一、引言 对于复杂难选的多金属硫化物,寻求具有较佳效能的浮选工艺,一直引起国内外选矿工作者的研究兴趣。八十年代甚至以后相当长的时期,矿物及冶金工程面临着生态、能源、经济,即所谓三E(Ecology,Emergy,Economy)的挑战。由于原矿品位越来越低,可供加工的矿物组分越来越复杂,因而,矿物工程受三E影响越来越突出。致使解决复杂多金属的分选这一重大课题,其难度显然越来越大。
I. INTRODUCTION The search for more efficient flotation processes for complex, refractory polymetallic sulphides has aroused the interest of the beneficiation workers at home and abroad. In the 1980s and even after a long period of time, mineral and metallurgical projects faced the challenges of ecology, energy and economy, the so-called Ecology, Emergy and Economy. As the ore grade becomes lower and lower, the mineral components available for processing become more and more complex, and as a result, the mineral engineering is more and more affected by the triple E effect. As a result, it is obviously more and more difficult to solve the major issue of the sorting of complex polymetallics.
