3,000,000t/y Aggregate Project of Limonite in Yunnan Province
With the joint efforts of the different departments, we finally put up with a plan. In 2006, the plant built an iron separation production line with an annual capacity of 500,000 tons. The tailings are made up of magnetite and limonite. Due to the high magnetism of magnetite, SLon Wet Drum Magnetic Separator removes magnetite from the metal mix.
