Vb. Chernogorenko et al., Electrochemical processing of scrap tungsten-cobalt refractory alloys in sulfuric acid solution, RUS J AP CH, 72(6), 1999, pp. 1005-1007
Principles were developed of a technology for electrochemical processing of
scrap hard metals of the VK type and high-density tungsten-cobalt alloys,
based on anodic dissolution of the alloys in aqueous sulfuric acid solution
s containing additions of hydrochloric acid or metal chlorides.
