Problems solved by technology

At present, the methods for extracting boron from brine include: flotation method, adsorption co-precipitation method, ion exchange method, acidification precipitation method, step-by-step precipitation method, and solvent extraction method, among which solvent extraction method has been studied for a long time to extract boron, but For the mixed alcohol extraction of boric acid with monohydric alcohol and dihydric alcohol, there is no report in China
Diols are highly polar and have poor compatibility with non-polar solvents, so general organic solvents are not suitable as diluents

Embodiment Construction

[0005] Accurately pipette a certain amount of mother liquor and organic phase, place them in a separatory funnel according to a certain ratio, vibrate on an oscillator under certain conditions for a period of time, and then let it stand still. After the two phases are separated, take the water phase for analysis. The volume fraction of boric acid in the aqueous phase was measured, and the volume fraction of boric acid in the organic phase was obtained by subtraction method according to the conservation of materials. Among them, the mixed alcohols of isooctyl alcohol and 2-ethyl-1,3-hexanediol, and isoamyl alcohol and 2-ethyl-1,3-hexanediol are referred to as Da and Db respectively. All monohydric alcohols use sulfonated kerosene as a diluent, and isooctyl alcohol and isoamyl alcohol are referred to as MA and MB respectively. The experimental temperature is room temperature (20° C.). Determination methods of each element: boron is determined by alkali titration (mannitolizatio...

Abstract

The invention discloses a boron extraction technology. Brine water after extracting lithium from salt lake is used as raw paderial and 2-thyl-1,3-hexanediol respectively with mixture alcohol of isooctal alcohol and isoamyl alcohol extracts borone from the brine water and optimum processing condition for extracting boron from brine water using the mixture alcohol is obtained after performing experiments from the aspects of extractant volume fraction, acidity, phase ratio, extraction time, extraction temperature, saturation extraction volume, back washing agent concentration and back washing time: extractant volume fraction 30%, water phase pH 3, phase ratio 1:1, extraction time 10min, maximum saturation capacity 61.4g / L(B2O3).

Description

technical field [0001] The invention relates to an extraction boron extraction process. technical background [0002] Boron and its compounds are widely used in national economic construction, and the raw materials for their production mainly come from ore and brine. With the large-scale mining of boron ore, ore resources are increasingly exhausted. The salt lake contains a large amount of boron, mostly in the form of liquid ore. At present, the methods for extracting boron from brine include: flotation method, adsorption co-precipitation method, ion exchange method, acidification precipitation method, step-by-step precipitation method, and solvent extraction method, among which solvent extraction method has been studied for a long time to extract boron, but For the mixed alcohol extraction of boric acid with monohydric alcohol and dihydric alcohol, there is no report in China. Dihydric alcohols are highly polar and have poor compatibility with non-polar solvents, so gene...
