针对某金矿以自然金存在、且嵌布粒度粗细不均匀的矿石性质,采用重-浮联合工艺回收金.先用摇床重选获得粗粒金,再用浮选回收细粒金.对原矿A u品位为5.37 g/t的矿石,可获得金精矿品位100.21 g/t、回收率97.88%的较好指标.
針對某金礦以自然金存在、且嵌佈粒度粗細不均勻的礦石性質,採用重-浮聯閤工藝迴收金.先用搖床重選穫得粗粒金,再用浮選迴收細粒金.對原礦A u品位為5.37 g/t的礦石,可穫得金精礦品位100.21 g/t、迴收率97.88%的較好指標.

In view of a gold ore containing natural gold with dissemination size with non‐uniform distribu‐tion ,a joint process of gravity separation and flotation was employed for recovering gold .The coarse gold particles were obtained with gravity separation ,and then the fine gold particles were obtained with flota‐tion .When the grades of the crude ore were Au 5 .37 g/t ,very good technical indexes such as gold concen‐trate grade Au 100 .21 g/t ,recovery 97 .88% were obtained .
