摘 要: 在礦物浮選過程中，金屬離子發(fā)揮著重要的作用，特別是活化浮選作用。在氧化礦的金屬離子活化浮選過程中，金屬離子與浮選藥劑形成的金屬-有機(jī)/無機(jī)配合物在礦物浮選過程中發(fā)揮了極大的作用，并在捕收能力和選擇性等方面體現(xiàn)出一定的優(yōu)勢。本文總結(jié)了苯甲羥肟酸鉛配合物、油酸鈣、鹽化水玻璃、金屬離子改性淀粉等在浮選領(lǐng)域的研究進(jìn)展，并從金屬離子配位調(diào)控分子組裝的角度，提出金屬離子在礦物浮選過程中的新作用機(jī)制。金屬離子具有良好的模板效應(yīng)，可以定向調(diào)控金屬配合物結(jié)構(gòu)實(shí)現(xiàn)功能組裝，這一功能為新型浮選藥劑的設(shè)計與開發(fā)提供了新的思路。

Abstract:Metal ions play an important role in mineral flotation, especially in activation flotation. Recently, some studies show that metal-organic/inorganic complexes form by metal ions and flotation agents play important role in mineral flotation. The metal-organic/inorganic complexes show certain advantages over the traditional flotation reagents in terms of collecting capacity and selectivity. This paper summarizes the application of lead benzohydroxamic acid complex, calcium oleate, water glass modified by metal ions, and modified starch-in mineral flotation separation. Metal ions are good templates for molecular assembly and can be used to control the structure of metal complexes and get some special properties. This function provides a new idea for the design and development of new flotation agents.
Key words: metal ion; coordination compound; coordinate assembly; activation theory; flotation reagents
