Book Description
Hardbound. Column flotation is one of the most important new developments to emerge in mineral processing technology in the last 50 years. Currently there is much research and development interest worldwide, and Professors Finch and Dobby are among the leading practitioners in the field. Column Flotation covers both fundamental and applied aspects. Following an examination of the properties of the collection and froth zones, there is detailed treatment of cleaning and selectivity, focussing on their dependence on operating variables. It concludes with an examination of the practical questions of column simulation, scale-up and control. The book is profusely illustrated throughout, with comprehensive glossary and nomenclature sections to assist newcomers to the field. Invaluable reading for mineral processing and chemical engineers, both practising and students, it provides a solid foundation to this rapidly emerging technique.

Book Description
A practical examination of separation ore from rocks on an industrial scale. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.

Book Description
A project to evaluate the performance of the Virginia Tech Microbubble Column Flotation (MCF) process in an operating coal preparation plant was continued during this past quarter. The project is concerned with the collection of process operating data using a 30-inch diameter column, and using these data to scale-up to a prototype, full-scale plant column. The work is being carried out at the Marrowbone Preparation Plant owned by the Shell Mining Corporation. Work during the past reported period primarily concentrated on the completion of a parametric study to evaluate the performance of the 30-inch diameter column. The preliminary results obtained from the parametric study suggest that higher gas flow rates and frother additions appear to have a beneficial effect on separation efficiency. However, under these conditions, a larger wash water flow rate was necessary to offset the increased flow of feed water to the product stream. The parametric testing results indicated that the height of the stabilized froth zone had only a limited impact on the separation efficiency, except under conditions of high feed rates. A more detailed analysis of the response surface data is currently under way. Work in other areas (Task 2.5 - Control systems and Task 3.3 - Column Testing) is continuing, but has progressed at a slower pace than originally anticipated. The appendix contains data on energy recovery, product ash content, sulfur rejection, and separation efficiency. 32 figs., 5 tabs.

Book Description
Solid phase residence time distribution data for both the froth and pulp phases is reported for a laboratory column flotation cell. From this data residence time distribution models for the pulp and froth phases have been developed. A plug flow reactor with recycle was found best to describe the behaviour of the solids in the froth phase and a tanks-in-series model was most suitable for the solids in the pulp. The feed region was found to be highly turbulent and was modelled using a mixed reactor with dead volume. These models are compared to those proposed by other researchers and the problems associated with using the dispersion model highlighted. The froth model parameters were shown to be related to the processes occurring in the column. A sensitivity analysis revealed that the model parameters were largely independent.
