| Résumé : | The research described in this paper reveals new prospects of utilizing grinding fines of Belgian porphyric rocks. It is shown that it is possible to recover from these fines concentrates which are rich in feldspars and micas of interest to various sectors of industry, thus adding value to rocks with an intially very low economic value. This is done by means of differential flotation in an acid circuit in the presence of an amine collection. |
