Title:
METHOD FOR REDUCING OXIDE ORES BY USING SQUARE CARBONIZATION CHAMBER OF COKING PLANT
Document Type and Number:
WIPO Patent Application WO/2020/216320
Kind Code:
A1
Abstract:
A method for reducing oxide ores by using a square carbonization chamber of a coking plant, comprising performing mixing; pressing ores into spheres by means of a ball pressing machine, and putting same into the square carbonization chamber from the top to perform reduction reaction, or directly pulverizing block-shaped oxides into regular small blocks and mixing same with a carbonaceous reductant before being put into the square carbonization chamber from the top to perform reduction reaction, or pressing the oxides into the shapes of honeycomb briquettes having holes and then pushing same into the square carbonization chamber from a side surface by means of a tray to perform reduction reaction, so as to well adapt to reduction reaction of oxide ores in different forms, and generate a simple-substance metal material.
