Major Facilities for Processing Gibbsite-Boehmite Mixed Bauxite

Hi Friends,

In earlier post, we have discussed about the Technology for processing of gibbsite-boehmite mixed bauxite in Alumina refinery. Here in present post, we will discuss briefly about the major technological and services facilities required for setting up new Alumina refinery for processing of gibbsite-boehmite mixed bauxite. Considering the recent developments and efficiency of operative Alumina refineries in the World operative on commercial scale have been taken in to account to highlight the major facilities for forthcoming plants are given below-

Adoption of Double digestion system, Pressure decantation and Two stage continuous precipitation are the proven process techniques which attribute in marginal reduction in the energy consumption compared to other established process technology for gibbsite-boehmite mixed bauxite in the World. A few Alumina refineries adopting this technology are operative and under execution as well. As sizing calculations for all these equipment and facilities have direct bearing on capital investment of the project, thus it requires systematic approach and inputs from experienced experts in the field while designing and execution of plant.
