How to get higher recoveries via improved flotation
The potential exists for a significant improvement in the effectiveness of existing coal flotation operations. But a thorough investigation of an individual coal feed should be an important first step. Reagent dosages, cell aeration, and pulp level are important factors for existing circuit performance optimization. Pilot scale investigations of a given coal feed have shown superior flotation metallurgy for different flotation circuitry variations such as a rougher-scavenger-cleaner circuit, over the more conventional rougher only coal system. The industrial data given in this paper shows that most of the coal flotation circuits sampled are not beneficiating with respect to sulfur. The author believes, however, that it is possible to reject pyritic sulfur more effectively utilizing complex circuitry techniques. The pyritic sulfur rejection shown for the Plant I cleaner and recleaner systems and the pilot scale rougher-scavenger-cleaner circuit, along with findings by others, support this contention.
