Abstract
206,509. Gredt, P. Nov. 4, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Treating ores to facilitate concentration and to remove undesired constituents.-Oolitic, marly or like iron ores are preliminarily treated by crushing or grinding so as to liberate the grains of iron ore from the gangue, followed by wet or magnetic separation. In an alternative method, the ores may be heated so as to calcine the calcareous gangue, and the product slaked; the calcined and slaked material may be subjected to friction, after which part of the gangue is removed by blastsifting or otherwise.
