1 Miller, Jan D.Adsorption mechanisms in nonmetallic activation systemsAdsorption of lead and ferric iron on quurtz and alumina is presented as a function of pH. Only the hydrolyzed species of these metal ions, FeOHt+ and PbOH', adsorb significantly on each of these minerals. Zeta potentials of quartz were measured as a function of pH in the presence of various additio...Ferric iron; Quartz; Lead; Alumina; Adsorption; pH (Chemistry)1970
2 Miller, Jan D.Hydroxamate vs. fatty acid flotation of iron oxideData were obtained with hematite with octyl hydroxamate and oleate as collectors to determine the mechanism of collector adsorption and also to establish the roles that conditioning time and temperature assume in this system. The presence of hydroxy complexes of iron are apparently necessary for che...Iron ore; Iron; Fatty acid; Hydroxy complexes1970
3 Miller, Jan D.Minerals beneficiation in '69 steps up tonnage, engineering, environmental control and automation: size analysis and flotation chemistry highlighted by basic science researchersThe application of computers to the control and study of mineral processing operations such as grinding, classification and notation has created an interest in simulation studies of these operations with mathematical models. Evidence of this interest is confirmed by papers presented at the 1969 Int...Mineral processing; Computer simulations; Mathematical models1970
4 Brown, Francis HaroldPliocene/pleistocene formations in the lower omo basin, southern EthiopiaFollowing a two month geological reconnaissance by one of us (FHB) in 1966, four seasons of fieldwork by members of the Omo Research Expedition has added greatly to our previous, scanty knowledge of the late Cenozoic history of the lower Omo basin in southern Ethiopia. Eduard Suess (in: von Hohnel ...1970
