1、東北大學(xué)碩士學(xué)位論文摘要收率為74．39％；尾礦產(chǎn)率為61．44％，尾礦中B203品位為3．44％，試驗(yàn)指標(biāo)較好，達(dá)到預(yù)期目標(biāo)。最后，利用紅外光譜、ZETA電位、SEM等表征手段，通過(guò)對(duì)浮選礦物的表面吸附、電動(dòng)力學(xué)及溶液化學(xué)的分析，對(duì)浮選藥劑與礦物之間的作用機(jī)理及浮選過(guò)程進(jìn)行了初步探討。本研究實(shí)現(xiàn)了低品位硼鎂石的浮選分離，對(duì)低品位硼鎂石資源的回收利用具有一定的指導(dǎo)意義。關(guān)鍵詞：硼鎂石；蛇紋石；浮選；FLM3．IV．東北大學(xué)碩士學(xué)位論文AbstractResearchonFlotationProcessingTechnol
