 「地球」と「環境」

私たちの暮らしと金属

While oil, coal and some other resources are mainly used to produce energy, metals are used as materials to make various products. Taking advantage of their features--reflective when polished, transforming depending on temperature, becoming new material when melted and combined--metals are used in diverse areas. Actually, large and small products from the bodies of planes, ships, trains and cars, as well as small products, including knives, forks, nails and coins are all made of metals.

日本の鉱業

Under our current global economy and with present technology, we are certain to run out of resources in the future. Since these resources are necessary for producing goods and energy, they are vital to our future. If we run out of resources, we will no longer be able to produce the products and electricity required to keep our airplanes, trains and cars running.   イラスト

鉄と非鉄金属

More than 90% of the metals produced in Japan are iron and steel; the rest are nonferrous metals. Despite the small amount produced, nonferrous metals are indispensable for certain industries because of their unique qualities. Nonferrous metals include base metals such as copper, zinc, lea, and aluminum, and precious metals such as gold, silver, and platinum. Metals with small reserves or those that are abundant but economically and technically difficult to extract are specifically called rare metals. Base metals are used for coating and in various cables while rare metals are essential in high-tech industries and areas such as electronics.   世界の生産量に対する日本の使用量(2006年)

日本の産業とレアメタル

Rare metals are indispensable for Japan's main industry of manufacturing high-performance products. Personal computers, cell phones, electric/electronic devices, home appliances such as televisions and air conditioners, as well as carbide tools are all use rare metals. However, like other metals, rare metals are produced in a limited number of countries, and Japan imports most of the metals it uses.   主要レアメタルの輸入動向
