Process for extracting Boron from Brine of natural or industrial using solvent extraction

摘要

Process for extracting Boron content in natural Brine or industrial, which may also contain Lithium, sodium, calcium, Magnesium, potassium, Chlorine, sulphates and Nitrates,Among other elements and components.The process comprises, basically, the first stage of acidulation of LASALMUERA at a pH of between 0.1 to 6.0, at a Dilution of 1 part in 10 Brine WaterUsing an Acid such as Sulphuric Acid or any other oclorhu00eddrico.A Second Stage extraction, which contact the acidified Brine in one or more stages of empleandocomo extractant, solvent extraction,At least one diol with 6 to 20 carbons in its structure, alone or in combination with a higher aliphatic Alcohol and, Optionally, with unmodificador phasesThis extractant or combination of them dissolved in an organic Solvent of aromatic Solvent in a reason extractanteorgu00e1nico between 1 / 10 and 1 / 1 and a reason to buy organic / aqueousDida between 1 / 10 to 10 / 1, and the contact time between 1 to 60 minutes.Temperature between 0 and 80 degrees centigrade; obtaining a Brine substantially free of an organic loaded with Boron and Boron.A third stage of re Extraction and stripping, contacting the Organic Boron loaded with an Alkaline solution with a pH between 7 and 14,Using a professional Reason acuosoentre / 1 / 10 and 1 / 10 with a contact time in each stage of re extraction from 1 to 60 minutes, at a temperature between 0 and 80 degrees centigrade.Alternatively, the process can include washing steps with an aqueous solution of organic acid to remove other impurities, such as gels, precipitates or CRATE.
