中文摘要：
基于H．B流变模型预测谦比希铜矿全尾砂浆重力脱水极限浓度。利用桨式转子流变仪检测不同浓度浆体流变曲线，然后采用H．B模型回归浆体流变参数，最后分析得到流动指数n=1时的浆体浓度为极限浓度。结果表明，流动指数n值随浓度增大而单调减小；浓度为69％、70％左右时，n值最接近1，n=1时的回归浓度为69．11％；全尾砂浆脱水的工业预测值最大约为69％。
英文摘要：
Limiting concentration of full tailings slurry of Chanbishi Copper Mine by gravity dehydration was predicted based on H-B rheological model. Using propeller type rotor rheometer to test slurry rheology curve of different concentration, then adopted H-B model regress slurry rheology parameters, fi- nally obtained slurry concentration is the limiting concentration when flow index n = 1 through analysis. The results indicated, flow index n value monotonically reduced with concentration increasing; when con- eentration was around 69% ,70%, n value was mostly close to when n = 1 ; the maximum industry predictive value of full
