Froth flotation

A method of selectively recovering an arsenopyrite, pyrrhotite or like mineral from a material containing such a mineral and pyrite which includes the steps of providing a slurry of the material, adding a dialkyl (C3-8)-dithiophosphate to the slurry, passing a gas through the slurry to cause the min...

Beschreibung
Zusammenfassung:	A method of selectively recovering an arsenopyrite, pyrrhotite or like mineral from a material containing such a mineral and pyrite which includes the steps of providing a slurry of the material, adding a dialkyl (C3-8)-dithiophosphate to the slurry, passing a gas through the slurry to cause the mineral to be carried to the surface of the slurry and report in a first float concentrate, removing this concentrate from the slurry, activating the mineral remaining in the slurry by adding a suitable water-soluble copper salt to the slurry, adding a monoalkyl (C3-10)-dithiocarbamate to the slurry, passing a gas through the slurry to cause mineral to be carried to the surface of the slurry and form a second float concentrate, removing the second concentrate from the slurry and combining the first and the second float concentrates. UN METODO PARA RECUPERAR SELECTIVAMENTE UNA ARSENOPIRITA, PIRROTINA O MINERAL SIMILAR DE UN MATERIAL QUE CONTIENE DICHO MINERAL Y PIRITA, CUYO METODO CONSISTE EN FORMAR UNA SUSPENSION DEL MATERIAL, AGREGAR A LA MISMA UN DIALQUIL (C3C8) DITIOFOSFATO, PASAR UN GAS POR LA SUSPENSION PARA QUE EL MINERAL SEA ARRASTRADO A LA SUPERFICIE DE LA MISMA Y FORME UN PRIMER CONCENTRADO DE FLOTACION, SEPARAR ESTE CONCENTRADO DE LA SUSPENSION, ACTIVAR EL MINERAL QUE QUEDA EN LA SUSPENSION POR ADICION DE UNA SAL DE COBRE SOLUBLE EN AGUA ADECUADA, AGREGAR UN MONOALQUIL (C3-10) DITIOCARBAMATO A LA SUSPENSION, PASAR UN GAS POR LA SUSPENSION PARA QUE EL MINERAL SEA ARRASTRADO A LA SUPERFICIE Y FORME UN SEGUNDO CONCENTRADO DE FLOTACION, SEPARAR EL SEGUNDO CONCENTRADO DE LA SUSPENSION Y COMBINAR EL PRIMERO Y SEGUNDO CONCENTRADOS DE FLOTACION.
