US4301973A Beneficiation of iron ore Google Patents

Isostearic acid, a liquid isomer of stearic acid, is used as an agent in a froth flotation process to concentrate the iron oxide in iron ores. By use of this flotation agent, the iron oxide in the ground ore is directly floated away from the remainder of the ore. The process enables a high amount of iron oxide to be concentrated from low grade ores.
