The paper describes a method of obtaining of Brown gas and extracting of minerals rich of polymetals. The obtained Brown Gas can successfully be used for regeneration of systems. The needed energy required to power the system drops sharply and energy efficiency rises. The extraction of Brown gas is accompanied by the release of a huge amount of minerals rich in polymetals, some of which exceed their content in natural sediments by several thousand times, and others are commensurated in content with natural polymetallic deposits.
