ABSTRACT:
The processing of bauxite in the Bayer Process results in the formation of titanaceous, siliceous, and other scale on equipment and apparatus such that a great deal of time and effort is spent in order to maintain the process at its height efficiency by reducing or eliminating the same. The scale is treated, reduced, altered, etc., according to the present invention by the use of hydroxamated polymers having weight average molecular weights of over about 10,000.
