    We claim 1. A process for enriching a mineral from a silicate containing ore by carrying out a froth flotation in the presence of polyester polyammonium based compound collecting or co collecting agent and a froth modifier, wherein said froth modifier is selected from the group consisting of at least one of the compounds of general formula I or mixtures thereof wherein X is C1 C3 alkyl R is.Finally, the concentrate is obtained, and the whole froth flotation is done. The ore particles in the slurry contact and collide with the froths, and those ore particles with good floatability selectively adhere to the froths and are carried up into the mineralized foam layer (compose of gas liquid solid three phases).

  • Froth Flotation Of Mixed Feldspar

    Jul 23, 2014 Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water). Since its discovery, froth flotation has been a major component for the processing of sulfide rich.Nov 04, 2016 The froth free flotation vessel comes by way of Eriez Flotation Division, which patented it in 2002 and marketed it under the name HydroFloat.
