Beneficiation studies were conducted on a Portuguese feldspar ore, in order to obtain final products capable of being used in the ceramic industry. A simple scrubbing operation is enough to break the lumps in the feed. The ore deposit contains ca 35 x 106 tonnes from which, by screening, three main products could be obtained.

But naturally mined quartz usually contains feldspar, mica, rutile, and other associated minerals, resulting in the low purity of quartz, which limits its use of quartz. Therefore, the purification of low-grade quartz ore by suitable beneficiation methods is the key to improving the utilization rate of quartz.

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). Then the ore passes to a three-stage, acid-circuit flotation process.
