粘土煅烧

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.

同时，对尾矿用于代粘土和矿化剂配不同品位石灰石的20个生料配方进行了实验室高温炉不同温度下的煅烧试验，并对煅烧后的熟料样品进行了游离CaO和X衍射分析，得出了不同尾矿用于代粘土或矿化剂的合理配方和煅烧工况，从而为大规模产业化利用提供指导性参考依据。

Through the researches, we found that raw material of high silicon low alkali gritstone composition and high alkali clay composition had been calcined under 1400℃, so f-CaO in clinker is lower than 1.0%, even lower than this number.

通过试验研究发现，高硅低碱砂岩配料和高碱粘土配料两方案的生料经1400℃煅烧后，熟料中的f-CaO均在1.0％以下，且远低于这个数。

This article studies calcining temperatures and time effect on the content of iron pyrites in rectoriteor by calcining rectoriteor in Zhongxiang Hubei province to remove the iron pyrites in them.
