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.

A composition of matter, for use as a promoter in flotation separation of carbonates from minerals comprising a mixture of Tall Oil/Fatty Acid and Linseed Oil.
A composition of matter, for use as a promoter in flotation separation of carbonates from minerals, comprising a mixture of Tall Oil/Fatty Acid and Linseed Oil wherein the ranges of said individual constituents of the composition are Tall Oil/Fatty Acid between 50 and 95 percent, and Linseed Oil between 50 and 5 percent.
A composition of matter, for use as a promoter in flotation separation of carbonates from minerals, comprising a mixture of Tall Oil/Fatty Acid and Linseed Oil wherein the ranges of said individual constituents of the composition are 50-95 percent Tall Oil/Fatty Acid and 50-5 percent Linseed Oil and wherein the rosin content of said Tall Oil/Fatty Acid ranges between 0 and 15 percent.
A composition of matter, for use as a promoter in flotation separation of carbonates from sand, comprising a mixture of Tall Oil/Fatty Acid and Linseed Oil wherein the ranges of said individual constituents of the composition are 85-90 percent Tall Oil/Fatty Acid and 5-10 percent Linseed Oil and wherein the rosin content of said Tall Oil/Fatty Acid ranges between 0 and 5 percent.
A composition of matter, for use as a promoter in flotation separation of carbonates from sand, comprising a mixture of Tall Oil/Fatty Acid and Linseed Oil wherein the ranges of said individual constituents of the composition are 85-90 percent Tall Oil/Fatty Acid and 5-10 percent Linseed Oil and wherein the rosin content of said Tall Oil/Fatty Acid ranges between 2 and 15 percent.
