Abstract:
    The invention relates to a process for separating mineral of Celestine, especially relating to a finished ore process of desliming-multiple selection. The inventive method comprises: the ore is processed with rod milling, secondary desmliming, spiral classifying, floatation-roughing separation, secondary scavenger, and fifth classifying. The invention comprises following advantages: the inventive process has better mineral separation index when it is used to classify the Celestine with large content of low-grade mud, while the finished ore productivity is 37.82-42.09%, the content of SrSO4 is 75.75-80.10% and the recovery ratio is 75.17-79.59%; the fifth floatation device has large handling capacity, lower water consumption, lower cost of finishing ore, and lower medicament consumption with simple device. The invention has stable process, simple operation and wide application in the finishing-separation production of Celestine, while it can supply high grade Celestine finished ore for producing strontium carbonate.
