Embodiment 1
[0021] A method for efficiently preparing lithium carbonate, the specific steps are as follows:
[0022] Step 1, pre-filtering the carbonated salt lake brine to remove solid suspended matter, and then adjusting the pH value to 3.6 to obtain the first liquid;
[0023] Step 2, add magnesium chloride to the first liquid and mix and stir evenly at a rotating speed of 150rpm, separate solid and liquid, and the solid part is washed and dried to form a magnesium carbonate product, wherein the liquid part is evaporated and concentrated and kept in an electric field of 1.65KV for 39 Minutes to make the second liquid;
[0024] Step 3, add sodium hydroxide solution to the second liquid and stir to mix evenly, and separate solid and liquid to remove Mg 2+ , Fe 3+ 、Al 3+ , to obtain the third liquid;
[0025] Step 4, the third liquid, the aqueous dispersant and the loofah extract are fully stirred in the hydrothermal synthesis reaction kettle and then sealed, the loofah extract is brok...
Embodiment 2
[0029] A method for efficiently preparing lithium carbonate, the specific steps are as follows:
[0030] Step 1, pre-filtering the carbonated salt lake brine to remove solid suspended matter, and then adjusting the pH value to 4.4 to obtain the first liquid;
[0031] Step 2, adding magnesium chloride to the first liquid and mixing and stirring evenly, separating the solid and liquid, washing and drying the solid part to form a magnesium carbonate product, wherein the liquid part is evaporated and concentrated and kept in an electric field of 1.65KV for 44 minutes to produce the second Two liquids;
[0032] Step 3, add alkaline solution to the second liquid and stir to mix evenly, and separate solid and liquid to remove Mg 2+ , Fe 3+ 、Al 3+ , to obtain the third liquid;
[0033] Step 4: Treat the third liquid in a microwave with a power of 88W for 22 minutes, then fully stir it with an aqueous dispersant and a loofah extract in a hydrothermal synthesis reaction kettle, and ...
Embodiment 3
[0037] A method for efficiently preparing lithium carbonate, the specific steps are as follows:
[0038] Step 1, pre-filtering the carbonated salt lake brine to remove solid suspended matter, and then adjusting the pH value to 4.5 to obtain the first liquid;
[0039] Step 2: Add magnesium chloride to the first liquid and mix and stir evenly, separate the solid and liquid, wash and dry the solid part to form a magnesium carbonate product, wherein the liquid part is evaporated and concentrated and kept in an electric field of 1.72KV for 40 minutes to produce the second Two liquids;
[0040] Step 3, add potassium hydroxide solution to the second liquid and stir to mix evenly, and separate solid and liquid to remove Mg 2+ , Fe 3+ 、Al 3+ , to obtain the third liquid;
[0041] Step 4, treat the third liquid in a microwave with a power of 86W for 22 minutes, then fully stir it with cationic polyacrylamide and loofah extract in a hydrothermal synthesis reaction kettle, and then se...
