钛铁矿储量十分丰富,但精矿品位仅含TiO_250%左右,需经富集才能达到金红石的品位(含TiO_295%以上).因此,富集钛铁矿的研究已成为近十年来钛工业研究中最广泛的课题之一.本文就当前的生产方法及科研动向进行介绍. 一、生产方法人造金红石的生产方法有多种,已知国内外工业方法有下述几种. The reserves of ilmenite are very rich, but the grade of concentrate contains only TiO 2 about 50%, which needs to be enriched to reach the grade of rutile (including TiO 2 95%) .Therefore, the research on enrichment of ilmenite has become the research of titanium industry in recent ten years One of the most extensive topics.This paper describes the current production methods and research trends.First, the production methods There are many man-made rutile production methods, known domestic and foreign industrial methods are the following.
