Abstract
Aimed at the characteristics of low grade, high oxidation rate, good floatability and easy agilitization, through experiment research,the technological flowsheet of copper-nickel mixed flotation and copper-nickel separation was adopted. By making full use of the absorption competition, CMC was used in copper-nickel mixed concentration, changing the absorption competition strength of gangue minerals,making the adsorption intensity of the valuable ore increased, improving the floatability of nickels and realizing the separation of the valuable and gangue minerals. After the optimal technological conditions were determined, laboratory closed-circuit test could get the copper concentrate with the Cu grade of 21. 55% and the Cu recovery 64. 65% and the nickel concentrate with the Ni grade of 5.19% and the Ni recovery of 66. 80%.关键词
