Consumption of refractory grade bauxite within the market economies of the world is currently estimated to be between 700,000 and 800,000 metric tons per year and, combined with demand from the U.S.S.R. and the People's Republic of China, total world consumption of bauxite for use in refractory applications is thought to be in excess of 1 ...
A typical Bayer plant generates from 1 to 2.5 times as much red mud as alumina produced, with an average of 1.75 tonnes of red mud per tonne of alumina (this ratio is dependent on the type of bauxite used in the refining process and the extraction conditions).
Bauxite. Bauxite is known mainly as the ore from which aluminum is smelted but it has large use also in the manufacture of artificial abrasives and as a basis for certain chemical industries. A small amount is used for refractories and for other purposes.
Contact Us. Rotary Scrubbers are used to wash crushed rock, mineral ore, sand, gravel, and building stone which with high content of clay, powder or soil. Prominer can provide heavy duty module rotary scrubber system that is cylindrical drums with internal lifters and supported by four trunnion rollers at both end as well as trust rollers.
A Bayer process plant is principally a device for heating and cooling a large recirculating stream of sodium hydroxide solution through a temperature range of up to 500oF per cycle. Liquor flow rates of 5,000 to 10,000 gpm are common in the newer plants. Bauxite is added at the high temperature point, red mud is separated at an intermediate ...

Alumina Technology (CETI Enterprises) Hi Friends, We are planning to publish a book on Alumina Technology covering various technical aspects with emphasis on process & design of Metallurgical and Non-Metalurgical (Speciality grades) Alumina Plants including Byproducts. We have structured a Draft Table of Content for the purpose.
Adopting the process of washing bauxite in the beneficiation plant can reduce caustic soda consumption and equipment and piping scale in the alumina refinery (OPEX), and consequently the payback for the beneficiation plant can be less than 3 (three) years. Besides the caustic consumption reduction, the beneficiation plant decreases the refinery ...
