矿泥对氰化浸出影响的试验研究

Experimental study on influence of mud mineral on cyanide leaching

矿泥中的粘土矿物易絮凝成网状多孔结构物，能够吸附已溶金，影响金的氰化浸出。为控制矿泥影响，含泥物料可在高碱、高氰条件下进行两浸两洗；从物料中将矿泥分出，进行炭浸，可显著提高金浸出率。

The mud in mineral is liable to be floculated to porous or network constituent which adsorb dissolved gold,influencing gold leaching rate.For controlling the influence of mud mineral,the material containing mud can be leached and eluted twice in the condition of high intensity alkali and high density cyanide in order to separate the mud from mineral and carry out carbon in leach.By this way,the leaching rate can be raised markedly.
