Technical Plan for the New Zhudongkuang Magnetite Concentrator of Bayan Obo Iron Mine, BaoSteel

Abstract

Abstract: To reduce the production cost, improve the economic benefit and reduce the pollution to the environment of Baotou urban area, BaoSteel decided to build a new Zhudongkuang magnetite concentrator of Bayan Obo Mine that is capable of treating annually 8 million t run-of-mine ore and producing 3 million t iron concentrate.The technical process plan for this new concentrator is described, including its crushing process, staged grinding-staged low intensity magnetic separation (LIMS) process and reverse flotation for the LIMS concentrate.

Key words: Zhudongkuang Concentrator, Magnetite ore, High-pressure roller mill, Staged grinding, Reverse flotation
