Miller, Jan D.; Lin, Chen-Luh | Flotation recovery of high-purity gibbsite concentrates from a Brazilian bauxite ore | Recently research efforts have been made to obtain a high-purity gibbsite concentrate, suitable for first-class alumina refractories, from a Brazilian bauxite ore containing gibbsite (50%), quartz (35%),and kaolinite (15%). Detailed polished-section microprobe analysis was used to describe the ... | Gibbsite; Alumina | 1990 |

Miller, Jan D. | Molybdenite flotation from copper/molybdenum concentrates by ozone conditioning | Typically, rougher molybdenite flotation and recovery from bulk copper/molybdenum concentrates involves the use of alkalisulfides, Nokes reagents, cyanides, oxidants, and/or thermal treatment to depress copper sulfide minerals. The bulk copper/molybdenum feed generally varies from 0.2% Mo to 1.0% M... | Molybdenum; Copper; Flotation; Ozone conditioning | 1990 |

Miller, Jan D. | Spectroscopic analysis of passivation reactions for carbonaceous matter from carlin trend ores | Abstract. Three different refractory carbonaceous gold ores from the Carlin operation in northeastern Nevada were investigated to characterize the effect of passivation treatments on the nature of the carbonaceous material. The carbonaceous material was chemically isolated from the ores and pass... | Gold; Chlorine; Cyanidation | 1990 |
