china and low grade magnetite ore

Separating the Anshan Type Low Grade Hematite Ore with

According to the nature of the ore which containing hematite and magnetite under the conditions for example ore grade is % the first fineness of grinding 200 mesh is 50% the second fineness of grinding 200 mesh is more than 95% it is concluded that concentrating circuit consisting of first grind Feebleness magnetic separation high intensity magnetic separation second grind second

benefication of low grade iron ore by magnetic separator

china low cost magnetic separation of iron ore The Lower grade sources of iron ore generally require beneficiation using techniques like crushing milling gravity or heavy media separation screening and silica froth flotation to improve the concentration of the ore and remove impurities Low grade iron ore beneficiation process 1

Another ore sample B of % Fe was prepared from ore sample A by removing magnetite using low intensity magnetic separation at H 800 De X ray diffraction analysis showed hematite augite quartz fluorite and carbonates as the main minerals This sample was ground in a steel ball mill to 98% passing 400 mesh In tap
