| titleOfInvention | Utilize the method for ferrochrome preparation chrome oxide green |
| abstract | The present invention relates to a kind of methods using ferrochrome preparation chrome oxide green, comprising steps of providing electrolysis unit, including electrolytic cell, twin cathode device, double anode device, insulating barrier, multiple subsiders and electrode；Cell reaction is carried out using self-circulation mode, is controlled automatically at 20 DEG C~60 DEG C, the time of electrolyte circular response is controlled according to formula 1, High chromium concentration acid salt solution is obtained after separation of solid and liquid；High chromium concentration acid salt solution is imported in reaction kettle and carries out hydro-thermal reaction, under the pressure of 2MPa~10MPa, is heated at a temperature of 180 DEG C~280 DEG C, hydro-thermal reaction slurry is obtained after reacting 2h~12h, is separated by filtration to obtain chromium hydroxide solid；It calcines chromium hydroxide solid to obtain chrome oxide green. |
