Claims (2)

1. Способ извлечения палладия, платины, серебра, иттрия, церия из глинисто-солевых отходов в виде шламов калийных предприятий, содержащих щелочные металлы, включающий их обогащение путем отмывки до содержания хлоридов щелочных металлов от 15 до 30%, с получением коллективного концентрата, концентрат гранулируют и подвергают обжигу, в качестве глинисто-солевых отходов используют складированные флотационные шламы, которые после отмывки сушат, при этом концентрат обогащения после сушки и гранулирования, обжигают,  после чего проводят измельчение полученного огарка до крупности 0,1 мм, затем проводят обесшламливание от глинистых частиц для получения концентрата обогащения огарка в виде песков, отличающийся тем, что коллективный концентрат обогащения после сушки и гранулирования обжигают при температуре 880°С, затем из полученного огарка извлекают интерметаллиды палладия, платины, серебра, меди, олова, свинца, а также интерметаллиды иттрия и церия.1. A method for extracting palladium, platinum, silver, yttrium, cerium from clay-salt waste in the form of sludge from potash enterprises containing alkali metals, including their enrichment by washing to a content of alkali metal chlorides from 15 to 30%, obtaining a collective concentrate, concentrate granulated and subjected to firing, stored flotation sludge is used as clay-salt waste, which is dried after washing, while the enrichment concentrate after drying and granulating is fired, after which the resulting cinder is crushed to a size of 0.1 mm, then deslimed from clayey particles to obtain a cinder enrichment concentrate in the form of sands, characterized in that the collective enrichment concentrate, after drying and granulating, is fired at a temperature of 880°C, then palladium, platinum, silver, copper, tin, lead intermetallides, as well as yttrium intermetallides, are extracted from the resulting cinder and cerium. 2. Способ извлечения палладия, платины, серебра, иттрия, церия из глинисто-солевых отходов в виде шламов калийных предприятий, содержащих щелочные металлы по п.1, отличающийся тем, что после сушки и гранулирования производят обжиг при температуре 880°С в течение 5 часов. 2. A method for extracting palladium, platinum, silver, yttrium, cerium from clay-salt waste in the form of sludge from potash enterprises containing alkali metals according to claim 1, characterized in that after drying and granulation, firing is carried out at a temperature of 880°C for 5 hours.
