TL;DR: In this article, the authors highlight the effect of different pretreatment methods on the flotation of low-rank/oxidized coals and highlight the impact of different pre-treatment methods on coal flotation.
158 citations
TL;DR: In this paper, a review of coal beneficiation technologies for low-rank coal is presented, including physical (gravity and magnetic separation), chemical (leaching), physico-chemical (flotation and oil agglomeration), and bio-beneficiation technologies.
150 citations
TL;DR: In this paper, XPS and SEM were used to indicate the changes in surface properties of bituminous coal during natural weathering processes, which not only changed surface chemical composition but also changed surface topography.
143 citations
TL;DR: In this paper, microwave pretreatment is used to improve the floatability of oxidized coal in an experimental setup, and the results of flotation tests show that the combustible recovery increases with microwave pre-treatment time.

Abstract: THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.
