| titleOfInvention | Method for selective intradump concentration of substandard ores |
| abstract | FIELD: mining; applicable in intradump concentration of substandard tungsten- and arsenic-containing ores. SUBSTANCE: first, drainage layer is formed, then, successively, concentrated layer of substandard arsenic-containing ore being a geochemical barrier for arsenic, concentrated layer of substandard tungsten-containing ore which serves as a geochemical barrier for tungsten, and leached layer of rocks containing tungsten and arsenic. When leaching solutions are supplied, tungsten and arsenic are dissolved in the upper layer, migrated and precipitated in respective layers. Purified solutions are removed through drainage layer. EFFECT: higher efficiency. 4 cl, 1 dwg |
