细粒难选金红石矿粗选抛尾研究进展

Research Progress of Roughing on Fine-grained Refractory Rutile Discard Tailings

我国金红石资源多为原生金红石矿,且大多品位较低,嵌布粒度细,矿石性质复杂,属于难选矿石,选矿成本过高导致大量金红石资源不能得到开发利用。如何有效降低金红石选矿成本以及提高资源的综合利用率是金红石选矿研究的重点。本文综述了我国近年来对细粒难选金红石矿粗选抛尾研究进展,对相关的选矿工艺特点及规律做出了总结,指出了现阶段存在的问题和新的研究方向。

Primary rutile is the main type futile resource in our country. Most of them belong to the low-grade refrac- tory ore with fine particle size distribution and complex ore property. Because of the high cost of mineral processing, a lot of rutile resources can not be utilized. The key is how to reduce the cost of rutile roughing stage and solve the problem of comprehensive utilization. This paper reviewed the recent progress of fine-grained refractory rutile roug- hing, summarized the beneficiation process and pointed out the existing problems and the new research directions.
