Abstract : Does not produce sodium aluminate locally, but are providing local industry needs of the ditch article by imports from abroad. The parents of bauxite ore contains 40-60% alumina and not more than 7% for the bumper Salka t because the main product of sodium aluminate. And this raw land available in the UK in very limited quantities. The research aims to study the possibility of producing sodium aluminate locally to meet the needs of national industry and Lalla Almrobat Stkhaddamat only other child using the materials found in the national territory of the Kingdom instead of bauxite ore few local presence in a way you Dr. Alklsna with lime. Has been activated child kaolin National contain 4 and 29% oxide aluminum by heating at a temperature of 700 C for one hour was then knead roasting kaolin with calcium carbonate and then address the output of roasting a solution of carbonate Alsod day because Stkhalo am not the Lumina in the child in the image of sodium aluminate. Has been in the roasting step larg Ther study the following factors on the extraction of the Lumina, but a child of kaolin National The temperature of roasting from 1200 to 1400 degrees Celsius - the time of roasting half to three hours - and the percentage molecule because oxide calcium to the total Aksidi only to Omenyum and silicon of 5 and 2 to 0 and 4 and massage under the conditions of extraction constant equal to the temperature of 70 ° C and a time of half an hour, and the proportion of molecular oxide, sodium oxide, except for Omenyum equal to 2 and 2. The laboratory study results showed that the extract alumina increases with the degree of Alklsna in the range of 1250 to 1350 degrees C and then at least increase the degree of Alklsna to 1400 degrees Celsius. The study results showed that the effect of time on the degree Alklsna Astkhala p. alumina of the child depends on both the temperature and the ratio of molecular Alklsna because calcium oxide to the total Aksidi only to Omenyum and silicon. The study Kdlk explained that by increasing the ratio of molecular to calcium oxide to the total Aksidi Omenyum and only to the Silicon Stkhalas only increases with the degree of roasting temperature to 1300 ° C and that this Alta Ther depends on both temperature and time Alklsna. It was recommended Ba use of the conditions of roasting of 1350 ° C and a time clock for both temperature and time of roasting and the proportion of molecular not master of calcium to the total Aksidi only to Omenyum and silicon equal to 5 and 2, where the degree of Ostkhala am only Lumina of the child is equal to 23 and 48% under pit conditions, For a step, but Stkhala PO solution carbonate Alsod on The results of the study larg Ther relatively small for both temperature and time, but Stkhala r and also for the proportion of molecular No, master of sodium to aluminum oxide on the degree Ostkhala p. alumina of the child where she was a Qusay degree Ostkhala am the alumina from a child is equal to the local kaolin 55% 90 C Anz conditions of temperature and 3 hours of time, but Stkhala am and because molecular ratio of sodium oxide to the oxide only to Omenyum equal to 0 and 3. The results of the study but decline relative because Stkhala am only to Lumina the form of sodium aluminate from the raw baby kaolin National Ba use of the way Alklsna lime and recommends examining the appropriate method Alklsna with lime and soda alternative way Alklsna with lime only to produce sodium aluminate of a child kaolin national
