Process for extracting metals from sulfide Minerals concentrates containing applying Direct Reduction with regeneration and recycling of the reducing Agent and the Iron Flux CArbonato sodium

摘要

A procedure for the continuous extraction of metals from sulfide ores containing metals or metals, whether or not accompanied by iron, characterized by direct reduction of metals or metals, Recovery and recycling of reducing iron and sodium carbonate melting agent from the slag and liquid and gas emissions generated by the process, and the following steps are used in the process: extracting metal from the furnace; (a) The components of sodium sulfide in slag were dehydrated and filtered;Regeneration of sodium carbonate in recovery reactor, disposal of sulfurized gas and generation of sulfur, the method of which is to capture and transport gas effluent to solid gas reactor, sintering iron oxide by accumulation and heating after temperature control; Carbon monoxide and hydrogen are produced in the oxidation furnace to reduce gas, and the reducing iron agent is regenerated for recovery by reducing such metals contained in iron oxide.
