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 ranging from about 1,000 to less than about 10,000.

Abstract: New and improved processes and compositions for use in flotation recovery of metal values from base metal zinc sulfide ores are disclosed. The collector compositions for froth flotation of metal sulfide minerals comprise the combination of 1) at least one allylalkylthionocarbamate compound having formula (I), wherein R is a C2 to C8 alkyl radical, preferably R is an isobutyl group, and 2) a xanthate having formula (II), wherein R' is a C2 to C8 alkyl radical, preferably a C4 radical. More preferably, the C4 radical of the xanthate is a butyl or isopropyl group. Preferably, the concentration of allylalkylthionocarbamate to xanthate is a ratio of from about 1:99 to about 50:50 percent by weight.
