Development and Industrial Application of New Molybdenum-Bismuth Sulfide Ore Collector CYB-06
Based on the properties of Shizhuyuan molybdenum-bismuth sulfide ore,a new eco-friendly collector CYB-06 was developed.The results of industrial experiment show that,when using collectors CYB-06 and ethyl thiocarbamate coordinately,the recovery of molybdenum,bismuth and sulfur in the bulk sulfide concentrate attains respectively to 84.12%,67.90%and 83.28%,up by 2.32 percentage points,2.82 percentage points and 6.55 percentage points respectively,and the COD in the wastewater from processing plant is 117 mg/L,declined correspondingly by 41.21%,compared to the concentrate obtained with the combined collector of butyl xanthate and ethyl thiocarbamate.As CYB-06,without pungent odor,exhibits good selectivity index,and leads to low COD in the wastewater from processing plant,its application is of significance for improving product quality and operation efficiency,cleaning production and environmental protection of mining enterprises.
