The Bayer process started gaining importance after the invention of Hall-Heroult aluminium process.

Mass balance - Wikipedia

A mass balance, also called a material balance, is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique. The exact conservation law used in the analysis of the system depends on the context of the problem ...

Material balance equation of shale gas reservoir ...

As the formation pressure drops during the development process of shale gas reservoir, the effects of stress sensitivity and matrix shrinkage occur. Stress sensitivity effect decreases the porosity of reservoir formation, while matrix shrinkage effect increases the porosity. Therefore, the porosity will be influenced by the combined effect of both stress sensitivity and matrix shrinkage, which ...

Solvay process - David Darling

The Solvay process is an industrial process, also known as the ammonia-soda process, for the manufacture of sodium carbonate (see sodium). Sodium chloride (common salt), ammonia, carbon dioxide, and water react to give precipitated sodium bicarbonate, which on heating gives sodium carbonate and carbon dioxide for recycling.

The Chemistry and Processing of Jamaican Bauxite

The first commercial extraction of alumina (Al 2 O 3) from bauxite has been attributed to Henri Sainte-Claire Deville in about 1854.. Soon after this, in 1888, Karl Joseph Bayer described what is now known as the Bayer Process, which led to a dramatic reduction in the cost of aluminum metal.

The Bayer process is the most main technique to produce Alumina. The material balance calculation is the dynamical equilibrium computation process, which keeps to conservation of mass, achieves the material information integration about each technologic node, including the whole chemic reaction process which is from Alumina ore input to Alumina output.

Chapter 2. Production and Processing of Aluminum

The starting material for electrolytic smelting of aluminum is pure, anhydrous alumi-num oxide (Al 2 O 3) called alumina. In the Western World, the Bayer 1 process, invented in the 19th century, is by far the most important process used in the production of alumi-num oxide from bauxite. The process has been refined and improved since its inception.
