Industry Background The Chinese standard YS/T 298-2024 “High-Titanium Slag” was officially released on October 24, 2024, and will come into force on May 1, 2025. The revision reflects the latest changes in China’s titanium industry, including shifts in resource availability, advances in production technology, and growing requirements for green and sustainable manufacturing.

1. High-Titanium Slag: A Strategic Resource in the Global Value Chain High-titanium slag is not a byproduct or waste; it is a premium titanium mineral enrichment achieved through sophisticated pyrometallurgical processes. As a high-concentration carrier of Titanium Dioxide (TiO₂), it serves as the essential feedstock for producing Titanium Tetrachloride (TiCl₄), high-end Titanium Dioxide pigments, and the strategic metal—Titanium Sponge. In an era of tightening environmental regulations and increasing resource efficiency, high-titanium slag has become a cornerstone of the global supply chain, offering low emission profiles, high resource utilization, and superior end-product quality.

In the modern industrial ecosystem, High-Titanium Slag (High-Ti Slag) is far more than a mere intermediate product; it serves as a critical bridge connecting raw mineral extraction with high-end precision manufacturing. Produced through the electric furnace smelting of titanium concentrates, high-titanium slag typically features a TiO₂ (Titanium Dioxide) concentration ranging from 74% to 90%. This article provides a professional analysis of the multifaceted roles of high-titanium slag and its indispensable value in resource circulation and technological evolution.
