摘要

The process of plotau00e7u00e3o contu00ecnua to sulfretos containing iron in ores and apparatus for condition continuously these sulphides.Are a process and apparatus for continuous flotation to sulphides containing iron in ores and ore concentrates.The process includes adjusting the pH of an aqueous pulp of the ore or concentrates of minerals to be in the range of 6.5 - 8.5, and after that,The addition of a reducing agent to modify a film of iron hydroxide on the surface of sulphide ore containing iron in ores or ore concentrates to enable the adsorption ofA collector in sulphide ore containing iron. The process also includes adding the collector to the pulp before, during, or after addition of the reducing agent.The process also includes some air in the pulp to increase the potential of the pulp to a level sufficient to allow the adsorption of collector in the sulphides containing iron and then bubbling gas atRavu00e9s pulp and subjecting the aqueous pulp to froth flotation to produce a foam that contains these minerals containing sulphide.
