Method for comprehensively recovering gold, silver and iron from gold extraction waste residues through collaborative roasting of pyrite
The invention belongs to the technical field of comprehensive utilization of metallurgical tailing resources, and relates to a method for comprehensively recovering gold, silver and iron from gold extraction waste residues through collaborative roasting of pyrite. 2) low-temperature reduction roasting; 3) flotation and enrichment of gold, silver and copper; and 4) performing high-temperature reduction roasting to magnetically separate iron. According to the characteristics of low-gold pyrite and cyaniding gold extraction waste residues, the thought of'roasting waste treatment, gold and silver gradient recovery and comprehensive recovery of iron 'of a multi-stage treatment process is adopted, and a material fine grinding gold extraction treatment technology, a low-temperature reduction roasting technology, a gold, silver and copper flotation enrichment technology and a high-temperature reduction roasting iron magnetic separation technology are mainly adopted; the gold mine cyanide-containing waste residues are synergistically subjected to deep treatment, roasting of the low-gold pyrite and purification treatment of the gold extraction residues are combined, and comprehensive recovery of gold, silver and iron in the pyrite and the cyanide waste residues is achieved. The method is good in treatment effect, high in efficiency, stable in system operation, simple in technological process and convenient to realize industrial application.
本发明属于冶金尾矿资源综合利用技术领域，涉及一种硫铁矿协同焙烧处理提金废渣综合回收金银铁的方法，包括如下步骤：1)配料细磨提金处理；2)低温还原焙烧；3)浮选富集金银铜；4)高温还原焙烧磁选铁。本发明根据低金硫铁矿以及氰化提金废渣的特点，采用多级处理工艺“焙烧治废、金银梯级回收、综合回收铁”的思路，主要采用配料细磨提金处理技术、低温还原焙烧技术、浮选富集金银铜技术、高温还原焙烧磁选铁技术，协同对黄金矿山含氰废渣进行深度处理，将低金硫铁矿焙烧与提金渣净化治理相互结合，并实现硫铁矿及氰化废渣中金、银、铁的综合回收；处理效果好、效率高，系统运行稳定，工艺流程简单，便于实现工业应用。
