To recover potassium from feldspar, a biowaste, i.e., eggshell, was used. The chief composition of eggshells is calcite. As it is a rich source of Ca, hence it is used with HCl to produce calcium chloride. Feldspar is an aluminosilicate mineral that bears potassium in the interstitial sites. To unlock the potassium from the interstitial sites, it was roasted with …

FAO (FAO, 2008) for Africa have major implications for the supply of potash to agriculture, more widely within the devel-oping world. This is because potash ores have a rather lim-ited distribution globally (Rittenhouse, 1979; Moores, 2009b), with the bulk of the world's potash mined in Canada, Europe and the Middle East.

Notes. This feldspar is being imported by Laguna Clay into North America (from India). It will be marketed as the successor to G-200 feldspar and its temporary substitute, the MFEL S3470 blend (Minspar/G-200HP blend).
