This was a unique idea; to use a size separation device in a mineral separation. As metallurgists, we were taught in school to use any
The pilot mill used was 44 cm i.d. and 60 cm i.l. with a volume of 91,250 cm and was fitted with six one-half inch
To study the effects of collector and hydrogen ion concentrations on the floatabllity of sulfide minerals, a series of flotation experiments were conducted in which
Over the last few years there has been an intense effort to identify lixiviants other than cyanide for gold and silver leaching. Bromide and iodide also
Production pellets from each Minnesota taconite operation were obtained for baseline metallurgical testing. Concentrate from several of the operations was obtained for more intensive studies.
Froth flotation of minerals is one of the dominant concentration processes available today. By this process, finely divided mineral particles, within a pulp, separate according
Dust measurements in mines clearly indicated that the major mineral dust exposure is due to loading and transport of the ore from the mining areas.
Ball mill shape factors in the period prior to 1927 averaged 1.1/1 for 29 center discharge mills and 1.0/1 for 30 peripheral discharge mills. With
We present the results obtained in a study of the residence time distributions of solids and liquids in two and three phase systems in a
Very few mineral properties spend their entire lifespans from discovery to depletion in the hands of one owner. More likely, properties will have several owners,
