METHOD OF FORMING TECHNOGENIC DEPOSITS |
摘要 |
mining and ecology; applicable in storing of metal-containing rocks. SUBSTANCE: method includes formation of drained, concentrated and leached layers. Leached layer is formed from iron-containing rocks. Concentrated layer is formed from quality nonstandardized iron ores based on minerals-concentrators of iron possessing either negative charge with neutral character of metal-containing solutions or positive charge with alkali character of metal-containing solutions. Minerals-concentrators of iron are used in the form of manganese dioxide, or chromium or titanium oxide. EFFECT: increased efficiency of intradump concentration due to iron precipitation. 2 cl, 1 dwg
