The invention discloses a valuable metal collaborative recovery method for waste circuit boards and tin removal waste liquid. The method includes the steps of soaking the waste circuit boards in the tin removal waste liquid at normal temperature and under normal pressure; and after the soaking is completed, taking out the circuit boards and removed components, and carrying out fractional precipitation recovery of valuable metals in leachate at the normal temperature and under the normal pressure. The sequence of precipitation is as follows: adding sodium hydroxide to precipitate tin, wherein the pH value is 0.5-2.5, and adding sulfuric acid to precipitate lead, wherein the mole ratio of SO4 <2-> to Pb <2+> is greater than 1.4; adding the sodium hydroxide to precipitate iron, wherein the pH value is 2.5-4.0; adding the sodium hydroxide to precipitate copper, wherein the pH value is 4.5-6.5; and adding the sodium hydroxide to precipitate zinc, wherein the pH value is 6.5-8.5. According to the valuable metal collaborative recovery method for the waste circuit boards and the tin removal waste liquid, the whole process is carried out at the normal temperature and under the normal pressure so that release of heavy metals such as the lead to the atmosphere can be reduced; the technological process is simple, and metals such as tin and copper in the waste circuit boards can be collaboratively treated on the premise that the original treatment process of the tin removal waste liquid is not changed; and the valuable metals in the waste circuit boards and the tin removal waste liquid can be comprehensively recovered.
