| 摘 要： | 通过对黔西南贞丰某一典型的高粘土质低晶位金氧化矿石浸出、粘结剂配比实验和催熟剂Ｎｏ．１浸金实验研究，表明少量复合粘结剂的加入，极大改善矿石的性质，提高浸取液的溶液渗稼性。４％复合粘结剂的掺入量，不仅使成球粒在２４ｈ内的抗坟强度达到４．０ｋｇｆ／ｃｍ＾２，而且在２４ｈ内氰化反应近乎完全，金溶出率高达９６％。

| Abstract: | By determining the gold leached directly from a typical clay high oxidized ore in Zhengfeng County (Guizhou Province), and estimating the effects of adhesive and No.1 on gold leaching, the experimental results showed that even if a small amount of adhesive was added, the properties of oxidized ore were improved greatly, and the permeability of solution was also raised strongly. After addition of 4wt% complex adhesive, the compression strength of grained sample reached 4.0 kgf/cm 2 in 24 h, the reaction between gold and NaCN solution in the oxidized ores was nearly accomplished, and the leachability of gold was up to 96%. |
