How to prepare manganese carbonate from used batteries

Summary. Hello, glad to have your question. Manganese carbonate plays an important role in batteries**.

First of all, it can be used as a stable battery material to provide long-term battery performance. Secondly, manganese carbonate has good corrosion resistance, which can prevent damage to the metal parts in the battery, so it plays an important role in the battery**. In addition, manganese carbonate can also reduce residual mercury ions in batteries, preventing them from having adverse effects on the environment.

Finally, manganese carbonate can be used as a charging substance for batteries to maintain the normal operation of batteries, thereby improving the reusability of batteries and reducing battery pollution. If mine can help you, I hope you will give me a thumbs up. Have a great day!

I'm still a little confused, can you be more detailed?

Okay, I'll explain it to you in detail. Manganese carbonate plays an important role in batteries**. First of all, it can be used as a stable battery material to provide long-term battery performance.

Secondly, manganese carbonate has good corrosion resistance, which can prevent damage to the metal parts in the battery, so it plays an important role in the battery. In addition, manganese carbonate can also reduce the residual mercury ions in the battery, preventing its adverse effects on the environment. Finally, manganese carbonate can be used as a charging substance for batteries to maintain the normal operation of batteries, thereby improving the reusability of batteries and reducing battery pollution.

If you still don't understand something, please feel free to ask.

The role of manganese carbonate in the battery is to provide the electrolyte of the battery, as well as the electrolyte in the electrolyte of the battery. The workarounds and steps for battery ** are as follows:1

First, the battery is taken apart, the electrolyte in the battery is collected, and the electrolyte in the battery is collected. 2.Then, the manganese carbonate in the electrolyte is separated and separated.

3.Finally, manganese carbonate is processed and reused. Manganese carbonate is an important electrolyte, which can be used to provide the electrolyte of the battery, as well as the electrolyte in the electrolyte of the pure front battery.

Therefore, manganese carbonate plays an important role in batteries**.

Manganese carbonate is prepared by introducing carbon dioxide and ammonia into the manganese salt solution.

（1）mno2

It has strong oxidizing property and reacts with concentrated hydrochloric acid to form chlorine gas, and the ion equation of the reaction is mno2+4H++2C1-

mn2++c12

2H2O, chlorine is toxic and cannot be directly emitted into the air, so the answer is: mNO2+4H++2C1-

mn2++c12

2h2o；produces toxic chlorine gas;

2) Hydrogen peroxide has strong oxidizing properties, which can oxidize reducing Fe2+ to Fe3+, which is easily converted to Fe(OH)3

And remove, so the answer is: Fe2+

Converted to Fe3+

3) Add concentrated hydrochloric acid, only the carbon black does not react, can be filtered and separated, add enough H2O2 solution to the filtrate and add NaOH solution to adjust the pH of the solution, Fe(OH)3 precipitate can be generated, so the answer is: C; fe（oh）3

4) From the data in the table, it can be seen that adjusting the pH of the solution between can make Fe3+ completely precipitate and prevent Mn2+

Converted to mn(OH)2

precipitation, so the answer is:; Make Fe3+

Precipitate completely, and prevent Mn2+

Converted to mn(OH)2

Precipitation; (5) Filtration The filtrate contains Mn2+, add a sufficient amount of H2O2 solution and add NaOH solution to adjust the pH to about 9, so that Mn2+ oxidizes to obtain MnO2, and the ion equation of the reaction is Mn2++H2O2+2OH-=Mno2

2H2O, so the answer is: mn2++h2o2+2oh-=mNO2

2h2o．

mn2+c12

2H2O, chlorine is toxic and cannot be directly emitted into the air, so the answer is: mNO2+4H++2C1-

mn2+c12

2h2o；Produces toxic crude chlorine gas;

2) Hydrogen peroxide has strong oxidizing properties and can oxidize reducing Fe2+ to Fe3+

It is easily converted to Fe(OH)3

And remove, so the answer is: Fe2+

Converted to Fe3+

3) Add concentrated hydrochloric acid, only the carbon black does not react, can be filtered and separated, add enough H2O2 solution to the filtrate and add NaOH solution to adjust the pH of the solution, Fe(OH)3 precipitate can be generated, so the answer is: C; fe（oh）3
