The mechanism by which SA acts as a depressant was proved to be its selective chelation with metals on the mineral surfaces. Considering that metal ions, such as Si 4+ and Al 3+, are abundant in the spodumene–feldspar flotation system, SA is a potential depressant for this system. However, there are no published papers concerning …
