Slime content of feldspar ore originating from ore formation is a major cause of impurities due to its mica and heavy mineral content. Therefore, slime removal or desliming in feldspar flotation is a necessary process step. In many researches and plant applications, in order to improve concentrated product quality in feldspar flotation, the ...

2. Ore washing and desliming The washing process is suitable for feldspar produced from weathered granite or feldspar placer, which mainly to remove impurities such as clay, fine mud and mica. On the one hand, it can reduce the content of Fe2O3 in feldspar ore, on the other hand, it can increase the content of potassium and sodium in feldspar ore.

Feldspar for ceramic/glass industries requires sufficiently low content of harmful colourants (Fe-, Ti-, Mn-bearing mineral phases). Hydrothermally altered albite-rich granites are increasingly used as feldspar raw material nowadays; however, they are often marked by increased content of colourants, which must be removed during the …

Feldspar is especially abundant in igneous rocks (e.g. granite). Granitic rocks may contain up to 60% of alkali rocks; however, commercial feldspar is mostly mined from pegmatitic or feldspathic sand deposits. Pegmatites are intrusive igneous rocks known for their coarse texture. The most famous pegmatites have a combination of gigantic crystal ...
