近年来,作为铁矿石浮选的捕收剂,仍是以采用氧化石腊皂与煤油、氧化石腊皂与塔尔油的混合药剂、或粗硫酸盐皂为主。但由于该类药剂有的原料缺,有的价格高,因此寻找新的来源广,价格低廉又具有选择性好的捕收剂,一直是研究铁矿石浮选的主要课题。为此,我们曾对东乡铜矿赤铁矿系统采用以石油磺酸钠与碱渣作为赤铁矿浮选的捕收剂进行了试验,获得较好指标。一、矿石性質 (一)原矿石的光谱定性和化学分析如表1、2。
In recent years, as a collector of iron ore flotation, still using the oxidation of paraffin soap and kerosene, paraffin soap and tar oil mixture, or crude sulfate soap. However, due to lack of raw materials and high prices of some of these pharmaceuticals, it is always a major topic to study the flotation of iron ore to find new collectors with low price and good selectivity. For this reason, we have tested Donghe Copper Mine’s hematite system using petroleum sodium sulfonate and caustic soda as the collector of hematite flotation, and obtained better indicators. First, the nature of ore (A) of the ore qualitative and chemical analysis of the spectrum as shown in Table 1,2.
