separation and beneficiation of feldspar from granitic rocks

SELECTIVE SEPARATION OF Na- AND K-FELDSPAR FROM

separation [8]. The suitability of weathered granitic rocks for the raw material of feldspar and silica sand indicated that granite is more useful than granodiorite as a raw material, because the former is rich in quartz and potash feldspar. Good results of feldspar flotation was obtained for granite compared to granodiorite. They also

This paper focuses on the beneficiation of the 500/74 µm fraction, which constitutes about 27% of the ore, assaying 9.42% Al2O3, equivalent to approximately ca 46% feldspar, with a mean iron content of 0.29% iron oxides. Magnetic separation and froth flotation testwork was carried out, in order to decrease the iron contamination and increase the

01/01/2000  The main sources of feldspar minerals are pegmatitic rocks and feldspar sands and, to a lesser extent, other acid granite differentiates such as aplites and eurites. Unfortunately the current trend in the ceramics market, namely increased production of porcelain stoneware tiles and a decline in the single fired tile sector, strongly disadvantages the poorer quality minerals (Benedusi, 1998; Bornioli,
