一种非氰浸出剂及其用于金矿浸出的方法
摘要：
一种非氰浸出剂，包括硫氰酸盐、硫脲、硫氰和氰酸盐，各组分摩尔比分别为4～8∶0.5～1∶0.5～3∶1～2。本发明的非氰浸出剂具有浸出率高，浸出速度快，性能稳定，适应范围广，成本低廉，环境适应能力强，工艺简便的优点，本发明可将高硫高砷难处理硫化金矿中金的浸出率提高到96％以上。
摘要（英）：

Disclosed is a non-cyanide leaching agent. The non-cyanide leaching agent comprises thiocyanate, thiourea, thiocyanogen and cyanate. The molar ratio of each component is 4-8:0.5-1:0.5-3:1-2. The non-cyanide leaching agent has the advantages of being high in leaching rate, high in leaching speed, stable in performance, wide in applicable range, low in cost, high in adaptive capacity to environment and simple and convenient in technology, and the leaching rate of gold in sulfuration gold mine with high sulfur and high arsenic and difficult to process is improved to above 96%.
