摘要：

Processes are examined for fine purification of metallurgical-grade gallium recovered from various semiconductor waste materials based on GaAs and GaP. A classification is proposed for major Ga-containing waste materials. With allowance made for the behavior of impurities during the purification of metallurgical-grade gallium by different techniques, a multistep process is devised for preparing high-purity (99.9999%) gallium. The products of this process compare well with materials produced from conventional starting reagents and are suitable for the preparation of high-quality compound semiconductors.
