Abstract
Under the conditions of preliminary treatment during the preparation to annealing of a mixture of Tuva clays with the dearsenation cake of the Khovu-Aksy dump sludge, the material was found to undergo a chemical process that forms nepheline. Based on the calculated Gibbs energies of the reactions, it was concluded that the reaction occurs at the minimum number of components in the system: silicate Na4Mg2Si3O10–kaolinite (kaolinite + orthoclase).
