Based　on　the　leaching　solution　of　tungsten　secondary　resource,　the　metal　separation　properties　of　tungsten-　containing　systems　such　as　the　W-Mg-Si-H2O,　the　W-Al-H2O,　the　W-Fe-Mo-H2O　and　the　W-Ca-V-H2O,　were　investigated　by　theoretical　E-pH　diagrams　and　experiments.　The　results　demonstrated　that　the　precipitation　rates　of　Si　and　W　were　99%　and　2.4%　respectively　at　pH　=　9　in　W-Mg-Si-H2O　system;　the　precipitation　rates　of　Al　and　W　were　99.8%　and　3.0%　respectively　at　pH　=　7　in　W-Al-H2O　system;　the　precipitation　rates　of　W　and　Mo　were　95%　and　24%　respectively　at　pH　=　7　in　W-Fe-Mo-H2O　system;　the　precipitation　rates　of　V　and　W　were　91.2%　and　4.3%　respectively　at　pH　=　13　with　Ca:V　=　3:1　in　V-Ca-W-H2O　system.　The　theoretical　predictions　were　in　good　agreement　with　the　experimental　results.　The　metal　separation　for　a　tungsten-containing　polymetallic　solution　of　W,　Mo,　V,　Si　and　Al,　was　designed　and　the　parameters　were　optimized　through　the　orthogonal　experiments.　The　metals　of　(Si/Al),　V,　W　and　Mo　were　separated　step　by　step　with　the　precipitation　rates　exceeding　92%.　This　study　provided　a　reference　to　metal　comprehensive　separation　and　recovery　for　the　tungsten　secondary　resources.
