Application of Magnetic Forces to Enhance Solid-liquid Separation in the Metals Industry

Abstract

The use of magnetic seed materials and flocculants to extend the application of magnetic, vacuum filtration to nonmagnetic pulps is examined. The addition of a flocculant can enhance the capacity of drum and disk magnetic filters when treating partially-magnetic materials. The use of seed magnetite with a flocculant also improves the dewatering of fine hematite pulps in a drum magnetic filter. However, the use of a flocculant and seed magnetite has only limited success in improving filtration in a disk magnetic filter with a fine quartz pulp. A disadvantage of magnetic vacuum filtration with seeding appears to be an increase in cake moisture due to water entrapment in the flocs resulting from agglomeration and magnetic attraction.
