ABSTRACT
Since 1991 the nonferrous metallurgy of Russia has experienced significant difficulties connected to a general crisis of reforming the national economy. From 1990 up to 1998 the extraction of the nonferrous metals’ ores has decreased as a whole by 42%, the manufacture of lead concentrate-by 3,9%, and zinc-by 23%. The available polymetallic ore reserves reduced in time (figure 1), which was due to the fact of their occurring in favorable mining-geological and economic-geographical conditions, on the one hand, and the constant increase of the industry need for lead and zinc-on the other hand, assume in the future an organization of highly profitable feature methods available also in the earlier not featured reserves of poor and balanced polymetallic ores and rational use of bowels in the working polymetallic mines.
