Sustainable Process for the Extraction of Potassium from Feldspar

Mentioning 3 To recover potassium from feldspar a biowaste 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 calcium
