶解金-金氰络合物具有吸附作用,一般认为,原生矿石中含有机碳化合物在0.2%以上时,将严重干扰金的氰化提取过程[1]。为解决碳质金矿氰化浸出率低这个难题,早期多采用化学氧化[2
