Abstract
The effects of mineral pretreatment, ionic strength, pretreatment temperature, and cationic collector type on the flotation characteristics of quartz and magnetite were investigated. The extent of crushing prior to pretreatment had a significant influence on quartz flotation recovery from approximately pH 2 to pH 8. Alkyl amine collector chain length and the presence of one or two functional amino groups were critical parameters related to ionic strength. Increasing the pretreatment temperature had a slight depressing effect on quartz and magnetite flotation recoveries. In most cases, n-dodecyl-1, 3-diaminopropane was a superior flotation collector to n-dodecylamine for the recovery of quartz and magnetite.
