DECOMPOSITION PROCESS OF CENTRAL KYZYLKUM PHOSPHORITE WITHOUT ACID IN THE PRESENCE OF A BIO-COMPONENT AND ANALYSIS OF ELEMENT SOLUBILITY
Keywords:
Central Kyzylkum phosphorite, bio-component, acid-free decomposition, ICP–OES, solubility.Abstract
In this work, the possibility of converting Central Kyzylkum phosphorite (CKP) samples into a soluble form under acid-free and environmentally safe conditions through heat treatment in the presence of a bio-component was studied. The experiments were carried out with bio-component ratios of 1:1, 1:2, 1:3, and 1:4 at temperatures up to 100°C. The composition of the obtained products was analyzed using an Avio 200 (ICP–OES) optical emission spectrometer. The results showed that the concentrations of Ca, Sr, Mg, K, Fe, P, and other elements consistently increased with the amount of bio-component.
