The following paper deals with the problems that have arisen in the application of the flotation process to the beneficiation of non-metallic ores by flotation. The most important of these ores are listed and the commercial specifications of the desired products are given. The problems caused by the complexity of many of the raw ore … Read more
The concentration of fluorspar ores by flotation is well established but the treatment of lead-barite-fluorspar ores has long been recognized as a difficult process generally resulting in unacceptable concentrates with relatively poor recoveries. Intensive research on this problem is continually being conducted to develop favorable reagent combinations and conditions suitable for treating such ores. The … Read more
Barite (barium sulphate) often occurs as large veins or beds, as gangue mineral in various mineral veins, in limestones, sandstones and like deposits. The ores are generally low grade and require concentration by flotation to meet market specifications. Barite, which has the ability to influence other materials with its basic characteristics, makes this heavy spar … Read more
