| Abstract: | Based on the embedding characteristics of macro fine sulfur-containing particles in gold ores and set reagent system,contrast tests were conducted among middling recycling circuit,raw ore rough grinding-twice roughing circuit,raw ore rough grinding-middling regrinding circuit.Compared to the other two circuits,raw ore rough grinding-twice roughing circuit showed better results,obtaining a closed-circuit test index with the concentrate grade being 32.05 g/t and the recovery rate 80.40 % |
