Alum Ferric Non Ferric

Bauxite is ground in the pulverizer to 90 passing through 200 mesh and elevated to Batch Hopper through Bucket Elevator. Measured quantity of water is to be taken into the Lead bonded reactor and slowly concentrated Sulphuric acid is to be added in the reactor. After getting the required temperature in the reactor, slowly the ground bauxite is added . After the addition of measured quantity of Bauxite/Alumina Hydrate, the Agitator is kept on for about 45 minutes then the solution is dumped into the settling tank.
