Electrochemical processing of heavy tungsten alloy wastes (wt.%: W 78,8, Ni 15,2, Fe 6,0) under the cyclic using of direct and alternating current in ammonia-alkaline solutions has been investigated. High dissolution rate of alloy wastes, as well as degree of tungsten extraction, has been provided. The electrochemical process has been accompanied by production of microdispersed iron-nickel powder, that contains up to 2 wt.% tungsten.
