含钨锑多金属矿中泡沫塑料法测定金—泡塑法分离富集金的选择性及重现性

Determination of gold in complex ores containing antimong and tungsten by foam plastic method-the selectivity and repeatability of gold separation and concentration by this method

本文在研究对比了无负载泡塑和各种负载泡塑的选择性之后,选用无负载泡塑和TOB+TBP泡塑两次分离富集,在掩蔽剂和其它条件配合下使Bb、W、Mo的允许量分别达到1000、100、1000(mg)。同时研究了各种影响金回收率和重现性的若干因素。

through study and comparison of the selectivity of various loaded and unloaded foam plastic,the unloaded and TOA+TBP foam plastic are chosen for double separation and concentration of gold, causing the allowable amount of Sb W Mo to extend to 1000,100, l0000(Mg) respectively in the coordination of masking agent and other conditions. Factors influencing the recovery and repeatability of gold are studied too in this paper.
