Magnetic Separation and Flotation Technique for the Production of High Quality Trona Concentrate

The technology utilizes a combination of magnetic separation and flotation techniques to produce trona concentrate with high grade of 98% trona and recovery of 83.6%. The magnetic and non-magnetic products are separated using a high intensity magnetic roll. This is followed by flotation of the non-magnetic product using a conventional flotation cell. Our technology would substantially improve the flowsheet of trona beneficiation by replacing all chemical treatment of trona with physical separation process.

This technology will provide a new product, a high quality trona which may be acceptable as a substitute for soda ash in certain markets. Soda ash is the primary constituent required by the glass industry (49%), chemical plants (28%), soaps and detergents (11%), distributors (4%), flue gas desulfurization (2%), paper and pulp (2%) and water treatment (1%).

Stage of Development
A provisional patent application with the U.S. Patent and Trademark Office is being drafted. The technology is available for developmental research support/licensing under either exclusive or non-exclusive terms.
