  2. 1. PLASMA EXPEDIENT OF REDUCTION OF MAGNETITE CONCENTRATES BY WOOD WASTES In some wood regions and, in particular, in Kareliya there was a following situation:  on the one hand there are stocks of ore raw materials, on the other hand are annually formed hundred thousand tons of organic wastes of a timber industry complex, which pollute a surrounding medium. However these wastes can be utilised as reduction raw materials for an iron and steel industry.  Therefore urgent the mining of technology allowing to solve simultaneous two problems is: to utillize organic wastes of manufactures of a timber industry complex and to manufacture mineral raw materials with reception of metals.  The metallurgy is manufacture with major energy consumptions, and the level of power inputs defines prospects of this or that metallurgical technology for practical embodying.

  6. 2. PLASMA PROCESSING OF WATER Now there is a problem of a decontamination and clearing of water. A serious problem is the replacement of chlorination of water by other methods of a decontamination.  It is revealed, that at chlorination of water there is a formation of chloric organic compounds, which have cancerogenic properties.  The given problem is sharp enough stands for wood regions, the water in which contains especially many organic impurities. One of the most effective expedients of destruction of organic impurities, is the plasma processing of water.  Thus theoretical and experimental research have shown, that in water plasma of electric discharge the appreciable quantity of fissile particles is formed, as well as at radiative action. Primary products will be fissile radicals H, OH, H2O2, O2, e-hydrate, and also various ions.  The research have shown, that the above-stated fissile radicals best are formed in nonequilibrium plasma of a glow discharge.
