Manufacture of Boron-free Magnesia with High Purity from Residual Brine

Qinghai Institute of Salt Lakes, Chinese Academy of Sciences, Xining 810008

Received Date: 19 September 2003

A novel method for removing boron with ion exchange resin from residual brines to manufacture boron-free magnesia is described. The concentration of boron in the target magnesia manufactured thereby from Qinghai salt lakes is lower than 5μg/g, and the typical D50 size of product is 10.625μm.
