Abstract: Methods and systems for the flotation recovery of value materials from sulfide mineral sources are disclosed. The flotation recovery of the value materials is performed in a fluidized bed flotation cell utilizing collector materials that include at least one hydrocarbyl group and at least one functional group including sulfur on the hydrocarbyl group, and the hydrocarbyl group includes 2 or more aliphatic carbons and 6 or more total carbons. The methods and systems of the present disclosure advantageously allow for improved recovery of coarse-sized particles, which reduces time and energy expending during sample grinding stages. The methods and systems of the present disclosure also do not exhibit the detrimental frothing behaviors which can be associated with long-chain collectors typically having 6 or more carbon atoms. The systems and methods can be incorporated into existing processing systems to treat samples before or after conventional processing stages.
