ABSTRACT:
Lanolin is employed as a modifier for froth flotation utilizing conventional collectors such as fatty acids, kerosene, and the like. Lanolin added to the system acts as a depressant which assists in the selectivity of the process for the desired mineral or inhibits the flotation of gangue materials. Scheelite ore flotation is substantially improved using lanolin in addition to a conventional collector such as tall oil.
