PROCESS FOR THE RECOVERY OF MINERAL VALUES BY FLOATING IN FOAM |
| abstract |
This invention relates to a flotation process in which selectivity for the valuable mineral is improved by reducing the silica or siliceous gangue through the use of a hydroxy-containing compound such as an alkanolamine. The process is useful in the flotation of mineral oxides and in the flotation of sulphides. |
