Review of important developments since the 1st IMPC in …

Numerous studies have been undertaken on contact angles since the 1st IMPC. Many of these related to the relationship between spreading coefficient and the interfacial tensions (e.g. Kitchener, 1960, Leja and Poling,1960).Other studies focused on the relationship between contact angle and recovery (Smith and Lai, 1966) and the …

Flotation as a Separation Process

Without this process, many familiar metals and inorganic raw materials would be exceedingly scarce and costly because the high-grade ores that could be processed by simple physical and mechanical methods have long since been used up (1). Flotation initially originated from the field of mineral processing, usually termed froth …
