Experimental Study on Flotation Process of a Foreign Gold Mine
In order to explore the development and utilization value of a foreign gold mine,based on the study of ore properties,the influence test of grinding fineness,pH regulator,vulcanizing agent,activa-tor,collector and pulp concentration on the separation effect of the gold ore were carried out.The experimen-tal results show that the flotation process of one roughing,one cleaning and four scavenging is adopted,un-der the conditions of grinding fineness of-0.074 mm 85%,vulcanizing agent sodium sulfide dosage of 1 000 g/t,activator copper sulfate dosage of 400 g/t,combined collector butyl xanthate + ammonium dibutyl dithio-phosphate dosage of(90 + 60)g/t,2#oil dosage of 40 g/t and pulp concentration of 35%,the gold concen-trate with gold grade of 44.43 g/t and gold recovery rate of 85.58%can be obtained,and the gold grade of tailings is 0.47 g/t.The flotation gold concentrate product index meets the expected technical indicators,which can provide technical basis for the development of foreign the gold resources.
