        石墨的可浮性好,目前多用浮选法。常用的浮选药剂是油、二号油、水玻璃、石灰等.由于石墨嵌布度大,因而磨矿细度粗,通常-100目占45-60%. 鳞片石墨多采用粗梢矿再磨再选的浮选流程,即先进行粗磨、粗选,得到以连生体为主的低品位梢矿(品位为40-50%),然后将低品位精矿再磨、再选得最终精矿.再磨次数为3-7次,一般3-4次.最终精矿品位一般在85-89%之间.为抑制黄矿、云母等共生矿物.可加石灰、糊梢、水玻璃等药剂. 除浮选外,还可采用静电选矿法。日本曾建立了一个电选实验厂,但处理能力较小.由于电选给矿需要干燥和精密分级,在潮湿环境中对高压电源难于管理,微细拉部分难于处理等原因,没有实际生产.最近报道,电选处理中碳石墨效果很好,精矿品位可达96%左右. 鳞片石墨也可用风选处理,但回收率不高.在严重缺水地区可用风选使石墨初步富集,然后将粗精矿送到水源丰富的地区精选,像新疆哈密石墨矿就适合用风选一浮选联合流程。
