The invention discloses a composite adsorbent which can realize efficient adsorption of thallium ions separated from slag through efficient thallium ion adsorption sites generated in a physical and chemical dual combination form with an Fe-Mn compound by taking active silicate as a matrix. Meanwhile, a synchronous separation mode is adopted, nickel in the slag is separated and regenerated in the form of nickel hydroxide, and full-chain integrated application of the resource thallium-containing nickel slag from recovery to production of a new product is achieved. 本申请公开了一种复合吸附剂，该产品通过以活性硅酸盐作为基体与Fe-Mn复合物经物理和化学的双重结合形式产生的高效铊离子吸附位点，可实现对矿渣分离出的铊离子的高效吸附；同时，本申请还采用同步分离的方式，将矿渣中的镍以氢氧化镍的形式分离再生，实现资源含铊镍矿渣的从回收到产出新产品的全链条一体化应用。
