厄瓜多尔某铜尾矿浆絮凝沉降优选絮凝剂试验

为提高厄瓜多尔某铜矿浓密机的处理效率，降低输送成本，减少跑浑现象，进行了尾矿

絮凝沉降试验。结果表明：矿浆浓度 16.67%、絮凝剂用量 20 g/t时，添加絮凝剂 BK816F，尾矿浆沉降

速度最快，沉降80 s后清水层高度即可达15 cm；矿浆浓度30%时，随着絮凝剂添加量的增大，尾矿浆

沉降速度总体加快，其中BK816F效果最明显，可在较低用量、较短时间内达到较好的沉降效果；质量

浓度同为0.1%的絮凝剂溶液，BK816F的黏度最低。各项性能指标均表明，BK816F可作为该铜矿的

高效絮凝剂。

In order to improve the treatment efficiency of thickener in a copper mine of Ecuador，re⁃

duce the transportation cost and reduce the phenomenon of muddy running，the flocculation sedimentation

test of tailings was carried out. The results show that when the slurry concentration is 16.67%，the flocculant

dosage is 20 g/t，and the flocculant BK816F is added，the sedimentation rate of the tailings slurry is the fast⁃

est，and the height of the clear water layer can reach 15 cm after 80 s of sedimentation. When the slurry con⁃

centration is 30%，the sedimentation rate of tailings slurry is generally accelerated with the increase of floc⁃

culant dosage，and the effect of BK816F is the most obvious，which can achieve better sedimentation effect

in a lower dosage and a shorter time. The viscosity of BK816F is the lowest when the mass concentration of

flocculant solution is all 0.1%. All the performance indexes show that BK816F can be used as an efficient

flocculant for the copper mine.
