FIELD: electrode production. SUBSTANCE: invention concerns manufacturing electrodes for electroerosion machining. Method includes pressing tungsten-containing charge and subsequent heat treatment thereof which is distinguished by that the charge is supplemented with copper-containing component, and, as tungsten- and copper-containing components, utilized are products of reduction and carbothermic synthesis involving tungsten- and copper-containing raw material flotation waste. The charge is summarily composed of 10-25 wt % of reduction product of tungsten-containing flotation waste, 10-25 wt % of product of carbothermic synthesis involving tungsten- containing flotation waste, and product of reduction of copper- containing flotation waste (the balance). EFFECT: reduced cost and widened choice of electrode constituents.
