Abstract: In the light of the fine-grained and disseminated gold ore property, the gold mineral from the ore is recovered by flotation with our high efficient T₁₀₁ as dispersant and D₃ as collector.Under the fully dispersing pulp and improving gold collector conditions, when the crude ore contains gold 4.14 g/t, the technical indexes such as the grade of gold concentrate 41.76 g/t and the recovery 89.21% are obtained by one time roughing, one time scavenging and the rougher concentrate two times cleaning after secondary grinding.The research provides scientific technique support for effective use of gold ore.
