The invention discloses a method of enriching valuable metals through collaborative smelting of a gold-antimony deposit and auriferous pyrite cinder. According to the method, in a smelting burdening process of the gold-antimony deposit, auriferous pyrite cinder replaces the original flux iron ore concentrate, the gold-antimony deposit and the auriferous pyrite cinder are subjected to collaborative smelting together, and a given amount of sodium carbonate is added for reducing a melting point of slag and improving the flowability of a melt, so that the smelting temperature is reduced effectively, the valuable metals like gold and silver in the auriferous pyrite cinder and antimony concentrate can be enriched in crude metallic antimony more, and the probability of oxygenation volatilization of antimony is reduced. The method has the outstanding advantages as follows: firstly, one-step smelting allows antimony to generate metallic antimony more, and the scattering problem of antimony in crude metal, flue gas and iron-antimony matte in the traditional technology is solved; secondly, difficult-to-treat solid waste, namely the auriferous pyrite cinder is used comprehensively, the iron ore concentrate is replaced, the consumption of primary resources is reduced and the industrial solid waste is treated collaboratively; finally, the valuable metals, namely gold and silver in the concentrate and the auriferous pyrite cinder are enriched and recovered, the energy consumption is reduced, and the collaborative smelting effects of comprehensive recovery, low carbon cleaning and production process centralization are exerted.
