据日本媒体《日刊工业新闻》报道,日本法政大学明石孝也教授的研究组开发出以高浓度从矿石等物质中提取微量金属镓的技术。除矿石外,利用该技术也可以从废旧电子设备等镓含量较少的物质中回收金属镓。明石教授研究组开发的回收方法称为“碳素热还原-氧化法”。回收装置包括蒸发和采集两个部分。由硅、铝等构成并含有微量镓的火成岩在蒸发部分被高温氮气加热到1 150℃时,矿石中的镓元
According to the Japanese media, “Nikkan Kogyo Shimbun,” a research group led by Professor Akashi Miyazaki of Japan’s Hosei University has developed a technology to extract trace amounts of gallium from minerals such as ore at high concentrations. In addition to ore, this technology can also be used to recover metallic gallium from substances with less gallium, such as used electronic equipment. Professor Akashi research group developed a recycling method called “carbon thermal reduction - oxidation method.” Recycling devices include evaporation and collection of two parts. Igneous rocks consisting of silicon, aluminum and the like containing a trace amount of gallium are heated to 1,150 ° C by the high-temperature nitrogen gas in the evaporation section, and gallium
