    摘要:

    鑒于粉煤灰潛在的應(yīng)用價(jià)值，粉煤灰循環(huán)再利用為兼顧經(jīng)濟(jì)和環(huán)保效益提供了絕佳的機(jī)會(huì)。本文全面的闡述了從預(yù)脫硅堿石灰燒結(jié)法生產(chǎn)氧化鋁過(guò)程中提取鎵的生產(chǎn)工藝。采用螯合離子交換樹(shù)脂從鋁濃度較高的種分母液中選擇性分離低含量的鎵，并對(duì)吸附數(shù)據(jù)進(jìn)行了玻爾茲曼分布擬合及分析。文中還對(duì)工藝中孔蝕問(wèn)題和玻璃鱗片的防腐性能進(jìn)行了研究。

    Abstract:

    Recycling coal fly ash provides the perfect opportunity to achieve the significant economic and environmental benefits because of the vast number of potential applications. A production procedure is reported for the recovery of gallium from production of alumina from high-alumina coal fly ash with predesilication and lime-soda sinter combination process. The present paper gives a comprehensive description of the whole process. The low concentration of gallium in the spent liquor, along with the high concentration of aluminum, prompted the use of chelating ion exchangers as an alternative separation process. Gallium extraction studies were carried out using chelating ion exchangers. The experimental data were simulated and analyzed by Boltzmann distribution function. The paper also deals with the pitting corrosion of carbon steel as well as the studies carried out on the glass flake mortar resistant to corrosion.
