A method of alumina production based on hydrochloric acid processing of kaolin clays from the East Siberian deposits was studied. Hydrochloric acid leaching was carried out at 160 °C. The leaching solution was subjected to a twostage crystallization of aluminum chloride hexydrate (ACH). The precipitated crystals were calcinated in air at a temperature above 800 deg;C to produce alumina.

Nigeria is the highest consumer of aluminium in Africa but lacks bauxite deposits. The replacement of bauxite alumina with other alumina bearing resources (clays in particular) has been proposed. The present study investigated the thermal treatment required to activate Edda clay from southeastern Nigeria for optimal leaching of alumina. The clay is composed mainly of kaolinite and quartz ...
The company is constructing an HPA plant at Johor in Malaysia. Mitsubishi has entered into offtake agreement for the first 10 years of production. The plant will be fed by the company''s kaolin mine near Meckering in WA. It hosts a reserve of 30% Al2O3 within a resource of 30% Al2O3. Andromeda Metals (ASX: ADN)
percentage of aluminum oxide and low percentage of impurities is the kaolinitic clays. It is thought as a suitable substitute for bauxite from which alumina of high purity can be obtained. Several sintering and acidextraction processes have been investigated for the production of alumina from kaolin .

Metakaolin (MK) is one type of calcined clay and it comes from the calcination of kaolin clay, and there have been some interests in the use of MK in recent years (Siddique and Klaus, 2009). For example in the United Kingdom, the coalfired power industry will come to close in the next 10 years and fly ash will cease to be generated.
The leached clay residues were analyzed for Fe 2 O 3, TiO 2, and Al 2 O 3 to ascertain the quantities of these oxides remaining after leaching (Table 5). The Al 2 O 3 was reduced to a range of to percent in the 650°Ccalcined leached residues. The Fe 2 O 3 values ranged from to percent in the 650°calcined residues. Iron content is of interest because ferric iron is the ...
