摘要

Abstract

The issues of reducing CO

emissions

sustainably utilizing naturalmineral resources

and dealing with industrial waste offer challenges for sustainable development in energy and the environment. We propose an efficient methodology via the co-reaction of K-feldspar and phosphogypsum for the extraction of soluble potassium salts and recovery of SO

with reduced CO

emission and energy consumption. The results of characterization and reactivity evaluation indicated that the partial melting of K-feldspar and phosphogypsum in the hightemperature co-reaction significantly facilitated the reduction of phosphogypsum to SO

and the exchange of K

(K-feldspar) with Ca

(CaSO

in phosphogypsum). The reaction parameters were systematically investigated with the highest sulfur recovery ratio of ~60% and K extraction ratio of ~87.7%. This novel methodology possesses an energy consumption reduction of ~28% and CO

emission reduction of ~55% comparing with the present typical commercial technologies for utilization of K-feldspar and the treatment of phosphogypsum.
