摘要
硫化矿物在一定条件下容易被氧化，其氧化过程、机理及其对矿物浮选分离的影响，是硫化矿物浮选领域的一个重要研究课题。论文分别以晶格能、氧耗量和交换电流密度值的大小确定了三种硫化矿物的氧化反应速度顺序，并考查了ｐＨ值和温度对硫化矿物氧化反应的影响。从而为这三种矿物在有氧条件下的浮选行为的解释提供了重要依据。
Sulphide minerals are readily oxidized under certain conditions. The course and mechanism ofthe oxidization,and their influence on the separation of minerals by flotation have been a major study subject in the field of the sulphide mineral flotation,In this study,a sequence of oxidization rate for three sulphide minerals has been established according to the deta of lattice energy, oxygen consumption and exchanging current density.The effect of pH value and temperature on the oxidization reaction has also beenobserved ,thus providing an important basis for the explanation of the flotation behaviour of the mineralsunder the conditions where oxygen is present.
