to aluminium oxide. A Bayer Process plant is principally a device for heating and cooling a large re circulating stream of caustic soda solution. Bauxite is added at the high temperature point, red mud is separated at an intermediate temperature, and alumina is precipitated at the low temperature point in the cycle.

A schematic flow diagram for the proposed beneficia-tion plant is given in Fig. No. 1. In the proposed in-stallation, the run-of-mine ore would be fed to a Double Pitman Jaw Crusher by means of an apron conveyor. The crushed bauxite would be first chuted down to a scalping screen where the larger lumps up to 2-inch size would be separated.

of process-based diagrams to which P&IDs belong. The block fl ow diagram (BFD) (Figure 1) is a very simple diagram that can condense an entire process onto as little as a single sheet. More detailed information can be found in the process fl ow diagram (PFD), which is considered the precursor to the P&ID. Typically, the PFD is used by plant
ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.

Over the period 2003 to 2006 the bauxite feed to the Kirkvine refinery has undergone a dramatic change in composition with severe impact on plant performance. Surprisingly, the change in composition is not directly evident from the XRF analysis of the major elements, which showed that the total Al 2 O 3, Fe 2 O 3 and LOI contents of the bauxite remained largely unchanged.
Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult process.Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery.. This is an electrolytic process, so an aluminium smelter uses huge amounts of electric power; smelters tend to be located close to large power stations, often hydro-electric ...
