In cement production, we know the mineral composition of clinker in the heat of hydration of cement is an important factor in the different clinker minerals have different hydration time and hydration exothermic heat release. Yu Heng mining through cement test, decided to use lead-zinc mine tailings as raw material to the hot Portland cement clinker burning. (1) The incorporation of lead and zinc tailings, raw material in the process of firing clay than the early appearance of the liquid ingredients 1l , raw material easy to burn better. At 1400 for 30min, the free calcium oxide content has been less than 1% of clinker has been firing. (2) According to the results of scanning electron microscopy analysis, fossil morphology is good. (3) The firing of the clinker mixed with gypsum in the preparation of the hot cement, 3d and 7d of the release of heat energy are in line with national standards of cement 425. (4) clinker content of heavy metals leaching solution is lower than national standards for hazardous waste, no harmful effects on water quality. (5) The lead-zinc mine tailings in the mineralization of impurity ions, to take the high iron and low alumi921201193005, high-saturated solution than the ingredients, the ingredients can be fired with lead-zinc mine tailings in line with national standards in the heat Portland Cement clinker.
