Abstract

PROBLEM TO BE SOLVED: To provide a method of effectively depositing metal and other inorganic matter dissolved in magma. SOLUTION: Water 30 is injected into magma 22 of a volcano 17 to generate high pressure water in which the magma 22 is dissolved within a cover 18 surrounding the magma 22 and deposit inorganic material dissolved in the high pressure water corresponding to the dissolution temperature. When the water 30 is injected into the magma 22, steam is generated from the surface of the magma 22. At this time, the higher the pressure of the water is, the more various kinds of the inorganic material dissolved in the magma 22 are dissolved in the high pressure water to turn it into steam and extracted from a stream takeoff port to deposit the target inorganic matter. And a high pressure steam extracting pipe may be inserted into the magma 22 of the volcano 17 to directly take out high pressure steam contained in the magma 22 and deposit inorganic material dissolved in this high pressure water corresponding to the dissolution temperature.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for precipitating an inorganic substance contained in an underground magma.

[0002]

2. Description of the Related Art As shown in FIG. 4, a general volcanic activity consists of a peridotite plate 13 and a basalt 14,
When submerged below the continental crust 10, the water carried from the sea 11 to the depth of the mantle 12 dissolves the surrounding mantle 12, and the melting temperature of the rock decreases due to the pressure drop due to the rise of mantle material due to mantle convection. To form the magma 22. This is the magma source 15, and the magma 22 generated here is stored in the magma chamber 16, transported to near the ground surface, and erupted to become the volcano 17.

[0003]

In a hot spring area or the like accompanying such a volcanic activity, when a hot spring blows out or only steam blows out, it is often observed that sulfur also blows out at the same time. This is the water layer 3 in the continental crust 10
When 4 is heated by the magma 22 and blown out to the ground, the water vapor and hot water fall to 100 degrees Celsius or less, and the inorganic substances dissolved in the water at 100 degrees Celsius or less are deposited on the ground. However, it has been desired to take out a metal dissolved in water at a high temperature of several hundred degrees or an intended inorganic substance dissolved in the magma 22.

An object of the present invention is to provide a method for efficiently depositing metals and other inorganic substances dissolved in the magma 22.

[0005]

According to the present invention, water is injected into a magma 22 of a volcano 17 to generate high-pressure water in which the magma 22 is dissolved in a cover 18 surrounding the magma 22, The high-pressure steam extraction pipe 23 is inserted into the magma 22 to directly take out the high-pressure steam contained in the magma 22, and the inorganic substances dissolved in the high-pressure water are deposited according to the melting temperature. This is a method for depositing an inorganic substance.

[0006] When water 30 is injected into the magma 22 of the crater 21 from the water inlet 19, water vapor is generated from the surface of the magma 22. At this time, as the pressure inside the cover 18 becomes higher, various kinds of metals and other inorganic substances dissolved in the magma 22 are dissolved in the high-pressure water to form steam, and the steam is taken from the steam outlets 20a to 20g. The steam at the temperature is extracted, and the desired inorganic substance is precipitated.

The magma 22 is provided with a high-pressure steam extraction tube 23.
And supplied from the water layer 34 or the like, and the magma 22
The high-pressure steam contained therein is directly taken out, and the desired inorganic substance is deposited.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Ultra-high pressure water of 700 degrees Celsius above several hundred atmospheres dissolves all metals and other inorganic substances. According to the present invention, based on this idea, the magma 22 inside the continental crust 10 is led to the surface of the earth, and an intended inorganic substance is extracted from the inorganic substances dissolved in the magma 22.

In FIG. 1, a magma 22 exposed at a crater 21 of a volcano 17 is covered with a cover 18 so as to hermetically close it.
Water 30 is injected from the water inlet 19 into this. Then, the magma 22 is heated to generate steam. Water whose pressure inside the cover 18 is as high as possible is taken out from the steam outlet 20. Then, water containing a large amount of the noble metal in which the magma 22 is dissolved is taken out, so that the target metal and other inorganic substances are precipitated from the high-temperature water.

More specifically, as shown in FIG. 2, the crater 21 of the volcano 17 is covered with a cover 18 and the cover 18 is closed.
Is provided with a water inlet 19 for injecting water 30, and is connected to a high-pressure steam extraction pipe 23 for extracting high-pressure water. The cover 18 and the high-pressure steam extraction pipe 23 are provided with steam outlets 20a to 20g at predetermined intervals so as to take out water at a predetermined temperature with a decrease in pressure. In order to more accurately control the temperature of the water, the pressure reducing valve 35 may be arranged at an appropriate position. When the water layer 34 exists inside the continental crust 10, the water layer 3
Holes 33 up to 4 may be formed, and water 30 may be injected instead of or together with water inlet 19.

In such a configuration, when water 30 is injected into the magma 22 of the crater 21 from the water inlet 19, the magma 2
Water vapor is generated from the surface of No. 2. At this time, as the pressure inside the cover 18 becomes higher, various kinds of metals and other inorganic substances dissolved in the magma 22 are dissolved in the high-pressure water to form steam, and the steam is taken from the steam outlets 20a to 20g. The steam at the temperature is extracted, and the desired inorganic substance is precipitated.

That is, the steam outlet 2 close to the cover 18
From 0a, a substance containing more noble metal is deposited, and as the distance increases, a substance having a lower melting temperature is deposited.

FIG. 3 shows a high pressure steam extraction pipe 2
3 and supplied from the water layer 34 or the like.
2 shows a method for directly extracting high-pressure water vapor contained in the fuel cell 2. In this case, a portion inserted into the magma 22 may be melted by the magma 22, and it is necessary to take measures to prevent the melting.

For example, the high-pressure steam extraction tube 23 is made of a heat-resistant ceramic or the like. Nevertheless, there is a possibility that the high-pressure steam extraction pipe 23 may be melted.
Therefore, the outer periphery of the high-pressure steam extraction pipe 23 is surrounded by a double cooling vessel 26. The cooling container 26 has heat resistance and is made of a porous material. Then, water 30 is injected from the cooling water injection port 27 of the cooling container 26. Then, the water 30 is ejected as steam from the cooling vessel 26 to the outside, and the heat of vaporization at that time forms a cooled temperature gradient layer 28 of the magma 22 on the outer periphery of the cooling vessel 26. This prevents the high-pressure steam extraction tube 23 from being dissolved, and efficiently extracts high-pressure steam from the lower end opening of the high-pressure steam extraction tube 23.

At this time, it is necessary to always supply the water 30 from the hole 33 in order to prevent the water in the water layer 34 from running out.
