Pneumatic ore concentration

Abstract

"The concentration of lead and zinc ores by means of air is practically an unexplored field, although the subject is by no means a new one. Considerable research work has been done and several methods, processes and machines have been developed, but little or nothing has been accomplished towards making air separation a success. the lack of success has been due mainly to two reasons:- (1) That very little has been known about the internal conduct of air currents, and (2) that nearly all methods and machines so far worked out have presupposed the fact that the ore to be separated should not come into direct contact with the air currents. In this thesis the work will be done under the assumption that air currents act or can be made to act with much greater regularity than has hitherto been supposed"--Introduction, page 1.
