Preparation of magnesium hydroxide from leachate

2014-2-1  1. Introduction. Magnesium in the form of dolomite constitutes a main impurity in sedimentary phosphate ores. Due to depletion of high-grade phosphate ore, the unexploited reserves of phosphate rock tend to contain less phosphate and more dolomitic carbonate (Zheng et al., 2001).The low-grade ores need beneficiation to be fit for subsequent processing.
