A process for maturing strong beverages comprising activation of an oak stave after separation of a matured strong beverage therefrom by a cyclic application of a multimode electromagnetic field of standing waves with a frequency of from 2,000 to 4,500 MHz thereto to a heating temperature of from 35.degree. to 55.degree. C. At the same time, an oxygen-containing medium is purged. As a result of the cyclic application of the multimode electromagnetic field the stave releases the spirit vapors in a residual content thereof ranging from 5 to 10%. Between cycles of application of the multimode electromagnetic field the stave is cooled to a temperature of 15.degree. to 25.degree. C. by means of an oxygen-containing medium. The spirit vapors are entrained by the oxygen-containing medium and condensed. The strong beverage is kept in the activated oak stave. The matured strong beverage is then from the stave.

A method for processing heavy nonferrous metal raw materials by heating and melting said raw materials in a molten slag with the formation of a heterogeneous melt consisting of a sulfide and an oxide phases. The melt is bubbled oxidized by injecting a gas containing not less than 35% oxygen at an intensity of about 200 to about 2000 m.sup.3 STP/h per square meter of horizontal section of the melt, with the effect that the melt is divided into a top bubbled part and a bottom calm part comprising a slag layer, a matte layer and/or a crude metal layer, each of which is tapped separately. A furnace for putting said method into effect is a shaft terminating in its bottom part by a hearth and having devices for tapping smelting products, whereas the top part is provided with orifices for feeding a charge and removing gaseous smelting products. The furnace has cooled side tuyeres set at a level dividing the shaft into two vertical parts. The device for tapping slag from the bottom part of the slag layer is formed with a recipient communicating with the internal cavity of the shaft by means of a duct arranged below the tuyere level, but above the level of the matte inside the shaft. Said technological sequence of operations and the furnace design provide a possibility of separating polymetallic raw materials by a single-stage process into smelting products and denuded slag. It is most effective to employ the present invention for processing high-sulfur copper, nickel, copper-nickel and copper-zinc raw materials.
