Construction of a Green-Comprehensive Evaluation System for Flotation Collectors

The evaluation of flotation reagents performs an important role in the selection and green application reagents. indexes effect collectors were selected by data literature method, system analysis mathematical model qualitative quantitative collectors, system, comprehensive established. normalization method expert methods adopted to obtain grade classification indicators, respectively. analytic hierarchy process (AHP) was used determine weight secondary indicators tertiary at a lower level. Applying fuzzy (FCE), trapezoidal function is index affiliation, score calculated according weighted average principle, finally, established applied example. example shows that can make from aspects greenness reagent, effect, cost, it has strong target practicality for evaluation. establishment guiding significance use collectors.
