| titleOfInvention | Salt lake brine treatment method for separating lithium from high-magnesium-lithium-ratio salt lake brine |
| abstract | The invention discloses a salt lake brine treatment method for separating lithium from high-magnesium-lithium-ratio salt lake brine. The treatment method comprises the steps that S1, the salt lake brine is subjected to multistage salt pan evaporation to form first old brine; S2, sulphur removal is conducted: lime milk is added to the first old brine for separating out gypsum, and second old brine is obtained; S3, the second old brine is subjected to salt pan evaporation, bischofite is separated out, and third old brine is obtained; S4, the third old brine is diluted, and sent to a nanofiltration membrane device for nanofiltration treatment, and contributing water rich in lithium and thick water poor in lithium are obtained; and S5, the contributing water in Step S4 is sent to a reverse osmosis membrane device for reverse osmosis treatment, and reverse osmosis thick water and fresh water are obtained. The method combines a salt pan technology with a membrane system, makes full use of solar energy, and reduces energy consumption; a technological process is simple; equipment is easy to configure, mount and transfer; popularization and an application are very easy. |
