Tourmaline is silicate mineral containing boron cyclic, having a piezoelectric or pyroelectric properties, but also has a far-infrared emission and release the anion, has been widely in many fields of environmental protection, health, textiles, building materials and agriculture application. In this paper, chemical analysis, rock and mineral identification, X-ray diffraction analysis (XRD), infrared spectroscopy (IR), differential thermal analysis (DTA) and other analytical testing methods for the ore tourmaline ore properties, tourmaline type and structural characteristics, tourmaline The phase transition was studied and the type of tourmaline in Inner Mongolia was determined. The effects of tourmaline tourmaline and its tourmaline ceramsite on acid-base solution, deionized water and tap water were studied. The pH value and electrical conductivity were characterized and the mechanism analysis was carried out. The results show that the inner tourmaline has the effect of changing the pH of the aqueous solution. Value, and make it tend to 7 functions, can also be used repeatedly. It is proposed that the pH value of the solution is affected by the hydroxylation of the mineral surface and the electrode reaction of the tourmaline. The process and conditions of the magnetic separation of Inner Mongolia tourmaline are determined for the first time, so that the ore grade (tourmaline content) is 70% tourmaline. Purified to over 95%. Scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray diffraction analysis (XRD) were used to study the surface properties of tourmaline tourmaline. The principle of crystallization and solution chemistry was used to analyze the principle of floatability of tourmaline. . The electrification point method, the Yoon-Salman-Donnay equation (YSD) and the crystal chemistry method were used to calculate the zero point of the tourmaline, and compared with the zero point of the tourmaline measured by electrophoresis. The bond length of the M—O bond in the crystal structure of the stone, the electrostatic valence strength, the ionic bond component, the Coulomb force, the relative bonding strength, the polarity, and the bond valence. The analysis shows that some of the insoluble cations Fe~(2+), Mg~(2+), Al~(3+) on the surface of tourmaline are chemically adsorbed with oleate ions; on the other hand, tourmaline crystal surface and water When contact occurs, surface Na~+, Ca~(2+) cation dissociation, mineral surface hydroxylation, tourmaline surface negatively charged, and electrostatic adsorption with dodecylamine; The level is related to the concentration change of the collector ion-molecule association. In this paper, the suitable process conditions for preparing Inner Mongolia tourmaline powder by stirring mill were determined, and the particle size analysis and infrared emissivity and release negative ion concentration of tourmaline powder were tested and analyzed. The surface modification of Inner Mongolia tourmaline powder was studied by using stearic acid, silane coupling agent, silicone oil and titanate coupling agent as modifiers, and better modification effect was obtained. Temperature, time and modification were discussed. Factors such as the amount of agent added to the modification effect of tourmaline tourmaline were characterized by activation degree. Infrared spectroscopy (IR) showed that the modification mechanism was chemical adsorption. The mechanical properties of tourmaline/HDPE composites were studied, and they emit far infrared rays and release negative ions.
