Abstract:
An environmentally safe composition of matter for use as a promoter chemical in flotation separation of carbonates from industrial sand is disclosed. The promoter chemical replaces the standard petroleum sulfonate, glycol ether and nonphenol used in promoter chemicals with biodegradable substitutes permitting the waste from flotation separation to be disposed without fear of contamination of ground water. The biodegradable promoter is technically sound and causes little change to the flotation process.
