Figure 1 Schematic flow diagram illustrating the main process steps in designing a successful and viable aluminium rolling plant A Methodical Approach Figure 1 highlights the need to optimise products and volumes in order to make best use of the chosen equipment and to increase the viability of the plant.
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.
The next stage in the production chain is the processing of bauxite into alumina or aluminium oxide - Al 2 O 3 - a white powder.The most common process for making alumina from bauxite is the Bayer process which was first discovered over 100 years ago but is still in wide use today.
The process begins with an aluminum ingot which was cast to be about 30 inches 76 cm thick then rolled into a thin sheet. The first step in the actual manufacture of the can is to cut the sheet into a circle called a blank that will form the bottom and sides of the can.

Quick Read. Primary production is the process by which alumina is smelted to pure aluminum metal. The HallH roult process simultaneously discovered in 1886 by American Charles Martin Hall and Frenchman Paul H roult continues as the main industrial process by which primary aluminum is made.
A process flow diagram of this facilitys operations including representative production levels has been provided in Figure 5-2. As illustrated by the diagram hand wash floor wash and employee shower waters are combined with regulated casting and forming process wastestreams prior to treatment.
