Reuse of process water in the flotation sulfide ores has crucial importance for environmental sustainability and improved economy. However, chemistry may be a critical subject efficiency as dissolved ion concentration increases with reuse. In this study, effects reuse on Cu-Zn ore were investigated. The flowsheet consists pre-flotation section to remove naturally floatable talc particles, seque...

Effective flotation of fine particles is a problem for mineral processing. In this paper, flocculant mostly used in heavy metal ion treatment was an arsenopyrite system. The adsorption behavior and performance PEI on the xanthate were investigated through zeta potential adsorbed amount measurements, XPS size distribution detections, micro-flotation tests. Zeta results showed that 40 mg/L polyet...

In this paper, the effect of ultrasonic pre-treatment and aeration on the flotation separation of chalcopyrite from pyrite was investigated at different amounts of potassium ethyl xanthate (KEX), as a collector, and pH values. Artificially-mixed samples of chalcopyrite and pyrite were subjected to flotation studies to understand the effect of aeration with or without ultrasonic tre...
