电化学控制接触角测定结果表明 ,三硫代碳酸盐 (TTC)更比二硫代碳酸盐 (即黄药 ,DTC)易于氧化成相应的二硫醇盐。捕收剂常规吸附量分析结果表明 ,TTC捕收剂可有效地用于硫化矿混合浮选中。过去的分批浮选试验研究证明 ,TTC捕收剂浮选硫化铜矿物和铂族金属硫化矿物很有效。最近 ,在美国所进行的分批小型试验和在南非Anglogold选矿厂所进行的工业试验中 ,评价了TTC捕收剂浮选含金黄铁矿的效果。还在铂族金属矿石小型浮选试验中应用了TTC捕收剂。在这些情况下TTC捕收剂都获得了高效的分离效果。有关TTC捕收剂对含金黄铁矿特效的结构 (官能团为-O -CS2 和 -S -CS2 )作用的基础理论研究正在美国犹他大学进行中。评价了捕收剂结构在用空气和氮气作为浮选气体时的作用。所用的方法有评价矿物疏水性的电化学控制接触角测定和解释捕收剂在矿物表面上吸附现象的红外光谱
Electrochemical controlled contact angle measurements showed that trithiocarbonate (TTC) is more easily oxidized to the corresponding dithiolate than dithiocarbonate (ie, xanthate, DTC). Conventional adsorption capacity analysis of collector shows that TTC collector can be effectively used in sulphide mixed flotation. In the past, batches of flotation tests proved that TTC collectors were effective for flotation of copper sulfide minerals and platinum group metal sulfide minerals. Recently, the effect of TTC collector flotation of gold-containing pyrite was evaluated in both batch-by-batch pilot tests conducted in the United States and industrial tests conducted at the Anglogold beneficiation plant in South Africa. TTC collectors have also been used in small flotation tests for platinum group metal ores. TTC collectors are highly efficient at these conditions. A fundamental theoretical study on the effect of TTC collectors on the structure of the gold bearing pyrite (functional groups -O-CS2 and -S-CS2) is currently underway at the University of Utah. The collector structure was evaluated for its role in using air and nitrogen as the flotation gas. The methods used include the determination of the electrochemical control of mineral hydrophobic contact angle measurement and interpretation of the collector on the mineral surface adsorption phenomenon of infrared spectroscopy
