Flotation Chemistry（《浮選化學(xué)》）是全英文教材，主要內(nèi)容包含礦物加工工程專業(yè)學(xué)生必須掌握的浮選英文基本知識(shí)，以及英語寫作與表達(dá)的基本技能。
浮選體系中，酸、堿等化學(xué)藥劑的添加及礦物溶解等，使礦漿溶液中發(fā)生大量的化學(xué)反應(yīng)，而這些化學(xué)反應(yīng)在浮選過程中對(duì)浮選起到至關(guān)重要的作用。因此，本書在介紹浮選基本理論的基礎(chǔ)上，詳細(xì)介紹浮選化學(xué)基礎(chǔ)，之后分別介紹天然可浮性礦物、硫化物礦物、不能溶解的氧化物和硅酸鹽礦物、微溶鹽和可溶解鹽礦物的浮選化學(xué)。前言下方附二維碼，供學(xué)生下載專業(yè)詞匯，方便學(xué)習(xí)。
本書的主要特點(diǎn)是理論與實(shí)踐相結(jié)合，包含從基礎(chǔ)理論到實(shí)際應(yīng)用的內(nèi)容，可供礦物加工工程相關(guān)專業(yè)本科生及研究生，以及從事相關(guān)專業(yè)的工程技術(shù)人員參考使用。
