Gravity Separation: Highly Effective Tool for Gold-Bearing ...

Nov 18, 2021  Abstract The gold recovery from secondary resources is in the spotlight due to its high economic value and as the circular economy’s main objective. As a valuable secondary source, the slag resulted from the gold-bearing electrolytic mud smelting contains up to 0.8–15 k g t−1 Au and 9–13 kg t−1 Ag, respectively. The gravity separation’s use to concentrate gold contained by the slag ...

Heavy Liquid Testing Procedure

Feb 13, 2021  Table 11 also shows a comparable three-stage HLS circuit using two pumps, one between each separation stage. The 92 percent concentrate and 1 percent tailings indicated an excellent separation, but the 55 percent spodumene middlings would require further testing to determine its influence when continuously recycled within the circuit.
