Abstract:This paper introduces the situation of a large-scale state-owned enterprise's sulfur separation system before transformation, the problems after transformation, and the final solution. Through the practical activities of technical transformation and the selection of the technological process of separation and flotation of coarse and fine particles, it is clarified that the technical transformation needs to be optimized continuously through practice, and the technical transformation can not only be limited to the existing data to solve the problems faced, but also to deal with a series of problems that may be brought about by the change of ore properties, which has certain effect on improving the utilization rate of mine resources guiding significance.
