Selective lepidolite–quartz flotation using an environmentally benign collector dodecylbenzenesulfonate isopropanolamine activated by Ca2+

Efficient separation of quartz from low-grade lepidolite ores by flotation remains difficult because the two minerals share similar surface chemistry. In the present work, dodecylbenzenesulfonate isopropanolamine (LAS) was introduced as an environmentally benign collector, with C...
