Several methods have been reported for the preparation of magnetite, among which the co-precipitation method is the simplest method in which no organic solvents are required [20,21]. In this method, the reaction medium must be basic and the ratio of ferric salts to ferrous should be 2 to 1 [ 18, [22], [23], [24] ].
At Port Orem, New Jersey, the New Jersey Iron Mining Co. is operating a magnetic-concentration plant on magnetite ores. The ore carries magnetite in stringers and grains in a gangue of quartz and some finely disseminated apatite. It is crushed in breakers and rolls to a size varying from 20 mesh to ¼ in., depending upon the ore treated.
