theory and practice of bauxite x-ray sorting | springerlink,that is why, for many years, scientists have been studying the problem of bauxite beneficiation. complex mineralogy of bauxite, high content of alumina and process limitations often make traditional beneficiation techniques ineffective. the use of different kinds of radiation jointly with sorting techniques has been intensively studied in russia, that resulted in development of new direction of beneficiation —.alumina production in russia part i -,hence, in russia's transition to a market economy, the first priority of alumina producers is to optimize power efficiency at the plants. for the production facilities that treat bauxite, the plan is to reduce total heat consumption by increasing the digestion temperature and better contain the heat within the processing circuit..
