Mineral collector compositions and processes for making and using same |
| abstract |
COLLECTOR COMPOSITIONS OF A MIXTURE OF A C6 TO C22 FATTY HYDROXAMIC ACID AND AN OIL FOR USE IN THE REMOVAL OF IMPURITIES FROM MINERAL ORES BY THE FROTH FLOTATION METHOD. THE COLLECTORS ARE PREPARED BY REACTING AN ESTER OF A C6 TO C22 FATTY ACID WITH A HYDROXYLAMINE SALT AND A BASE IN THE PRESENCE OF AN OIL AND WATER TO PRODUCE AN ALKYL HYDROXAMATE SALT; ACIDIFYING THE ALKYL HYDROXAMATE SALT, FORMING AN ORGANIC LAYER AND AN AQUEOUS LAYER, WHEREIN THE ORGANIC LAYER CONTAINS A C6 TO C22 FATTY HYDROXAMIC ACID SUBSTANTIALLY FREE OF STARTING ESTERS AND HYDROLYSIS AND TRANSESTERIFICATION PRODUCTS OF THE ESTER; AND SEPARATING THE ORGANIC LAYER FROM THE AQUEOUS LAYER TO PROVIDE A COLLECTOR COMPOSITION OF THE C6 TO C22 FATTY HYDROXAMIC ACID AND THE OIL. |
