Thus, the C.S. varies from zero for no separation to 1 for perfect
separation. According to Norris and Yordan (9), the C.S. varies
from 0.3 to 0.75 in the case of beneficiation of kaolin by froth
flotation.
The co-collector usage circumvents the use of activators such
as the divalent salts normally required with oleic acid (10). This
is an interesting phenomenon and merits further investigation.
The advantage of prior addition of hydroxamate to condition
the kaolin is that any type of deflocculant can be used on this
