Miller, Jan D. | Effect of pH on pulping and flotation of mixed office wastepaper | The effect of pulping reagents on the deinking flotation of laser-printed wastepaper was investigated with regard to the removal efficiency of toner and mineral filler particles at different pH values. These results show that caustic pulping causes the toner to be released from the fibres as larger... | Wastepaper; Deinking; pH values; Pulp production processes | 1999 |

Chandran, Ravi | Evolution of microstructure and phases in in-situ processed Ti-TiB composites containing high volume fractions of TiB whiskers | A series of titanium composites, with varying volume fractions of titanium monoboride (TiB) whiskers, were made by mixing various proportions of titanium (Ti) and titanium diboride (TiB2) powders followed by hot pressing. The phases present were identified by x-ray diffraction. | Morphology; diffraction; relative intensity | 1999 |

Miller, Jan D. | Free and emulsified oil removal by bubble accelerated flotation (BAF) | Operational data from full-scale field applications and pilot tests using the Bubble Accelerated Flotation ( B A R system for the treatment of wastewater are presented. The compact BAF system based on the air-sparged hydrocyclone technology was designed to remove pollutants from industrial waste and... | Bubble accelerated flotation; Air-sparged hydrocyclone; Flocculants; Oil-in-water emulsion | 1999 |

Miller, Jan D. | Internal reflection spectroscopy for FTIR analysis of carboxylate adsorption by semi-soluble salt minerals | Flotation chemists have long sought to unravel the mechanisms of carboxylate collector adsorption by semi-soluble salt minerals. In particular, the adsorption density of adsorbed carboxylates, adsorption kinetics, speciation (chemisorbed, physisorbed), orientation, and conformation are of interest.... | Carboxylate collector adsorption; Salt minerals; Internal reflection spectroscopy | 1999 |

Miller, Jan D. | Treatment of cyanide by using the Mexican modification of the Merrill-Crowe process | Cyanide consumption can be a major factor which contributes to operating cost for cyanidation. Also after extraction and recovery of precious metals substancial amounts of cyanide are delivered to tailings ponds which creates environmental problems due to the toxicity of cyanides. In this regard, th... | Cyanidation; Merrill-Crowe process; Air-sparged hydrocyclone; Cyanide recovery; Cyanide destruction; Chlorine dioxide | 1999 |
