【摘要】：蒙古某銅礦含銅0.61%,含硫2.57%,含金0.80g/t,含銀15.12g/t,礦石中銅礦物主要為黃銅礦、斑銅礦及輝銅礦,脈石礦物有石英、長石、云母等。礦石中金、銀等有價元素與黃銅礦、黃鐵礦等金屬礦物之間嵌布關(guān)系密切。本文研究針對該礦石特征,采用銅優(yōu)先-銅和脈石浮選分離工藝流程,粗選采用選擇性捕收劑BKH優(yōu)先選銅,精選采用新型抑制劑BKL抑制脈石礦物,最終獲得實驗室閉路試驗結(jié)果為:銅精礦含銅24.85%,銅回收率81.88%;含金21.87g/t,金回收率55.00%;含銀515.80g/t,銀回收率68.89%。
[Abstract]:A certain copper mine in Mongolia contains 0.61 copper, 2.57 sulfur, 0.80 g / t of gold and 15.12 g / t of silver. The main copper minerals in the ore are chalcopyrite, porphyrite and chalcopyrite, and gangue minerals are quartz, feldspar, mica, etc. Gold, silver and other valuable elements are closely related to the distribution of chalcopyrite, pyrite and other metal minerals. In this paper, according to the characteristics of the ore, copper preference-copper and gangue flotation separation process was adopted, the selective collector BKH was used for coarse separation of copper, and a new depressant BKL was used to suppress gangue minerals. The results of laboratory closed circuit test are as follows: copper concentrate contains 24.85 copper, copper recovery is 81.88; gold is 21.87 g / t, gold recovery is 55.00; silver is 515.80 g / t, silver recovery is 68.89.
