Electrolytic Manganese Hlau Ua Li Cas?

Q: Lub cev muaj zog ntawm electrolytic manganese flake purity density hardness?
A: Purity >99,7% yog '; ceev ~ 7.2–7.4 g / cm³; kuj mos thiab malleable.

Q: Tshuaj muaj pes tsawg leeg ntawm electrolytic manganese flake raug impurity qib?
A: Tsawg Fe, S, P, C; raug impurities<0.1% each, depending on grade.

Q: Melting point thiab boiling point ntawm electrolytic manganese flake?
A: Melting point ~ 1246 degree; Kub taw tes ~ 2061 degree.

Q: Corrosion kuj thiab oxidation tus cwj pwm ntawm electrolytic manganese flake?
A: Yooj yim oxidizes hauv huab cua; yuav tsum tau khaws cia tiv thaiv los ntawm noo noo thiab oxygen.

Kev tsim khoom muaj xws li mining, leaching, purification, thiab electrowinning:

Kauj ruam -los ntawm - Cov txheej txheem

Mining & Ore Npaj

Manganese ores (pyrolusite MnO₂, rhodochrosite MnCO₃) yog mined thiab crushed.

Leaching

Ore reacts nrogsulfuric acidntawm qhov kub siab kom tsim tau MnSO₄:

MnO2+2H2SO4→MnSO4+SO2↑+2H2O

(For MnCO₃: MnCO₃ + H₂SO₄ → MnSO₄ + CO₂↑ + H₂O)

Kev huv huv

Tshem tawm Fe, Al, hnyav hlau (Co, Ni, Pb, Zn):

Kho pH nrog txiv qaub → precipitate Fe(OH)₃, Al(OH)₃.

Ntxiv sodium sulfide → precipitate hnyav hlau sulfides.

Lim kom tau cov tshuaj MnSO₄ purified.

Electrowinning (Core Kauj ruam)

Purified kua nkag mus rau hauv cov hlwb electrolytic:

Anode: Lead-alloy grid (Pb-Ag, Pb-Ca-Sn)

Cathode: Stainless hlau ntawv

Cov xwm txheej90-95 degree, MnSO₄ 35–45 g/L, H₂SO₄ 10–20 g/L, tam sim no ceev 200–500 A/m², voltage 4–5.5 V.

Cov tshuaj tiv thaiv ntawm cathode:

Mn2++2e−→Mn (hlau)

Cov tshuaj tiv thaiv ntawm anode (oxygen evolution):

2H2O→O2↑+4H++4e−

Stripping & Ua

Tom qab 24-72 teev, nws yog xim hlau manganese stripped los ntawm cathodes li flakes.

Washed, dried, and packaged. Purity > 99.7 %.
