解决人造金红石细化的方法
摘要：
本发明属于冶金及化工领域，具体涉及解决人造金红石细化的方法。本发明所要解决的技术问题是现有人造金红石制备工艺采用强搅拌浸出时粒度细化非常严重。本发明解决人造金红石细化的方法包括以下步骤：(1)对钛精矿进行烘干、筛分；(2)将钛精矿在800～850℃下进行低温弱氧化反应；(3)然后在750～800℃下进行弱还原反应；(4)加入盐酸，在加热搅拌条件下浸出；(5)固液分离，经洗涤、烘干得到富钛料成品。本发明能制备出满足沸腾氯化需要的高品质人造金红石产品，工艺流程简单、高效。
摘要（英）：

The invention belongs to the field of metallurgy and chemical industry, and particularly relates to a method for solving artificial rutile refinement. The invention aims to solve the technical problemthat the granularity refinement is very seriously thinned when adopting strong agitation leaching in the existing artificial rutile preparation process. The method for solving artificial rutile refinement comprises the following steps of (1) drying and sieving the titanium concentrate; (2) performing low-temperature weak oxidation reaction on the titanium concentrate at 800-850 DEG C; (3) then performing weak reduction reaction at 750-800 DEG C; (4) adding hydrochloric acid, and leaching under heating and stirring conditions; and (5) performing solid-liquid separation, washing and drying to obtain a titanium-rich material finished product. Through the method disclosed by the invention, the high-quality artificial rutile products meeting the requirements of boiling chlorination can be prepared, and the process flow is simple and efficient.
