Medical stone

After spectral analysis, in addition to trace elements, northern medical stone also contains boron, germanium, copper, zinc, tin, gallium, chromium, nickel, indium, molybdenum, vanadium, cobalt, niobium, tantalum, zirconium, selenium, beryllium, barium, sr, and rare earth elements lanthanum, cerium, yttrium, ytterbium and so on. Other elements are below the spectral detection limit. The radioactive elements uranium and thorium are above the Clark value. Harmful elements such as cadmium, lead, mercury and arsenic are also within the spectrum detection line.

Medical stone has adsorption, solubility, regulation, biological activity and mineralization. It can absorb metal ions free of water. After water immersion medical stone, can dissolve more than 40 elements, of which nearly 20 are trace elements, in addition, there are trace rare earth elements. Medical stone containing AL2O315%, as a neutral oxide, in aqueous solution with alkali (OH) reaction to reduce pH, acid (H) reaction to increase pH, so as to have the function of two-way pH regulation.

The geological work of Maifanshi mine lacks complete practical data. The exploration type and working distance of the deposit can be determined by referring to similar vein nonmetallic deposits. However, it is necessary to pay attention to the representativeness of deposit sampling, and the weathered, semi-weathered and primary zone ores should be sampled separately, and the performance and application of all kinds of ores should be evaluated.
