Sep 19, 2018

1. Cov tshuaj chlorine oxidation yuav tuav ntau tshaj 100 mesh ntawm cov kua txiv manganese ore hmoov (los yog rov qab los ntawm manganese dioxide), raws li qhov sib piv ntawm 1: 0.9 ~ 1: 1.10 thiab caustic soda tov, diav hauv 400 ~ 500 ℃ oxidation roasting 8 ~ 12h, yog li hais tias manganese dioxide hloov mus rau hauv sodium permanganate, thiab ces dej los yog dej cawv tom qab leaching,

Hauv 93 ~ 95 ℃ cov tshuaj chlorine, kom txog thaum tus nqi phom ntawm 6.5 ~ 6.8, muab cov kua sodium permanganate tov, thiab tom qab ntawd los ntawm cov evaporation concentration, crystallization, centrifugation sib cais, zus tau cov khoom siv Crystal cov khoom tiav.

2. Qhov sib cais ntawm cov kab mob barium permanganate thiab sodium sulfate tom qab rov ua dua recrystallization, lim tawm lub barium sulfate, cov concentrated filtrate, txias, crystallization, uas yog, peb hydrates.

3. Pyrolusite los yog rov qab los ntawm manganese dioxide thiab caustic soda sib tov, by roasting oxidation, yog li ntawd manganese dioxide hloov mus ua sodium permanganate, thiab ces yaj thiab los ntawm cov tshuaj ua kom sodium permanganate ntxiv oxidation, npaj ua siab manganese acid sodium.
