1 Miller, Jan D.Anisotropic character of talc surfaces as revealed by streaming potential measurements, atomic force microscopy, and molecular dynamics simulationsA study of the interfacial properties of the basal plane and the edge surfaces of talc is described in this paper. The isoelectric-point measured at the two different crystallographic planes by the streaming potential method was found to be similar and exists at about pH 3.0. In the case of the edg...Streaming potential; Scanning electron microscope; Atomic force microscope2006
2 Miller, Jan D.Atomic force microscopy investigation of interaction forces between polyethylene and asphaltene surfacesMany petroleum-derived asphalts used for road construction exhibit poor rheological properties. These properties of asphalt can be improved by addition of various polymer fillers to the asphalt blend. Recycled polyolefines, especially polyethylene and polypropylene have been used as the asphalt mo...Asphalt; Rheology; Polyolefins2006
3 Miller, Jan D.Experimental evaluation of a mineral exposure model for crushed copper oresCopper mineral inclusions dispersed in crushed ore particles have a certain size distribution (grain-size distribution). For efficient heap leaching processes, the crushing plant should be designed and operated to crush the ore to an appropriate particle-size distribution so that copper mineral grai...Grains; Particles; Distribution2006
4 Rajamani, RajOnline SAG mill pulse measurement and optimization semi-annual technical progress reportThe grinding efficiency of semi autogenous milling or ball milling depends on the tumbling motion of the total charge within the mill. Utilization of this tumbling motion for efficient breakage of particles depends on the conditions inside the mill. However, any kind of monitoring device to measure...2006
5 Miller, Jan D.Pilot-plant evaluation of a water insoluble hydroxamic acid collector for single stage flotation of Florida phosphate rockRecent laboratory results have demonstrated that selective flotation of phosphate rock can be achieved in a single stage with improved separation efficiency when compared to the standard double float process. The new reagent chemistry is based on the use of a water insoluble alcoholic solution of ...Phosphate rock; Flotation; Double float; Separation2006
6 Miller, Jan D.Trithiocarbonates for PGM flotationSmall replacements of C12-trithiocarbonate (C12-TTC) for dithiocarbonate DTC)/dithiophosphate (DTP) in a reagent suite for the flotation of platinum group metals (PGM) have significantly improved the rejection of gangue. Coupled to this is an improvement in kinetics, grade and recovery of PGMs. In ...2006
