ABSTRACT: This paper investigated the production of alumina from Nawan kaolin by acid leaching with sulfuric and hydrochloric acids. Kaolin was calcined at 850°C and was leached with 6 M acid at 90°C, 5M NaOH followed by HCl solutions were added to the leaching liquor, and the precipitated aluminum hydroxide was converted to alumina by calcination at 900°C.

Following Meissen and Sèvres products, British potters began to use china clay or kaolin, when in 1768 William Cookworthy, a Plymouth chemist, proved the potential of the kaolin reserves of Cornwall. Surprisingly, many of these are inorganic minerals; for example talc and kaolin or china clay.

indium and tin extraction in the presence of acidophilic microorganisms. Within 35 days, using 9K medium, 55.6% of indium was bioleached, whereas the chemical leaching resulted in a value of 3.4%. Leaching efficiency of tin was 90.2% on the 14th day of the experiment for the biological system 9K and 93.4% on 21st day of control leaching.
