Polymers in Mineral Processing: Proceedings of the Third UBC-McGill Bi-annual International Symposium on Fundamentals of Mineral Processing

Front Cover
Canadian Institute of Mining, Metallurgy and Petroleum, 1999 - Science - 626 pages
This proceeding is a collection of papers from eleven countries presented at the 3rd UBC-McGill International Symposium on Fundamentals of Mineral Processing. Both high molecular weight polymers (flocculants) and low molecular weight polymers (dispersants) are used in mineral processing. The topics include: experimental methods in studying flocculants and flocculation; polymeric depressants; use of dispersants and flocculants in flotation (sulfide ores, potash ores, coal preparation, etc.), effect of dispersants on pulp rheology; use of flocculants in solid/liquid separation.
