elution were performed to optimize the elution condition and evaluate the practical application prospect. Batch experimental results showed that the best IE-A elution eciency could be achieved at the K:Mg molar ratio of 8:2, the liquid–solid ratio of 26:1, and the concentration of 0.1 mol/L at the natural solution pH.

Paste Thickeners
Paste/thickened tailings is characterized by the presence of a yield stress, which is the force required to initiate flow. The underflow of high-rate thickeners is "slurry," which has relatively no or only minor yield stress. Conversely, WesTech paste thickeners operate in higher solids concentrations within a yield stress range.

Efficient removal of the residual ammonium from weathered crust elution
To determine the effects of eluent composition on the elimination of the residual ammonium, elution experiments were conducted by using NO 3 –, Cl-, and SO 4 2-as the anions and K +, Mg 2+, and Na + as the metal ions. Fig. 1 shows the residual ammonium elution by different unitary eluents. It was observed that the amounts of …
