Abstract
一种含金硫氧混合锑矿的回收方法，首先将矿石磨矿至矿物单体解离后，采用六偏磷酸钠作分散剂，水玻璃作硅、钙质脉石抑制剂，硫化钠作硫化剂、硫酸铜作锑、金矿物活化剂，异戊基黄药作捕收剂，2号油作起泡剂对含金硫氧混合锑矿进行浮选得锑金混合精矿。
Description
技术领域
本发明涉及一种含金硫氧混合锑矿的回收方法，特别是对于锑氧化率高、金品位低且硅、钙质脉石矿物较多的锑、金混合矿，需通过多种流程组合才能回收的低品位含金硫氧混合锑矿。
背景技术
国内外一些含金硫化矿床中，常常伴生有如硫化锑、氧化锑等对金冶炼有害的有色金属矿物，这些伴生矿物原矿品位低，往往在金的回收过程中一般不考虑单独回收，其原因在于伴生锑品位低，单独回收的价值不大，同时，由于锑氧化率高，部分氧化锑矿物难浮选，一般采用多种流程组合对基进行回收。为了提高锑金的回收率，在浮选过程中往往添加过量药剂，这样不可避免地将硫化锑及一部分微细粒的硅、钙质脉石矿物浮选得到含锑的混合金精矿，但氧化锑回收却不尽如意，如能将这部分氧化锑也回收，不仅降低了企业回收金的成本，同时也能对资源的综合回收。
发明内容
本发明的目的在于提供含金硫氧混合锑矿的回收方法，特别是对于锑氧化率高、金品位低且硅、钙质脉石矿物较多的锑、金混合矿，需通过多种流程组合才能回收的低品位含金硫氧混合锑矿。
本发明采用以下技术方案达到上述目的：一种含金硫氧混合锑矿的回收方法，首先将矿石磨矿至矿物单体解离后，采用六偏磷酸钠作分散剂，水玻璃作硅、钙质脉石抑制剂，硫化钠作硫化剂、硫酸铜作锑、金矿物活化剂，异戊基黄药作捕收剂，2号油作起泡剂对含金硫氧混合锑矿进行浮选得锑金混合精矿。
药剂总用量为：六偏磷酸钠50～80g/t，水玻璃500～600g/t，硫酸铜800～1000g/t，硫酸铜80～100g/t，异戊基黄药300～350g/t，2号油30～50g/t。
本发明的突出优点在于：
1、工艺流程简单，只需一次粗选三次扫选两次精选就可得合格的混合锑金精矿。
2、采用无毒价廉，对硫氧锑矿有选择性抑制的药剂，较好地解决了硫氧混合锑矿的浮选回收问题。
