Coal is the most important mineral, concentrated in the northern part of Taiwan Province Province, with an estimated reserve of 500 million tons and an exploitable output of about 200 million tons, but its coal quality is poor.

Coal is a combustible black or brownish-black sedimentary rock, which usually occurs in rock strata or veins called coal seams or coal seams.

Hard forms of coal can be considered metamorphic rocks, such as anthracite, because they are subsequently exposed to high temperature and high pressure. Coal is mainly composed of carbon and different amounts of other elements, mainly hydrogen, sulfur, oxygen and nitrogen.

2. golden

Gold deposits are distributed in Ruifang and Jinguashi areas in the northeast and along the east coast of the Central Mountain Range in the east.

Gold is a simple form of chemical element gold (chemical element symbol Au), which is a soft, golden yellow and corrosion-resistant precious metal. Gold is a rarer, more precious and more valuable metal.

Generally speaking, the gold in the world is in ounces. In ancient China, gold was measured in ounces, which was a very important metal. It is not only a special currency for reserve and investment, but also used in jewelry industry, electronics industry, modern communication, aerospace industry and other departments.

3. Sulfur

Distributed in Datun Mountain area at the northern end of Taiwan Province Province.

Sulfur is also called sulfur, colloidal sulfur and sulfur lump. Appearance is light yellow fragile crystal or powder, with special smell. The molecular weight is 32.06, the vapor pressure is 0. 13kPa, the flash point is 207℃, the melting point is 1 18℃, the boiling point is 444.6℃, and the relative density (water =1) is 2.0.

Sulfur is insoluble in water, slightly soluble in ethanol and ether, and easily soluble in carbon disulfide. As a flammable solid, sulfur is mainly used to make dyes, pesticides, matches, gunpowder, rubber, rayon and so on.

Sulfur is an important inorganic pesticide. This commodity is yellow solid or powder, which has obvious smell and can be volatilized. Sulfur aqueous suspension is slightly acidic, insoluble in water, and reacts with alkali to generate polysulfides.

When sulfur burns, it emits a blue flame, accompanied by combustion to produce sulfur dioxide gas. Sulfur is often processed into colloidal suspension for pest control in production, which is safe for people and livestock and is not easy to cause phytotoxicity to crops.

4. Copper

Copper mines are distributed in Ruifang and Jinguashi areas in the northeast and along the east coast of the Central Mountain Range in the east.

Copper is a transition element with chemical symbol Cu and atomic number 29. Pure copper is a kind of soft metal. When it is just cut, its surface is reddish-orange with metallic luster, and its simple substance is purplish red. Good ductility, high thermal conductivity and electrical conductivity.

Therefore, cables, electrical and electronic components are the most commonly used materials, and can also be used as building materials to form a variety of alloys. Copper alloys have excellent mechanical properties and low resistivity, among which bronze and brass are the most important. In addition, copper is also a durable metal, which can be recycled many times without damaging its mechanical properties.

5. Natural gas

Mainly distributed in the foothills and plains of western Taiwan.

Natural gas is mainly used as fuel to produce carbon black, chemicals and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry. Natural gas is mainly composed of gaseous low molecular hydrocarbons and non-hydrocarbon gases.

It is mainly composed of methane (85%) and a small amount of ethane (9%), propane (3%), nitrogen (2%) and butane (1%). Mainly used as fuel, but also used as raw materials for the manufacture of acetaldehyde, acetylene, ammonia, carbon black, ethanol, formaldehyde, hydrocarbon fuel, hydrogenated oil, methanol, nitric acid, synthetic gas, vinyl chloride and other chemicals.

Natural gas is compressed into liquid for storage and transportation. Coal miners, nitric acid producers, power plant workers, organic chemical synthesizers, gas users, refiners, etc. Have access to this product.
