Pres At Metall Soc AIME 113th Ann Meeting Los Angeles, California, 1984 Feb; :11 pages
As part of a program to devise alternative technologies for producing alumina from domestic resources, the Bureau of Mines investigated the leaching of calcined kaolin clay to form basic aluminum chloride solutions. Bench-scale experiments were conducted for single-stage batch leaching with alcl3 solution and three-stage counter current leaching with substoichiometric hcl. Variable conditions of clay calcination and leaching were studied to determine their effects on aluminum extraction and pregnant liquor composition.
