A method of processing alunite or alkali free
A method of processing alunite or alkali free aluminosilicate ores on potassium alum and aluminum chloride, characterized in that the crushed ore is subjected to calcination, the calcined ore is treated with sulfuric acid, the resulting solution is separated from the solid residue of ore, followed by crystallization from him, potassium alum byAlunite has been described both by the chemical formula [KAl3(SO4)2(OH)6] and by the chemical formula [K2SO4·Al2(SO4)3·2Al2O3·6H2O] The latter gives an erroneous impression that water is structurally associated with the mineral The former representation is therefore, to be preferred It is more in conformity with the crystal structure of alunite The structure of alunite is similar toAlunite Crystal Chemistry Mineral Processing & Metallurgy
