Separation process of iron ore,iron ore magnetic

2020-9-8  Most of the iron minerals in a single magnetite ore are because of its simple composition, strong magnetism, easy grinding and easy separation, the weak magnetic separation method is often used. When the grinding particle size is greater than 0.2mm, most iron ore magnetic separation plants usually use one stage grinding-magnetic separation;

Developments in chemical separation of iron ore

2015-1-1  Often, a chemical separation is the only method able to remove phosphorus from iron ores. Phosphorus can occur as phosphorus-containing minerals (e.g., apatite) and being finely dispersed in hematite in oolitic ironstones or in goethite in goethite–hematite banded iron formation ores.
