对镍、钴的物相分析,前人已做过不少工作,但均限于对铜-镍硫化矿石的分析,而对像“八·二○”矿区以钒钛磁铁矿为主的矿石中镍、钴物相分析尚未见报导。为了查清“八·二○”矿区矿石镍、钴的存在形式,以利于对它的综合利用,我们初步地拟定了该矿的化学物相分析法。 根据表1资料和该矿的选冶情况,我们初步将“八·二○”矿的镍、钴分为三个相:硫化物相、氧化物相和硅酸盐相。对于硫化物相的测定试验证明以H_2O_2为选择溶剂较为
The phase analysis of nickel and cobalt, many people have done a lot of work, but are limited to the analysis of copper-nickel sulfide ore, and as the “August 20” mine dominated by vanadium-titanium magnetite ore In nickel, cobalt phase analysis has not been reported. In order to find out the existence forms of ore nickel and cobalt in “8.2.20” ore district in order to facilitate its comprehensive utilization, we initially formulated the chemical phase analysis method of this ore. Based on the data in Table 1 and the metallurgical conditions of the mine, we initially classified the nickel and cobalt of the “820” mine into three phases: sulfide phase, oxide phase and silicate phase. For the determination of sulfide phase test proved that the solvent H_2O_2 more choice
