These slimes are the accumulation of the finer particles of the ore during the mill­ ing prooess, and their zinc content is well worth considering. The praotice in the past has been to sluice these slimes into the tailing pond, as no economical method of saving the zinc had been employed. The objeot of our experiment was to economically extract from these slimes by :flotation, a product of" suff­ icient zinc oontent to be of commercial value. The slime we used was from the S. J. Ramage Mill No.6. West Joplin. It was received dry, and used that way for all experiments. We performed ten experiments in the Mineral Sep­ aration machine, with very little suocess. This was due, we think, to the fineness of the ore. The results of these ten experiments were so poor, that we did not reoord them. The results reoorded in this thesis are from exper­ iments performed in the Callow pneumatic flotation machine in the flotation laboratory of the Missouri Sohool of Mines and Metallurgy. -2- In determining the nature of the are, such charact­ eristics as its acidity or alkalinity, chemical analysis, physical analysis, and screen analysis were determined.
