description The invention relates to a beneficiation method of veinlet disseminated low-grade porphyry type copper ore, belonging to the technical field of mineral metallurgy processing. The technical problem tobe solved by the invention is the difficulty of low copper ore grade and various copper minerals in mineral processing. A technology for introducing a copper and associated gold and silver mineral high-efficiency combined collector, adding lime and sodium sulfide for pulp blending in roughing process and introducing sodium silicate and sodium hexametaphosphate in the fine screening process is adopted. The problems that the recovery rate of useful minerals is low, the fine screening process is long and the concentrate grade is not high in beneficiation of the veinlet disseminated low-grade porphyry type copper ore are solved. The recovery of main metal copper and associated gold and silver is effectively increased, the quality of copper concentrate is improved, the stability of beneficiation is improved, the advers
