Abstract

A method of producing portland cement using the wastes of enrichment of polymetallic ores of "Achpolymetal" (Kentau, Kazakhstan) in the amount of 0.5 to 2.5% as a mineralizing additive in the raw mixture is proposed. This allows the clinker to be produced at a lower temperature (1300–1350°C), resulting in lower fuel consumption and higher furnace productivity. The experimental clinker is better subjected to grinding, the electric power consumption for grinding cement decreases, the grinding bodies of cement mills decrease. In the waste, there are catalytic and modifying elements. Studies have shown that in the no-added raw mix the clinker formation processes are completed at 1450°C. When 0.5 to 2.0% of the tailings are introduced, the complete binding of CaO is completed at 1400°C, with the addition of 2.5% of tailings, lime binding is completed at 1300 or 150°C lower than in the control non-additive raw mixture. In clinkers, only 1.09–1.32% of free lime remains. The strength of cement when introduced into the raw mix from 0.5 to 2.0% of barite waste is increased. The compressive strength at 28 days of age for cement with an optimum dosage of 1‒2% of the tail increases from 414 kg/cm2 to 430‒432 kg/cm2 or by 3.9‒4.3%. Similarly, the strength of steamed samples increases by 4.7‒5.7%.
