METAL EXTRACTION FROM MINERAL ORE BY DRY METALLURGICAL PROCESS

摘要

The invention relates to a process for obtaining metal values from ores containing such metals as oxides or convertible into such oxides, the process comprises grinding an ore at room temperature; reducing said ground ore with reducing agents to a gaseous mix comprising gangue; condensing the gaseous mix with water, to a metals and gangue solution as a product and inert gases as a second product which are vented to the atmosphere; separating water (which is further recycled) from said metals and gangue solution via sedimentation, filtration and drying to obtain a cake; subjecting said cake to gaseous separation in order to yield the metals mix in gaseous form as product and gangue as a residue; selectively condensing said metals mix into each metal component according to their different condensation temperatures.
