The feldspar group is one of the most common types of minerals in the earth's crust. Feldspar alteration (including the whole processes of feldspar dissolution, transfer of released solutes, and secondary mineral precipitation) is ubiquitous and important in fields including resources and environmental sciences.

2. Flotation process. The flotation process can effectively remove iron from clay and fine-grained iron-containing minerals, but the effect is not good for hard ores. For severely weathered ores, secondary sludge may be produced during the crushing and grinding stage, which may easily cause the flotation to be highly viscous, resulting …
