  Hydrometallurgical Recovery of Germanium from Coal …

  2008322 · Abstract This article is concerned with a simple hydrometallurgical method for the selective recovery of germanium from fly ash (FA) generated in an integrated gasification with combined cycle (IGCC) process. The method is based on the leaching of FA with water and a subsequent concentration and selective separation of germanium by a …

  Single-Step Hydrometallurgical Method for the Platinum …

  2020422 · The hydrometallurgical process consists of two main stages, the leaching stage, where metals are leached from their ores in an aqueous media, and the separation stage, where the leached metal complexes are extracted from the pregnant solution. After separation, further refining steps lead to noble metals of high purity.
