尾矿

On the basis of characteristic analysis on all kinds of mineral tailings of copper lead zinc, mineral tailings was classifying according to its application. At the same time, the calcining experiment for twenty material prescriptions of the mineral tailings substituting the clunch or mineralizer mixed with different grades of limestone was actualized in the laboratory's heating kiln under the different temperature. After the fCaO analysis and the X-diffraction test to the calcined samples, the reasonable prescriptions and optimal calcining condition were put forward for different kinds of mineral tailings used to substitute the clunch or mineralizer, the research conclusion offers the instructional reference for the large-scale industrialization production.
