Coal preparation system

Abstract

A coal preparation plant (50) separates a low specific gravity clean coal fraction from a high specific gravity refuse fraction, and separately processes those fractions. Run of mine coal having particles sizes up to about 4 inches is mixed with a slurry of water and magnetizable particles (53), and is introduced into a heavy media cyclone (60) to separate the high and low specific gravity fractions. The high specific gravity refuse fraction is delivered to a first magnetic separator (65) to extract the magnetizable particles, while the low specific gravity clean coal fraction is delivered to a second magnetic separator (75) to remove the magnetizable particles. The system is highly efficient and has a high processing capacity.
