5 M H2SO3 added as a reductant. The double step of CoCO3 precipitation using 1.5 M Na2CO3 and conversion to COH)2 using 8 M NaOH allows a high purity product (99.5% purity) to be produced with most of the major impurities as Cr and Fe remaining in the residual Na2CO3 and NaOH liquors. The levels of these major impurities are 0.05% Cr and 0.3% Fe in the final Co hydroxide product.Implications This is a new process to treat W-Co wastes and recover W and Co. To the best of our knowledge, no study was done before in this ar
