  • Patent number: 11007538
    Abstract: Methods of enhancing recovery of value sulfide and/or precious metal-bearing minerals from an ore containing such minerals as well as Mg-silicate, slime forming minerals, and/or clay by adding a froth phase modifier agent to the ore, and subjecting the ore to a froth flotation process performed under acidic conditions, are provided herein.

  • Patent number: 10478829
    Abstract: Collector compositions C for mineral flotation, which include at least one of a hydroxamic acid A, and/or a salt S of a hydroxamic acid A solubilized in a water-soluble organic solvent L, and processes for using same for recovering sulfide and/or oxide minerals in mineral flotation processes are provided herewith.

  • Publication number: 20190111442
    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.

  • Patent number: 10130956
    Abstract: Methods of enhancing recovery of value sulfide and/or precious-metal minerals from an ore containing said minerals and a Mg-silicate, slime forming mineral, and/or clay, and which is subjected to a froth flotation process, by adding to one or more stage of the froth flotation process a froth phase modifier having a polymer containing one or more functional groups, and optionally a monovalent ion modifier enhancing agent, thereby enhancing recovery of a value sulfide mineral and/or a precious metal-bearing mineral.
