    • The present invention provides a method of producing a pelletized composition containing leonardite, sedimentary rock and gypsum. The method calls for pre-mixing the humic substance and the sedimentary rock for at least two weeks to yield a developed mixture prior to addition of other materials such as gypsum and pelletizing and drying the pellets to produce the final product. The invention also includes several pelleted compositions containing leonardite, rock phosphate and gypsum. In one aspect of the invention the rock phosphate comprises a mixture of sedimentary rock phosphate and igneous rock phosphate. In another aspect of the invention, the igneous rock phosphate comprises carbonatite and the sedimentary rock phosphate comprises phosphorite.
    • 本发明提供一种生产含有莱ard石,沉积岩和石膏的颗粒组合物的方法。 该方法要求将腐殖质和沉积岩预混合至少两周,以在添加其它材料如石膏之前产生显影的混合物,并造粒并干燥颗粒以产生最终产物。 本发明还包括几种含有锂离子矿,磷酸岩和石膏的沉淀组合物。 在本发明的一个方面,岩石磷酸盐包括沉积岩磷酸盐和火成岩磷酸盐的混合物。 在本发明的另一方面,火成岩磷酸盐包括碳酸盐岩,沉积岩磷酸盐包括磷矿。
