Abstract : Aluminum metal is one of the most important metals at the present time is used in many industries and industrial products. And the aluminum industry are two main phases, where phase involves the initial production of pure alumina (aluminum oxide) of the raw materials while the second phase reduction of alumina into aluminum metal. The global production of alumina about 35 million tons are produced annually, most of the bauxite ore in a Ba seen. And other important uses include the manufacture of alumina grinding - chemical industry - refractories and ceramic fiber. Bauxite ore contains about 55% alumina and less than 7% silica. The discovery of the limited reserves of crude in the territory of the Kingdom, and therefore it is important for research to be Wael ore bauxite. The raw silicate only to Omenyum which Tto fled in abundance in the territory of the Kingdom, especially a child kaolin Saudi promising alternative for production, but Guetsada Lalla Lumina high focus - It contains kaolin national high proportion of alumina and rates relatively low oxide of iron and partly of an impact on recovery, but the Lumina . The aim of the research project presented to study the possibility of producing alumina from ores child widespread national presence in the land of the Kingdom instead of bauxite ore little presence. The study will be conducted laboratory to extract alumina from the national child Elsna then the transactions abyss of old age Atic acid and the appointment of a preferred, but conditions Stkhala AM. The study will be the larg Ther washing of the acid is not persistent in the amount of silica in the perpetual solution. Will be studied purification of the solution resulting from dissolving in the acid salts of iron dissolved by an alum crystal, ammonium, and only to Omenyum where you're not studying the larg Ther different factors on the development of ammonium alum and aluminum to achieve the most suitable conditions for crystallization will also be calcination alum for the alumina clean. In light of the results will be proposed an appropriate way to obtain alumina from ores national child.
