Composite iron ore beneficiation. Most of the iron ores in China contain more than two kinds of iron minerals, and the more kinds the worse the selectivity. This type of iron ore to co-exist with hematite, mirror iron ore, needle iron ore, rhodochrosite, limonite and other weak magnetic iron minerals are more difficult to select.

Beneficiation of iron ore. United States Patent 4301973. Abstract: 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.
