T/CAPS 088-2026 The technical specifications for extracting valuable metal iron using pure hydrogen reduction of aluminum oxide residue extraction method
Basic Information
Scope
This document specifies the raw material requirements, process principles and procedures, technical requirements, safety and environmental protection, operation and maintenance for extracting valuable metal iron from alumina red mud (hereinafter referred to as "red mud") using the pure hydrogen reduction method. This document is applicable to the process design, equipment selection, production operation and control of extracting metal iron products by treating red mud generated during the production of alumina by the Bayer process, sintering process and combined process with pure hydrogen (H2 volume fraction ≥99%) as the sole reducing agent. This document specifies the raw material requirements, process principles and procedures, technical requirements, safety and environmental protection, operation and maintenance for extracting valuable metal iron from alumina red mud (hereinafter referred to as "red mud") using the pure hydrogen reduction method.
