Study on the Interaction between Galena and Sphalerite

In PbZn ore flotation, unintentional activation of sphalerite often leads to difficult separation of Pb and Zn minerals, during which grinding plays a key role in unintentional activation. Therefore, the aim of this study was to evaluate theponent changes of two different mineral particles and to propose the interaction between galena and sphalerite during mixed grinding using
