Title:
シュンガイトの精製方法
Document Type and Number:
Japanese Patent JP6791698
Kind Code:
B2
Abstract:
[Problem] To provide a shungite refinement method that can efficiently remove metals such as iron, metal compounds, and impurities such as sulfur from shungite ore so as to obtain highly pure shungite. [Solution] A shungite powder is dispersed in water, and a magnetic field is applied to the shungite powder dispersed in the water to remove iron and iron compounds by adsorption. The shungite powder from which iron and iron compounds have been removed by adsorption is further bombarded with microwaves in water or in air to remove sulfur, thereby allowing higher purification to be achieved.
