本文概括了在开发处理量大的精选新方法方面的新技术成果,并对分选方法的经济效果作了概述。以此法,矿粒在磁流体重介质分选过程中所受的固有重力限制,因矿浆在稀的低粘度水基磁流体中的转动而得到克服。分选结果与通过旋转重介质所得的分选结果相似,只是通过磁力作用调节流体的有效比重,以实现在1.5～21.0比重分离点条件下的分选过程。精确度取决于分离点,对石英和其它轻矿物,误差小于0.1。

This paper summarizes the new technological achievements in the development of a large selection of new methods and gives an overview of the economic effects of the sorting method. In this way, the inherent gravitational constraints imposed by mineral particles in the process of magnetic fluid medium separation are overcome by the rotation of the slurry in a dilute low-viscosity water-based magnetic fluid. The sorting result is similar to the sorting result obtained by rotating the heavy medium except that the effective specific gravity of the fluid is adjusted by the magnetic force so as to achieve the sorting process under the condition of the specific gravity of 1.5 to 21.0. The accuracy depends on the separation point, for quartz and other light minerals, the error is less than 0.1.
