Abstract
The invention discloses a composite collecting agent which comprises an organic carboxylic acid organic matter and a xanthate medicament in a mass ratio of (6-8): (2-4). The invention also discloses application of the composite collecting agent in chalcopyrite flotation, which comprises the following steps: crushing and grinding chalcopyrite, adding the composite collecting agent and an inhibitorinto ore pulp under the conditions of proper ore pulp concentration, fineness and pH, stirring, adding a foaming agent, and carrying out flotation. When the composite collecting agent is applied to mineral separation of chalcopyrite and gangue, oxygen in phosphonic acid (phosphonyl) and carboxylic acid (carboxylate) functional groups in organic carboxylic acid organic matters of a main agent can be selectively combined with copper and iron sites on the surface of the chalcopyrite, so that selective separation of the chalcopyrite and the gangue is realized; and the strong collecting property ofthe auxiliary agent xanthate can strengthen recovery of the chalcopyrite and improve foam merging, the synergistic effect of the two agents greatly improves the grade and the recovery rate of copperconcentrate, and the effect is superior to that of a traditional xanthate collecting agent.
