一种离心选矿和浮选相结合的钨、锡回收选矿方法
摘要：
本发明公开了一种离心选矿和浮选相结合的钨、锡金属回收选矿方法，属于钨或锡矿选矿技术领域；采用高速离心选矿机重选和浮选相结合的方法从含钨、锡矿中回收和富集钨、锡资源，根据入选矿石性质和特点，经过一定预处理或不处理，进入高速离心选矿机进行重选粗选，富集得到钨、锡粗精矿，并抛除大量尾矿，钨、锡粗精矿再经浮选分离除杂，得到高品位的钨、锡精矿；本方法具有工艺针对性强、资源化效率高、经济效益明显等优点。
摘要（英）：

The invention discloses a tungsten and tin metal recovery concentration method combining centrifugal concentration with floatation, belonging to the technical field of tungsten or tin ore concentration. The method comprises the following steps of: recovering and enriching tungsten and tin resources from tungsten and tin ores by using a high-speed centrifugal concentrator with a method combining gravity concentration and floatation; performing certain pretreatment or not performing treatment according to the property and characteristic of a milling ore; entering the high-speed centrifugal concentrator for rough gravity concentration; enriching to obtain tungsten and tin rough ore concentrates; removing a large quantity of tailings; and removing impurities from the tungsten and tin rough ore concentrates by performing floatation separation to obtain high-grade tungsten and tin ore concentrates. The method has the advantages of high process specificity, high resource efficiency, remarkable economic benefit and the like.
