156 CONDITIONING OF THE ORE IN THE COMMINUTION STEP AND RECOVERY OF DESIRED METAL VALUES BY FLOTATION PCT/IB2013061277 2013-12-23 WO2014097273A4 2014-09-18 AMOS STEPHEN RALPH; NAKAMURA IICHI; LASCELLES DOMINIQUE
The invention provides method to recover, by means of froth flotation, a desired metal value from a feedstock containing it. In a comminution step, the feedstock is comminuted using comminuting media of an iron and chrome steel alloy comprising from 12% to 30% chrome. In a conditioning step, the feedstock material is contacted with thiourea and/or oxalic acid as primary flotation reagents. The conditioning step comprises the comminution step, in which a quantity of the primary flotation reagent/s being added and preconditioned comminuted feedstock material being obtained. The conditioning step also comprises an optional conditioning finishing step, in which a mixture of the preconditioned comminuted feedstock material and a liquid is subjected to stirring and with conditioned comminuted feedstock material being obtained from the finishing step. In a recovery step, at least some of the desired metal value is recovered by froth flotation from the preconditioned or conditioned feedstock.
157 FLOTATION REAGENTS AND FLOTATION PROCESSES UTILIZING SAME PCT/US2009050784 2009-07-16 WO2010011552A2 2010-01-28 CHEN HAUNN-LIN TONY; BHAMBHANI TARUN; VASUDEVAN MUKUND; DEO PUSPENDU; NAGARAJ DEVARAYASAMUDRAM RAMACHANDRAN
Methods of enhancing recovery of value sulfide or precious minerals from an ore containing Mg-silicate, slime forming minerals, and/or clay by crushing the ore, grinding the ore, and subjecting the ground ore to a flotation process, in conjunction with the addition of at least one monovalent ion modifier enhancing agent and/or froth phase modifier agent to the ore, are provided herein.

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.
159 Foam Prevention In The Reverse Flotation Process For Purifying Calcium Carbonate US15923236 2018-03-16 US20180200731A1 2018-07-19 Stefan DILSKY; Wagner Claudio DA SILVA; Monica SPECK CASSOLA; Nilson Mar BARTALINI; Zaira Guimaraes DUARTE; Jorge Antonio ARIAS MEDINA; Antonio Pedro OLIVEIRA FILHO
This invention relates to an composition, comprising A) at least one quaternary ammonium compound which is a collector for the reverse flotation of magnesium minerals from calcium carbonate B) at least one antifoam agent C) a solvent and its use in the reverse flotation of calcium carbonate.
160 SULFONATED MODIFIERS FOR FROTH FLOTATION US15686757 2017-08-25 US20180057679A1 2018-03-01 Jianjun Liu; Kevin O'Brien; Daniel N.T. Hay
Improved sparge compositions for reverse froth flotation separation and uses thereof, and methods of reverse froth flotation are described. The sparge compositions comprise sulfonated polymeric modifiers which can act as dispersants and depressants, and the compositions are suitably used in the reverse froth flotation of particulate material containing ultrafine particles. For example, the compositions and methods can be used in the separation of iron oxide beneficiary from iron ores comprising silica, silicates, and the like.
