摘要

Process for the production of ferric chloride from an aqueous solution of hydrochloric acid and iron ore, the use of limonite or limonite with product of iron oxide as raw material in a production process of ferric chloride, ferric chloride thus obtained and their uses.The present invention relates to a process for the production of ferric chloride (FeCl3) in conventional reactors using only agitation and heating during the reaction, from an aqueous solution of hydrochloric acid (HCl) and iron ore, particularly limonite or limonite with production To iron oxide.The present invention also refers to the use of limonite or limonite with product of iron oxide as raw material in a production process of ferric chloride, ferric chloride thus obtained and their use in the treatment of drinking water, industrial wastewater and sewage. Also, to their use as coagulating agent and / or flocculant.
