一、前言分解钨矿有多种方法。通常认为高温加压是强化过程的有效途径,特别是对于含锡较高的钨锡中矿及其他中低品位难处理钨矿更是如此。传统方法对钨矿品位有较高要求。就钨锡中矿而言,无论采用苛性钠浸出还是采用盐酸分解,均不能在浸出过程中有效地分离钨锡,而苏打加压浸出
First, the preface There are many ways to decompose tungsten ore. It is generally believed that high temperature pressurization is an effective way to strengthen the process, especially for tungsten-tin ores with high tin content and other moderate-to-low-grade refractory tungsten ores. The traditional method has higher requirements for tungsten ore grade. In the case of tungsten-tin ore, both caustic soda leaching and hydrochloric acid decomposition can not effectively separate tungsten and tin during leaching, whereas soda pressure leaching
