Physicochemical Studies of the Decomposition of Mineral Aluminum-Containing Raw Materials by Acidic Methods
Abstract—The chemical and mineral compositions of the Kanash clay and sands from the Chuvash deposit are studied. The results of search for the decomposition of the Kanash clays by sulfuric and hydrochloric acids are presented for the further use of the prepared solutions as coagulants for the purification of drinking and waste waters. The preliminarily calcined clay is subjected to leaching and sulfating roasting followed by water leaching.
期刊介绍:
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
