3/4/2019, · Abstract. The mother solution of high purity ferric sulfate can be extracted by water washing, acid leaching, high-temperature aging, water leaching and removing K, Ca and Si elements with high content in sintering dust with sintering dust as raw material. Under the optimal acid leaching scheme, the leaching rate of Fe element can reach 99.8%.

The aim of this study was to explore the heavy-metal resistance and hydrocarbonoclastic potential of microorganisms in a hypersaline soil. For this, hydrocarbonoclastic microorganisms were counted on a mineral medium with oil vapor as a sole carbon source in the presence of increasing concentrations of ZnSO4, HgCl2, CdSO4, PbNO3, CuSO4, and Na2HAsO4. The colony-forming units counted …
