Abstract
Abstract
| The separation of feldspars from quartz has been the subject of numerous studies since 1930 and the flotation process so far proved to be the most suitable method. In the conventional process, feldspars are separated from quartz using a cationic collector and hydrofluoric acid as an activator of feldspars. There is no general agreement on the mechanism of fluoride activation of feldspar surfaces and the role of fluoride ions is briefly discussed. The use of HF is no longer acceptable due to environmental and health problems, and a few new reagents schemes have been reported. The available evidence shows that the success of these new reagent schemes is very limited. A new reagent scheme which is environmentally safe and cost effective for the separation of feldspars from quartz is yet to be resolved. |
