RI 5528 Kerosine Flotation Of Coal: Semicommercial Studies Of Cell Performance ? Introduction And Summary

Since the turn of this century, there has been increasing interest in the application of flotation processes to the beneficiation of finely divided minerals of various types, This is reflected by the large numbers of papers dealing with various aspects of this problem published annually both in this country and abroad. For the most part, such papers fall into one of three categories: 1. Those concerned with achieving, by various chemical and/or physical means, a set of conditions under which certain particles become potentially floatable while others do not. 2. Descriptive studies of plants and pilot plants effecting separations between such particles. 3. Studies of the effects of certain design and operating variables on the rates and efficiencies with which such separations can be effected.
