摘要

Process for the production of ferrous sulfate and ferrous sulfate lu00ecquido concentrate their lu00ecquido concentrate obtained. This invention describes a process for the production of ferrous sulfate in concentrated liquid from the acid rock drainage forced or acidic water leaching of pyrite.The ferrous sulfate liquid concentrate is produced from the aerobic and anaerobic biolixiviau00e7u00e3o consecutive leaching of metal sulfides from coal mining.The ferrous sulfate in concentrated liquid produced by the process of this invention can be used as a raw material for the production of inorganic pigments of iron oxide and / or as raw material for the production of ferric coagulants.
