Nepheline Syenite—An Alternative Source for Potassium and Aluminium.5% SiO.. Chloridising-roasting experiments were carried using CaCl. at 900 °C for 1 h and water leaching at ambient temperature for 1 h. The leach liquor contains impurities like Ca and Na; hence, selective extraction of potassium was carried out through precipitation using perchloric acid at freez

Leaching and Recovery of an Oxide Gold Concentrate Using Ammoniacal Thiosulfate Solutions the leach solution, and an adsorption efficiency of 99.3% gold and 39.4% copper was attained. Two-step elution process, including pre-elution of copper with 0.5 mol/L (NH.).S.O. followed by gold elution with 2 mol/L NaCl + 0.5 mol/L Na.SO. was adopted, and 98.6% of copper and 99.1% of gold could be successfully eluted from the resin.
