Entrainment in Froth Flotation of Fine Coal, Indo-U.S. Collaborative Research

小行星9415418 描述：本项目支持S.K.博士与密歇根理工大学的Kawatra和T.C. 印度博帕尔地区研究实验室的拉奥说。 该研究旨在了解夹带颗粒的行为。 夹带是泡沫浮选法处理煤的重要机理之一，其中颗粒从矿浆相输送到泡沫相。 在该过程中，颗粒进入浮选泡沫的底部，并悬浮在气泡之间的水中向上转移并离开浮选槽。 该过程受到许多因素的影响，例如颗粒大小，形状和表面化学，其影响尚未完全了解。 本研究将在间歇式和连续式浮选槽中进行实验研究。 实验将进行使用良好的特性煤和合成的混合物的纯化成分，以弥补在煤中的矿物的非均质混合物中确定颗粒特性的困难。 适用范围：该项目涉及两名科学家的合作，他们在测试和处理基本科学问题的数学建模方面具有互补的经验。 这个问题的解决方案，导致更好地了解颗粒夹带过程中所涉及的因素，可能在未来的各个行业中有应用。 ***

9415418 Kawatra Description: This project supports collaboration between Dr. S.K. Kawatra of the Michigan Technological University and Dr. T.C. Rao of the Regional Research Laboratory in Bhopal, India. The research aims at understanding the behavior of entrained particles. Entrainment is one of the important mechanisms in processing of coal by froth flotation where particles are transported from the pulp phase to the froth phase. In that process particles enter the base of a flotation froth and are transferred up and out of the flotation cell suspended in water between the bubbles. The process is subject to the influence of many factors, such as the particle size, shape and surface chemistry, whose effects are not fully understood. In this research, experiments will be carried out to conduct studies in batch and continuous flotation cells. Experiments will be conducted using both well-characterized coals and synthetic mixtures of purified components, to compensate for the difficulty of determining particle characteristics in the heterogeneous mixture of minerals in coal. Scope : This project involves collaboration by two scientists with complementary experiences in testing and in mathematical modeling in dealing with a fundamental science problem. The solution of this problem, leading to better understanding of the factors involved in the process of particle entrainment, could have applications in the future in various industries. ***
