1/1/2009, · The total recovered ,precipitate, was estimated to be 90% of the theoretical mass expected as metal sulfides. The ,precipitate, was mainly recovered from the bottom of the reactor and the equalizer. The analysis of the precipitates showed the presence of pyrite (FeS2), sphalerite (ZnS) and greenockite (CdS); no metal hydroxides or carbonates in crystalline phases were identified.
