PURPOSE : A method for manufacturing magnetic minerals is provided, thereby improving culture efficiency of microorganisms when the magnetic minerals are used. CONSTITUTION : A method for manufacturing magnetic minerals comprises the steps of : mixing ore-forming mineral powder such as rhyolite or dacite pumice stone, amphibole, olivine, biotite and volcanic ash soils with far infrared and negative ion irradiating mineral powder such as phyllite, pegmatite, quartz porphyry, tourmaline and jade; inserting organic acid such as citric acid, tartaric acid, succinic acid and fulvic acid, and chloric acid and sulfuric acid into the mixture to regulate pH value of the mixture to 1.5 to 2.5; stirring the mixture to prepare a gel type chelate mineral complex; adding magnetite and ferrite powder into the complex; adding bentonite as an inorganic binder and sodium alginate, chitosan resin, cellulose resin and starch as organic binder into the complex to prepare dough; processing pellets or pills using the dough; drying the pellets or pills at room temperature with hot wind, and magnetizing them. |
