A Concept Scheme for the Joint Processing of Red Sludge and Largetonnage Waste from the Oil and Petrochemical Industries
https://doi.org/10.18412/1816-0395-2023-2-26-31
Abstract
It has been established that in the process of joint heat treatment of a mixture of red mud – quartz-leucoxene concentrate, a change in the chemical composition occurs with the formation of pseudobrookite, which has an increased chemical activity compared to the original quartzleucoxene concentrate. It has been established that the product of the combined heat treatment of red mud and acid tar consists of a mixture of aluminum, iron, and titanium sulfates that are readily soluble in water. Calcium sulfate and silicon compounds have been isolated as insoluble impurities. It is confirmed that in order to achieve the maximum degree of interaction, the mixture of red mud and acid tar must be heated at a rate of no more than 1–2 °C/min until 550 °C and time 60 min.
