Material Flow Balance for Bauxite Grinding & Pre-Desilication Units

Hi Friends,

You will appreciate the efforts put by us in exchanging views on many complicated technical issues pertaining to Bauxite, Alumina and Aluminium metal. Now, we have reached to a reasonably high level of discussions on the subject. The project engineering involving sizing of equipment as well as pipelines, material flow calculation for each stream is a must. Thus, we thought of sharing the simplified  methodology for carrying out material flow balance calculations for a typical 1.0 Mtpa Alumina refinery. 

In present post, we have just presented a sample of material flow balance for Bauxite grinding and Pre-desilication units of Alumina refinery. 

Using basics of Chemical engineering and mineral processing techniques, material flow balance for all units followed by thermal energy balance calculations for the plant may be developed by individuals for taking up assignments pertaining to design, engineering and execution of Alumina refinery. 

Hope, you will like this approach of systematic learning of process and plant design calculations for setting up Alumina refinery of any capacity.

Please put your views / suggestions / remarks / comments, if any.

Regards.
