应用范围说明

  主要用于微细侵染型（如黄色、红色泥质混合岩）的氧化金矿石上。它的特殊化学原理：在金的氰化过程是现在金原子表面形成溴氢基阳离子活化膜，增大氰根（CN）和氧（O₂）的分子数，提高了溶金电离速度。降低了矿物中贱金属铜、锌、锰、锑、砷、汞对已溶解的金氰络离子AU（CN）的干扰过程。促使贵液中不稳定的金氰络离子AU（CN）继续被溴氰基催化转换为有利于活性碳吸附和锌丝置换的稳定的碱土金属-金氰络合物离子团Mn+1[AU(CN₂)]。从而使金和银的总回收率提高85～95%以上。本品实际应用方法：（1）用活性碳吸附金时，PH值≥7.5～11时，温度12℃～25℃范围，吨用量50ml～100ml。（2）用锌丝置换时，温度17.5ml～40℃范围，PH值≥8.5～12.5时，吨用量75ml～150ml，以上方法。

Bromide(%)≥96  cyanide(%)≤0.10 aluminum-salt(%)≥0.2

The rate of cyanide dissolve gold(according to 1.0% bromo- hydrogen group) ≥167.3-272.1mg/cm².h

Range of usage:

This product is mainly use to minute-immersion type(such as yellow, red pelitic migmatite) gold oxide ore.it’s special chemical principle: it will form a bromo- hydrogen group cation activator membrane on the surface gold atom during cyanide process, added more molecular number of CN and Ο₂ , accelerate gold electrodissolution, reduce the disturbance of copper, zinc, manganese, antimony, arsenic and mercury in ore, urge the unstable Gold cyanide complex ion AU (CN) in ore catalyzed by bromo- hydrogen group and convert into stable earth metal-Gold cyanide complex compound ion M ⁿ﹢【AU(CN)₂】﹣，which avail absorbent absorb and zinc wire replace. And thus make tho total recovery rate of gold and sliver up to 85-95%. Actual usage: (1) While absorbent absorb gold or, PH value ≥7.5-11, temperature range:12℃-25℃, dosage:50ml-100ml/T. (2) While replaced by zinc wire, temperature range:17.5℃-40℃, PH value≥8.5-12.5, dosage:75ml-150ml/T.  The above methods just for reference.
