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

项目描述：本项目支持密歇根理工大学S.K. Kawatra博士与印度博帕尔地区研究实验室T.C. Rao博士之间的合作。这项研究的目的是了解夹带粒子的行为。在煤的泡沫浮选过程中，颗粒从矿浆阶段被输送到泡沫阶段，夹带是重要的机制之一。在这个过程中，颗粒进入浮选泡沫的底部，悬浮在气泡之间的水中，向上和向外转移。这一过程受到许多因素的影响，如颗粒大小、形状和表面化学，其影响尚不完全清楚。本研究将在间歇式浮选池和连续式浮选池中进行实验研究。实验将使用特性良好的煤和纯化组分的合成混合物进行，以弥补在煤中矿物的非均质混合物中确定颗粒特性的困难。范围：该项目涉及两位科学家的合作，他们在处理基础科学问题的测试和数学建模方面具有互补的经验。这个问题的解决可以更好地理解粒子夹带过程中涉及的因素，未来可以在各个行业中得到应用。＊＊＊

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. ***
