Reagents in iron ores flotation - ScienceDirect

Feb 01, 2005 · 3. Cationic collectors. Primary fatty amines, utilised in the pioneer USBM process, are no longer employed in the flotation of iron ores. They were modified with the insertion of the polar group (O–CH 2) 3 between the radical R and the polar head NH 2 of the primary amine. Due to the presence of the covalent bond C–O, characteristic of the organic function ether, reagents belonging to this ...

Froth flotation - Wikipedia

Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its antiquity. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven work-place applications, especially at Broken Hill, Australia, that brought the technological innovation known as “froth flotation.” During the early 20th century, it dramatically revoluti
