Abstract
Official abstract text for this publication.
Disclosed is a boron recovering device including: an aeration-type water-channel reactor including a water channel; at least one aeration unit disposed in the water channel and aerating a boron-containing solution by passing it through the water channel to deposit boron in the form of borax; and a precipitation bath precipitating the deposited borax in the boron-containing solution having passed through the aeration-type water-channel reactor and separating a filtrate by overflowing, a boron recovering device, a method of recovering boron, and a boron recovering system.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of recovering boron, comprising: depositing boron included in a boron-containing solution in a form of borax by aerating the boron-containing solution; controlling a pH value of the boron-containing solution to reach a predetermined pH range by feeding an acid into the boron-containing solution, wherein the predetermined PH range is from about 7.5 to about 9.5; precipitating the borax in the boron-containing solution to separate the borax from a filtrate by overflowing the filtrate; and discharging, by a rotary dump valve, the borax from the precipitation bath. 2. The method of claim 1 , wherein depositing the boron included in the boron-containing solution in the form of the borax comprises: feeding borax particles into the boron-containing solution. 3. The method of claim 2 , wherein feeding the borax particles comprises: feeding the borax particles at a weight ratio of about 0.01 to about 0.5 based on a boron content included in the boron-containing solution.
