According to the alumina production process, the production cost of alumina is roughly composed of the following:
(1) Raw materials: bauxite, limestone, alkali (soda ash and caustic soda), etc.;
(2) Auxiliary materials: steel balls, grease, conveyor belts, etc.;
(3) Fuel and power costs: power consumption, steam consumption, water, heavy oil, coke, etc.;
(4) Other costs: labor, manufacturing, management expenses.
During this period, bauxite is the primary raw material and the primary source of cost for production of alumina. The production of a pound of alumina requires about two pounds of bauxite (due to the different grades, the amount of bauxite needed for the tons of alumina is different).
Versa-Matic introduced the latest gas E3 alumina slurry pump, compared to the previous product, it not only has zero-resistance delivery reliability, greatly reducing the residence time of the mud in the pump, etc. In addition it In the delivery of large flow of mud when it is more than the previous products can not be achieved with high performance. The new E3 pump consists of an air valve system, which eliminates the clogging, freezing and lubrication problems that the mud creates during transport. The new pump is designed to provide good sealing performance, so it delivers up to 90% efficiency while delivering high flow solids.
[Alcoa China] Although electrolytic aluminum, aluminum chloride and aluminum ingots all seem to have aluminum, they are different chemicals.
Electrolytic aluminum is obtained by electrolyzing bauxite as an electrolytic material and adding cryolite as a catalyst, and now aluminum is generally obtained by this method. Alumina is an oxidation product of aluminum and can be obtained by burning in oxygen or heating in air. Alumina is added to the cryolite and electrolyzed to form aluminum. The aluminum ingot is made by casting an aluminum rod in a molten state into an ingot shape for easy transportation and metering. The main differences between electrolytic aluminum and aluminum ingots are different from their shapes.
