由于硫化矿石的浮选受矿石的氧化态和不同矿物的含量、磨矿过程中磨矿介质与具有不同剩余电位的硫化矿物之间的微电池反应、矿浆中的溶解离子等影响,所以,电化学测试技术已成功地用于解释硫化矿物的浮选行为。然而,虽然来自Bushveld火成岩的Merensky矿石可以认为是一种复杂硫化矿(含有多种硫化矿物),但是硫化矿物的总量不足1%。因此,采用电化学测试技术对Merensky矿石的浮选行为进行了研究。在用不同磨矿介质和添加或不添加硫酸铜时,测量了矿物的电极电位。试验结果表明,应用电极电位对Merensky矿石的浮选行为进行解释会产生误导,这可能是由于矿石中硫化矿物含量太低,以及其它因素(如起泡剂的稳定性和硫酸铜添加及磨矿介质的影响因素)有很大的关系。
Since the flotation of sulphide ores is affected by the oxidation state of the ores and the content of different minerals, the micro-cell reaction between the grinding media and sulphide minerals with different residual potentials and the dissolved ions in the ore during the grinding process, Chemical testing techniques have been successfully used to explain the flotation behavior of sulphide minerals. However, although the Merensky ore from Bushveld igneous rock can be considered as a complex sulphide ore with many sulphide minerals, the total amount of sulphide minerals is less than 1%. Therefore, the electrochemical test technique was used to study the flotation behavior of Merensky ores. The electrode potential of the mineral was measured with different grinding media and with or without copper sulphate. The experimental results show that the interpretation of the flotation behavior of Merensky ores using electrode potentials can be misleading, possibly due to too low sulfide mineral content in the ore and other factors such as the stability of the blowing agent and the addition and grinding of copper sulphate Media factors) have a great relationship.
