Inspired by the documentary motto of the CPC Central Committee [1974] No.21, under the sponsorship of the great people’s pro-Lin Kong-kung movement, in July 1974, at the Tan-ping mining station in Dongchuan Mining Bureau, C_ (5- 9) and C_ (7-9) sodium alkyl hydroxamate (hereinafter referred to as sodium hydroxoate) flotation Dongfengling copper oxide ore industrial test. 4580 tons of ore were co-processed with the new agents during the trial. The results of industrial tests show that sodium hydroxamate is a very effective flotation catch for the Dongfengling copper oxide ore, which is rich in all kinds of copper arsenate minerals Agent. Mixed add sodium hydroxamate, butyl xanthate results, the election plant
