| Abstract: | To beneficiate a copper oxide ore with low copper grade,high oxidation rate and high combination ratio of inseparable copper,a new reagent system was adopted and systemic flotation tests were carried out.A sulphidizer and ammonium sulfate were introduced in advance correspondingly to sulfurate and activate the ore,thereafter,a combined depressant consisting of sodium silicate and sodium hexametaphosphate was added to strengthen depression and a combined collector consisting of xanthate 680,butylamine dithio... |
