Abstract. Basalt deposits of Rovno and Zhytomyr regions of the Ukraine contain native copper, oxides and carbonates of copper, native iron and titanomagnetite in the volumes which represent commercial interest. Therefore, it is very actual to develop the complex technology of processing of raw materials of basalt, this technology will provide not only the production of non-metallic building materials, but also will provide  extract of copper, iron, titanium. In the development of this technology we studied the process of electric separation of the main copper-bearing rocks -  basalt, tuff and lava-brecchia. On the basis of experimental data have been found the dependences and developed the generalized regression models for determination of the product output  of the electric separation process concentrate by changing size separator supply in the range ‒1.0 + 0.05 mm and a field voltage across the electrodes 10 ÷ 30 kW. The obtained results indicate the feasibility of using electric separation in the complex technology of processing basalt rock deposits of Volyn and allow to predict concentrate output at electric separation of basalt, tuff and lavа-breсchia.

Keywords: electric separation, yield of the concentrate, basalt, tuff, lava-brecchia.
