Description
The leaching process of danburite concentrate with sodium hydroxide was studied in this article. The optimal conditions of leaching process of danburite concentrate by NaOH were found. The mineralogical composition of danburite concentrate by means of chemical and X-ray analysis were defined. The element analysis of danburite concentrate is presented. The standard thermodynamic quantities, including enthalpy, entropy and Gibbs free energy were calculated. The leaching process of initial danburite and its concentrate was studied depending on temperature, process duration and sodium hydroxide concentration. The temperature dependence was studied at temperature range 30-90 deg C. The process duration of leaching of danburite concentrate with NaOH was studied in intervals 30-120 min.
