The effect of selective adsorption of dissolved aegirite …

 · Among these iron ores, silicate-type ores, especially the iron-containing-silicate-type iron ores are the most difficult to separate,,,, . Due to the existence of element Fe in iron-containing silicates, similar magnetic property and floatability can be found between iron-containing silicates and iron ores, which causes low flotation separation efficiency with ordinary reagents.
