Miller, Jan D. | Bench scale flotation of alunite ore with oleic acid | Alunite [KA13(SO4)2(OH)6] is a promising non-bauxitic aluminum resource, the domestic reserves of which are estimated to be 800 x 106 tons at 35 percent alunite. The major gangue mineral associated with alunite is quartz. The thermochemical process that has been developed for treatment of this ore... | Mesh; Separation; Liberation | 1980 |

Miller, Jan D. | Pilot-plant evaluation of a water insoluble hydroxamic acid collector for single stage flotation of Florida phosphate rock | Recent 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; Separation | 2006 |

Miller, Jan D. | Screening and classification | The processing of minerals almost invariably involves the reduction in size of the minerals contained in an ore to effect liberation of disseminated values or, in other instances, to effect increased surface area. Separation of solids according to size usually is undertaken to promote maximum produc... | Mesh; Mechanical; Separation | 1973 |
