| 中文摘要: |
| 有色金属矿产资源中伴生的金银矿物是贵金属金银资源的重要来源，伴生金银的回收一直是各国选矿工作者研究的重点。伴生金银资源主要分布在硫化铜、硫化铜铁及硫化铅锌矿石中，由于共伴生金银嵌布粒度粗细不均，金银捕收剂对矿石的适应能力不强，导致现有浮选工艺及药剂制度难以满足伴生金银回收的要求，严重影响了伴生金银的回收效果。在伴生金银工艺矿物学研究基础上，针对不同矿石中伴生金银资源的回收特点，选矿工作者通过改进和强化磨矿工艺、选择合理的工艺流程及开发多种新型金银捕收剂，显著提高了有色金属硫化矿中伴生金银资源的选矿指标。 |
| 英文摘要: |
| The associated gold and silver, mainly distributed in the copper sulfide ore and iron sulfide ore and copper-lead-zinc sulfide ore, are an important source of gold and silver and need to be recovered. The existing flotation technology and reagent regime do not meet the requirements for recovering associated gold and silver efficiently. The collectors used in the flotation can not be applied to the ores due to the uneven grain sizes of gold and silver inlay in these ores. Basing on the process mineralogy research of the associated gold and silver, the mineral processing workers have significantly improved the existing flotation technology by strengthening the grinding process and developing a variety of more effective gold and silver collectors. |
