Research on Efficient Utilization of Sulphur Concentrate with Deep Flotation Method


Article Preview

A technology of “depth cleaning- sulfuric and acid producing- residuals for ironmaking” is proposed for efficient utilization of sulphur concentration with high quality. The effect of the main factors involving grinding fineness, activators, collector type and dosage was investigated. On this regard, a close-circuit flotation test scheme was proceeded, by which a high quality sulphur concentrate was obtained with 52.39% of iron grade, 86.44% of iron recovery, 39.46% of sulphur grade and 91.52% of recovery sulphur. This concentrate can be directly used in the production of sulfuric acid and preparation of iron concentrate. This technology can be used to fully utilize sulphur and produce high quality concentrate as iron-bearing feed for steel industry, which will help to extend raw material sourcing for Chinese steel industry.
