Electromagnetic Separation of Copper Iron Sulphides

Feb 09, 2018 Electromagnetic Separation of Galena. Chalcopyrite, sp. gr. 4.15 to 4.3, is too feebly magnetic to be separated raw, and must be roasted to either the magnetic sulphide or the magnetic oxide, these changes taking place in a manner similar to the behavior of pyrite. A one-minute roast at a red heat is sufficient to impart magnetism to ...

Investigation of Efficiency of Magnetic Separation Methods

May 15, 2019 In this research, the efficiency of magnetic separation methods for processing of a low-grade iron pigments ore red ochre has been studied. Based on the mineralogical analyses XRD, thin section and polish studies, the reserve is an iron sedimentary deposit with an average Fe grade of 31.3. The most valuable minerals are Hematite and Goethite and main gangue minerals are Calcite

Investigation of Efficiency of Magnetic Separation Methods

Oct 04, 2018 Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic

Dry Magnetic Separation of Iron Ore of the Bakchar Deposit

Jan 01, 2015 An implementation of two-step concentration afterpurification allowed increasing the iron content in the concentrate up to 48.2. It forces to upgrade the process of dry magnetic separation or carry it out in the liquid phase so-called, wet separation. Fig. 5 shows the iron ore after the process of magnetic separation.

Proceedings Extraction of Iron from Russian Red Mud by

Jan 01, 2015 The main task of magnetic separation is to increase the total iron content in concentrates to a value which allows its further metallurgical processing. Ferruginous ore particles have a rounded shape that facilitates a separation process.

The -values reflect the improvement in color obtained by magnetic separation. EXAMPLE 2. In this Example the required product is retained by magnetic separation while the non-magnetic impurities are washed out. 1000 ml of a washed iron oxide black sludge --Fe 3 O 4-- 50 gl are passed through the laboratory apparatus illustrated in FIG. 2 in 5 minutes.

In this work, separation of aluminium from a high-aluminium lateritic iron ore was achieved by the process of direct reduction with sodium sulfate-magnetic separation, with a powdered direct ...

Reduction roast and magnetic separation of oxidized iron

Jun 01, 1998 The principle of the process consists of converting the iron bearing minerals into the magnetic state so that magnetic separation can be employed to concentrate iron from the ore . The gas used for reduction purposes may be either pure hydrogen, carbon monoxide or industrial gases like blast furnace gas, coke oven gas and producer gas.
