摘要

Treatment of leaching after the ammonia processlateral FeNi ore processingdirect use as blast furnace charge is performedso that the chromium present is roastedat 1000 - 1100 ° C for additionsalkali and lime by oxidative roasting to solublethe mold and leaching is separated. Roastingand leaching is carried out with a pelletized charge.Leached solution containing chromiumsalt, is used as a raw material for productionsodium dichromate.
