摘要

disclosed is a process for separating resin from a mixture of resin-bearing coal particles by increasing the pH of a froth flotation process to a value of at least 12. Particles of reduced size resin-bearing coal are preferably mixed with water to from a slurry. The pH of the slurry is then adjusted with a chemical agent to about 12. The slurry is then subjected to froth flotation. The coal particles aggregate to one another allowing the remaining resin-rich particles to attach to the bubbles formed during the flotation process. A much improved separation efficiency for resin flotation from coal is observed.
