dc.descriptionKnowledge of a rock’s composition allows for inferences regarding several properties, ranging from its physical characteristics to its solubili ty. This study aimed to evaluate the use of different extractants to solubilize the K present in rocks as a pote ntial source of nutrients and the effects of extractant contact time and temperature on rock solubilization. Samples of two rocks and a mineral concentrated from a granitic rock were treated wi th ammonium dihydrogen phosphate (NH 4 (H 2 PO 4 )), calcium dihydrogen phosphate (Ca(H 2 PO 4 ) 2 ), sodium hydroxide (NaOH) and wa ter (control). Sample-extractant treatments were performed using a wate r bath shaker at temperatures of 25 and 50°C for periods of 3, 7, 10, 20, and 30 days. The amounts of K extracted from rocks using the extractants were in the following order: NH 4 H 2 PO 4 >Ca(HPO 4 ) 2 >NaOH>water. The sequence of K release (ppm) based on the rocks studied was as follows: nepheline syenite>green banded argill ite>concentrated biotite. Increasing the extractant contact time and temperature enhanced the solubilized K content.
