Alkaline Extraction of Organomineral Potassium Humate from Coal Mining Waste

Organomineral potassium humate was extracted from coal mining waste the Lenger deposit (Turkestan region, Kazakhstan) by alkaline extraction using an aqueous solution of hydroxide. The time and temperature process were investigated for degree yield product. A comprehensive study physicochemical properties raw material resulting production carried out chemical analysis, scanning electron microscope, energy dispersion, IR-Fourier spectrometric X-ray diffractographic analyses. maximum product wasachieved at 80 °C 90 min. Moreover, experimental data subjected to kinetic processing, as a result which it established that occurs in external diffusion region.
