Production of sodium dichromate from chromite |
| abstract |
An iron/chromium alloy, which may be produced by reduction of chromite ore, is reacted with oxygen to form a ferrochromium melt and a Cr2O3-containing slag, and the slag is digested with alkali (eg Na2CO3) and an oxidizing agent (eg O2) to produce sodium chromate which may be converted to sodium dichromate. <IMAGE> |
