Hard-rock mining for feldspars is done by open-pit methods, either by the mine owner or by contractors. After the feldspar ore is drilled and blasted, secondary breakage is performed with a conventional drop ball. Ore is then loaded with a hydraulic shovel onto trucks and hauled to the crushing plant, which is adjacent to the flotation plant.

EP-2343131-B1 chemical patent summary.

The raw ore contains K2O 4.37%, Na2O 3.38%, Fe2O3 0.48%, SiO2 77.56% and Al2O3 12.13%. Feldspar is recovered by magnetic separation – flotation combined process. After impurity removal (removal of impurities such as iron, mica and mud), feldspar and quartz are flotation separated. After that, the secondary roughing, secondary sweeping ...

A froth flotation process is used for most feldspar ore beneficiation. Figure 11.27-1 shows a process flow diagram of the flotation process. The ore is crushed by primary and secondary crushers and ground by jaw crushers, cone crushers, and rod mills until it is reduced to less than 841 µm (20 mesh).

This has placed added pressure on producers to further optimize existing feldspar processing methods like flotation to more efficiently produce higher grades of feldspar for the specialty glass, ceramics and electronics markets. When manufacturing high-grade, colorless glass it is important to have very low levels of iron oxide in the feldspar.
