HIGH-PURITY SILICATE MATERIAL COMPRISING COPPER SMELTING SLAG AS RAW MATERIAL AND METHOD OF PRODUCING THE SAME
PROBLEM TO BE SOLVED: To provide a method of reusing slag generated by in a copper smelting process.SOLUTION: Copper smelting slag is treated with aqueous solution comprising hydrochloric acid or nitric acid to generate hydrogel and dry it, to produce adsorbent comprising high-purity silicic acid. Furthermore, burning of the adsorbent provides conductive adsorbent and acid leaching provides adsorbent with a high surface area.
【課題】銅製錬工程で生じるスラグを再利用する方法を提供する。【解決手段】銅製錬スラグを塩酸又は硝酸を含む水溶液で処理しヒドロゲルを生成させ、乾燥することにより、高純度のケイ酸を含む吸着材を製造する。さらに該吸着材を焼成することにより導電性を備えた吸着材や、酸浸出することにより表面積の高い吸着剤となる。【選択図】図５
