Description	The scientists of the National Mining University of Ukraine were the first in the world to work out new highly efficient industrial technology of drill bits and diamond tools production from tungsten – and – cobalt alloys by means of secondary raw material direct regeneration and material direct regeneration and without any thermochemical methods application. One of the important sources of a partial satisfaction in wolfram is solid alloy wastes which get concentrated at all enterprises which consume solid alloy in Ukraine. That's why the most important task under the present conditions is a development of new technologies on recycling wolfram containing wastes. The technology of mechanical grinding which excludes hydrometallurgical and zinc ways has been laid as a basis of solid alloy recycling. Wolfram-cobalt production wastes, wolfram-nickel armor-piercing mandrels and also pure wolfram items and carbide and bore ones are used as basic raw materials. Metal-ceramic solid alloys are among heterogeneous alloys in the medium of which there are surfaces where brakes of any microscope indices occur. The new technology combines technological streams of utilizing scrap iron and alloys, the production of reactive ampoules, the preparation of explosive mixture, regeneration, classification, thin grinding and baking, system realization of which provides the obtaining of the production.
