Process for treatment of selenium-bearing materials |
摘要 |
Selenium-bearing materials are treated to convert selenium values to water-soluble form in a process which comprises producing a wet pellet product of uniform composition having a specified moisture content and size from an aqueous slurry containing the selenium-bearing material and dissolved sodium carbonate-containing reagent. In a preferred embodiment the slurry is pH-adjusted to neutralize free acid and/or to precipitate nonferrous base metals.
