| Abstract: | Experimental study was carried out on flotation of a gold ore. In the test, raw ore was milled to a grinding fineness of -0.074 mm 97.52%, sodium carbonate, sodium silicate and copper sulfate were taken as regulators, while 2# oil and ammonium dibutyl dithiophosphate were used respectively as frother and collector. A closed-circuit flowsheet consisting of one stage of roughing, two stages of scavenging and two stages of cleaning resulted in a 94.89% recovery into the concentrate grading 27.50 g/t Au with a yield of 9.20%, while the content of gold in the tailings reduced to 0.15 g/t. |
