摘　　要：针对山东某风化壳型金矿进行了氰化浸出试验研究,考察了磨矿细度、氰化钠用量、石灰用量、液固比、搅拌时间等对金浸出效果的影响规律。试验结果表明,较粗的磨矿细度和较低的矿浆浓度对浸出更有利,在最佳的试验条件下,该矿石的金浸出率可达到95.87%,炭吸附率可达到99.58%。Cyanide leaching tests on a weathered gold ore in Shandong have been conducted, during which grinding fineness, cyanide dosage, lime dosage, liquid-solid ratio and mixing time are investigated. The test result shows a coarse grinding fineness and a low solid concentration are better. With the best condition, 95.87 percent of gold can be recovered, and the carbon adsorption rate can reach 99.58%.
