Sposoby odzyskiwania metali szlachetnych z odpadów kopalnianych typu jarosytowego
2012
This article presents the goal and main tasks of the international project "Development of New Nanocomposites Using Materials from Mining Industry" realized at the Metal Forming Institute within the frame of the 7th Framework Programme. A method of fast break-down of jarosite waste, which constitutes the source of raw materials in the project, has been presented in the article. Jarosite waste were subjected to mechanical and chemical processing for the purpose of recovering the silver contained in them. The studies apply technology that ensures ecological safety and are economically efficient. Disintegration in jet mills made it possible to obtain grains of the desired size and to degrade existing agglomerates, and the chemical process in a fluidized-bed furnace caused an increase in the silver content in the waste.
