The method of recovering cesium and rubidium extraction of lithium from the slag

The present invention provides a process for recovering cesium and rubidium extraction of lithium from slag process, the production process consists of the following composition: finely mashing ~ ~ ~ liquid-solid separation Extraction Enrichment - ~ ~ ~ a concentrated precipitate, rubidium, and cesium - melt hydrogenated ~ ~ ~ burning dissolved secondary drying was concentrated ~ ~ ~ crystallized in products, rubidium carbonate and cesium carbonate. It has the effect that: 1, can provide a large amount of the lithium salt of existing production process for waste utilization lithium left behind, great social benefits; 2, a high metal value recovery of cesium and rubidium, the total recovery rate of 80% above; 3, reduce production costs and energy consumption; 4, high product purity, are finally reach rubidium carbonate (99.9% min) and cesium carbonate (99.9% min) products.
