Abstract

Abstract

In this study, K₂MgSiO₄ mineral fertilizer were prepared by solid-phase sintering method with the high magnesium iron tailings from Laiyuan Area, Hebei Province. The dissolution release characteristics and simulated sustained-release performance of K₂MgSiO₄ mineral fertilizer were further investigated.The dissolution efficiency of K, Mg and Si prepared in water, 20 g/L citric acid and 0.5 mol/L HCl was significantly improved. The cumulative release amounts of K and Si in water, 20 g/L citric acid and 0.5 mol/L HCl reached 33.75%, 73.84% and 93.81%, 26.05%, 56.13% and 83.09%, 2.00%, 45.01% and 72.04%, respectively. The main nutrient elements can be released well and slowly, indicating that it can become a mineral fertilizer with excellent properties.
