| Abstract: | Experimental research has been carried out on the dressing of one highly carbonaceous refractory gold ore from Luonan County according to its properties.The results show that the flotation-railings roasting-water extraction-cyanidation leaching flow sheet can obtain good test index;the closed circuit of flotation obtains gold grade 42.14 g/t and recovery rate 61.88 % for crude concentrate,and gold grade 16.26 g/t and recovery rate 11.49 % for concentrate;the leaching rate of tailings cyanidation is 75.68 % and total gold recovery rate reaches 93.52 %. |
