ABSTRACT:
The separation of coal from pyrite is enhanced by the use of an effective amount of a polymeric acid or salt thereof as a pyrite depressant in conventional flotation processes. The polymeric acid may be a carboxylic or sulfonic acid. An example of a salt of a polymeric acid useful in the process is sodium polyacrylate.
