Abstract
PURPOSE: To separation-recover Mo, W and Te as their hydrated oxides of high purity by oxidizing part of ferrous ions in waste water contg. Mo, W, Te and heavy metals to precipitation-remove the ions together with the heavy metals and by adjusting the residual soln. to pH≤2.
CONSTITUTION: To industrial waste water contg. valuable metals such as Mo, W and Te and other heavy metals is added ferrous sulfate and further added an about 30 % aq. soln. of caustic soda. The waste water thus adjusted to pH 8W12 is heated to 65°C and blown with air at a rate of 2 l/min to induce oxidation, forming black srinel type ferrite precipitates. The heavy metals such as Mn, Co, Ni, Cr, Zn, Cu and Cd are precipitated simultaneously. The ferrite precipitates are removed by magnetic separation, and the residual aq. soln. is adjusted to pH≤2 with hydrochloric acid. The Mo, W and Te in the aq. soln. precipitate as their hydrated oxides, which are then recovered by filtration and separation.
