1993-11-1 Flotation was used to achieve improved separation of magnetite from the float and sink products obtained from heavy medium separation and to reduce the load of the medium cleaning circuit. The investigation was carried out in two successive phases. In the first phase, tests were performed on in-plant samples from the Homer City Coal Prepation plant to determine what effects variables such as ...
