Method for recycling copper from brittle-sulfur lead-antimony mineral waste liquid

The invention discloses a method for recycling copper from brittle-sulfur lead-antimony mineral waste liquid. The method comprises the following steps: 1, filtration and concentration: leading waste liquid into a concentration and evaporation tank through a filter screen, and heating the waste liquid to be evaporated and stopping heating the waste liquid to obtain a concentrated solution and thenperforming cooling; 2, adsorptive separation: importing the concentrated solution into a first reaction kettle, adding an adsorbent and performing stirring and adsorption, then performing standing andsettlement, and extracting an upper layer of clearing liquid to obtain copper-rich mud; 3, cleaning and desorption: spraying a desorbent into the copper-rich mud and performing standing to obtain anupper layer of copper-rich solution and putting the copper-rich solution into a second reaction kettle; 4, precipitation and filtration: introducing hydrogen sulfide gas into the copper-rich solutionfrom a gas inlet, stopping i
