Abstract: PURPOSE:To obtain the titled iron oxide powder economically, from the zinc- leaching residue produced as a by-product of wet zinc refining, by leaching the residue with an acid in reducing atmosphere, separating and removing Al, Si, As, etc., from the leachate, precipitating iron from the liquid by oxidation and purifying the precipitate. CONSTITUTION:The zin-leaching residue produced as a by-product of wet zinc refining process is leached with an acid in a reducing atmosphere, and the leachate is neutralized, bubbled with oxidizing gas and separated into solid and liquid.A part of the ferrous compound in the liquid is oxidized and the most parts of Al, SiO2 and As are coprecipitated with iron and removed. Zinc powder is added to the system in the presence of copper ion to effect the precipitation and removal of arsenic in the from of copper arsenide. The leachate is made to react with oxidizing gas in an autoclave at >=100 deg.C, and the precipitated iron compound composed mainly of iron alpha-oxyhydroxide is separated and subjected to the hydrothermal decomposition at >=150 deg.C. The impurities such as Na, K, Zn, etc., are dissolved, and iron is precipitated and separated in the form of hematite and is subjected to desulfurization, calcination and disintegration.
