【摘要】 本文介绍了对攀西地区片麻岩型鳞片石墨进行碱煅烧法提纯的研究。探讨了碱煅烧法提纯过程中包括NaOH药剂用量、煅烧温度、煅烧时间、酸浸时间等的影响。经过碱煅烧法提纯,品位从原来的80.21%提高到97%以上。更多还原

【Abstract】 This passage introduces an experiment of purifying graphite which is gneisses type flake graphite from Panxi with alkali calcination,investigates the influencing factor in the alkali calcination process includes the dosage of NaOH,the temperature of calcine,the period of calcine and the period of acid etching.During the alkali calcination the grade is raised to upwards from 80.21% into more than 97%.更多还原
