Abstract
The present invention relates to processes including the step of electrochemically treating an iron mineral. The processes are for improving the grade of iron, producing a magnetic iron mineral, or producing an iron oxide. In one aspect, the process for improving the grade of iron includes electrochemically treating a slurry including at least one iron mineral to thereby improve the grade of the iron in the slurry.
Claims20
A process for improving the grade of iron, the process comprising electrochemically treating a slurry comprising at least one iron mineral to thereby improve the grade of the iron in the slurry, wherein electrochemically treating a slurry comprises electrochemically treating at least one solid non-magnetic iron mineral to thereby produce a magnetic iron mineral, and wherein the electrochemical treatment is performed in the presence of a carboxylic acid.
A process for improving the grade of iron, the process comprising electrochemically treating a slurry comprising at least one iron mineral to thereby improve the grade of the iron in the slurry, wherein the step of electrochemically treating a slurry comprises electrochemically treating at least one iron hydroxide and/or at least one iron oxide hydroxide to thereby produce at least one iron oxide, wherein the at least one iron hydroxide and/or the at least one iron oxide hydroxide is a solid, and wherein the electrochemical treatment is performed in the presence of a carboxylic acid.
