Definitions

  • the present invention relates to a method of manufacturing germanium-containing solution from yellow soil distributed on the earth's surface, and more particularly to a method of manufacturing germanium-containing solution by heating yellow soil formed in a clod of earth to red heat and dipping the clod of the yellow soil in water, so that oxidized organic germanium-containing solution can be obtained with high efficiency, and the germanium which acts advantageously on the human body can be used environmental-friendly and economically.
  • Germanium is a carbon group element belonging to 4B of Periodic Table, with its atomic symbol Ge, atomic number 32, melting point 958.5°C, and boiling point 2,700 0 C. It is a semi-metallic element distributed widely and thinly under the earth's crust and it is found in germanite, argyrodite, and some zinc ores. It is also present in coal and is known to be present in certain plants. Germanium is stable in the air, but tends to be oxidized in a heated state to red hot.
  • germanium chloride was obtained as a by-product in the process of refining sulfide minerals. That is, ores containing germanium were burned to make germanium oxide, which was then sintered by adding coal and salt to produce germanium and cadmium as volatile parts. These volatile parts were absorbed by sulfuric acid and cadmium was removed by using zinc powder. Then, the resulting product was dried and calcinated, and then distilled with hydrochloric acid to finally produce germanium chloride.
  • germanium was obtained as chloride compounds in a powder form. Therefore, in order to apply to the human body or for other uses, they should be processed further, and thus it was not economical and it was inevitable that their applications should be limited. Further, the manufacturing processes up to obtaining the germanium chloride were not simple, and should be proceeded with considerable care since various chemicals which could be harmful were used in the procedures.
  • Korean Patent No. 302277 (Application No. 10-1999-31010) issued on July 2, 2001 disclosed a method of manufacturing germanium-containing solution from natural germanium ores.
  • natural raw ores containing 0.36 to 1.05 germanium were pulverized to 200-250 meshes, dried at 100-110 0 C for 1-2 hours, cooled in the air, and sintered at 1050-1100 0 C for 4-5 hours. After the sintered product was cooled in the air, distilled water was added to reach the concentration of 0.5-1.0 kg/1. Then, the solution was stirred for 30-40 minutes and filtered to give the germanium-containing solution. Disclosure of Invention Technical Problem
  • germanium raw ores had to be pulverized and sintered in high tem ⁇ peratures above 1,000 0 C, labor costs and manufacturing costs could be considerably expensive.
  • the present invention uses yellow soil including the earth from a fireplace, which is commonly available from the earth's surface, as raw materials, instead of the natural germanium ores.
  • the present invention does not require the germanium ores to be pulverized and sintered in such high temperatures above 1,000 0 C, which demands con ⁇ siderable labor costs and manufacturing costs, but does extract maximum oxidized organic germanium from the yellow soil and the earth from a fireplace by heating the soil in a suitable temperature range of 750 to 930 0 C and by heating the soil formed in a clod of earth to red heat.
  • a method of manufacturing germanium-containing solution from yellow soil comprises: forming clods by clumping the yellow soil including earth from a fireplace; drying the clods of the soil at room tem ⁇ peratures for more than 24 hours or by heating them; heating the clods of the soil to red heat at 750 to 930 0 C for 30 to 60 minutes; dipping the red-heated clods of the soil in water to extract oxidized germanium in a solution; and filtering the solution including the clods of the soil to produce a germanium-containing solution.
  • the present invention provides a method of manufacturing germanium- containing solution which is more economical than the above-mentioned conventional methods in terms of manufacturing processes and expenses. Best Mode for Carrying Out the Invention
  • clods are formed by clumping the yellow soil including the earth from a fireplace. Then, the clods of the soil are dried at room temperatures for more than 24 hours or dried by heating, and heated at 750 to 930 0 C for 30 to 60 minutes. The heated clods of the soil are then dipped in water to extract oxidized germanium, and filtered to produce a germanium- containing solution.
  • the residue After the germanium-containing solution is separated out by filtering, the residue includes particulates and the yellow soil in the form of clods.
  • the residue is stirred to be in the form of particulates, and it may be used as a raw material for cosmetics to supply oxygen to the skin. It may also be used as a moisturizing agent for the skin and as a functional material added to various products such as foods and health foods.
  • concentration of germanium in the germanium- containing solution can be adjusted by varying the amount of the red-heated clods of the soil to be dipped in water, according to usages of interest.
  • the organic germanium obtained according to the present invention has no harmful effect on the human body since it is completely discharged through urine within 20 to 30 hours.
  • the present invention is characterized in that, instead of the natural germanium ores used in the conventional method, the yellow soil including the earth from a fireplace which is commonly available from the earth's surface is used as raw materials of the germanium-containing solution.
  • the earth from the fireplace means yellow soil obtained by repeatedly heating the soil in high temperatures and cooling it in the fireplace. According to a published literature, the earth from the fireplace is an effective treatment of vertigoes, hematemesis and paralysis.
  • the yellow soil including the earth from the fireplace is used in the present invention in the form of a clod with the size of a chicken egg. If the yellow soil is not clumped in the clod, but is used as it is, it is practically very difficult to adjust the tem ⁇ peratures for heating the soil to red heat. That is, since individual soil particles are heated abruptly and cooled so quickly, the efficiency of the manufacturing process can deteriorate, thus reducing the efficiency of extracting germanium from the yellow soil. Therefore, by clumping the yellow soil in the present invention, it becomes easy to heat the yellow soil to red heat and becomes smooth to proceed with the entire processes, thus increasing the efficiency of extracting germanium from the yellow soil.
  • the process of clumping the yellow soil does not require any adhesives. This is because the yellow soil clumps itself by its binding property without adhesives.
  • the dried clods of the soil are placed in a furnace and heated to red heat at 750 to 930 0 C for 30 to 60 minutes.
  • a medium for heating to red heat may be charcoal, coal, electricity, gas, etc.
  • a suitable furnace such as charcoal kiln, fine charcoal furnace, electric furnace, gas furnace, etc. may be used.
  • the lower heating temperature of 750 0 C was chosen because the clods of the soil begin to make red-hot at the lowest 750 0 C and the oxidation of germanium initiates at 750 0 C. Further, the higher heating temperature of 930 0 C was chosen because germanium melts and becomes an ingot above the temperature 958.5°C (melting point) and it cannot be oxidized.
  • the germanium-containing solution may be used as an activating material or auxiliary material for various products depending on its adaptability to a specific field and also be used as drinking water.
  • Mode for the Invention
  • germanium-containing solution of good quality can be manufactured inexpensively and in an environment-friendly manner, without using expensive equipments and chemical materials.
  • the present invention uses the yellow soil including the earth from the fireplace, which is commonly available from the earth's surface, as raw materials of germanium-containing solution, instead of the natural germanium ores, it is economical in terms of manufacturing processes and expenses.
