摘要
文中着重研究了浸前中温焙烧对贫细微含金褐铁矿石硫脲法浸金的影响。研究结果表明：中温焙烧不但可提高硫脲浸金速度和金的浸出率，而且可使硫脲的单耗降低５～６倍，使每吨矿石的硫脲用量降至８００ｇ／ｔ矿石；同时，对其机理进行了详细的研究和探讨。
The influence of medium temperature roast of tinylimonite ore containing small amount gold on extraction of gold by using thiocarbamide as extractant is studied in this paper.Results show that medium temperature roast of tinylimonite ore not only can improve gold leaching rate but can make the unit consumption of thiocarbamide reduce by 5～6 times i.e.800g/t reduced.The mechanism is also studied in detail in the paper.
