Mining In Hong Kong
Mining in Hong Kong refers to mining activities in Hong Kong. Despite its small size, Hong Kong has a relatively large number of mineral deposits. Although some have been mined commercially, there are currently no commercial mining operations in Hong Kong.CEDDEconomic Geology - Minerals and Mining in Hong Kong/ref> Mines The four main mines in Hong Kong are the Lin Ma Hang Lead Mine (mainly galena for lead), the Needle Hill Tungsten Mine (Wolframite and Molybdenite), the Ma On Shan Iron Mine (magnetite for iron), and the West Brother Graphite Mine (graphite).

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Four Hills Of Kowloon
The Four Hills of Kowloon () are four hills that were historically the site of granite quarries in Kwun Tong District, New Kowloon, Hong Kong. History At the end of the 18th century, Hakka settled into the Cha Kwo Ling area, and quarrying became their main occupation. By that time, the villages of Cha Kwo Ling, Ngau Tau Kok, Sai Tso Wan and Lei Yue Mun were collectively called ''Si Shan'' (, "Four Hills").Civil Engineering and Development Department"Further Development of Tseung Kwan O.

Anderson Road, Hong Kong
Anderson Road is a road on the eastern border of the New Territories and New Kowloon in Hong Kong. It starts near the junction of Clear Water Bay Road and New Clear Water Bay Road, above Shun Lee Estate, then continues southeast to Tseng Lan Shue () and eastward through the hills above Sau Mau Ping, and finally ends at Po Lam Road () in Ma Yau Tong. Anderson Road Quarry To the east of the road is Tai Sheung Tok hill. From 1964, the hilltop was developed as a large quarry, Anderson Road Quarry (), highly visible from much of Kowloon and Hong Kong, which supplied construction aggregate to Hong Kong until July 2017, operated by the K.Wah Group, when it was one of only three quarries still operating in Hong Kong, along with those in Shek O and Lam Tei. The quarry site is on the ridge surrounding Kowloon, visible from much of urban Hong Kong, but was ultimately deemed to damage the beauty and the fungshui of Victoria Harbour.

Director Of Civil Engineering And Development
The Civil Engineering and Development Department (CEDD) is a department of the Hong Kong government that reports to the Development Bureau. Its major services include provision of land and infrastructure, port and marine services, geotechnical services and environment and sustainability services. Organisation The department has a headquarters, 2 functional offices (the Civil Engineering Office and the Geotechnical Engineering Office) and 5 regional development offices (the Sustainable Lantau Office, the East Development Office, the South Development Office, the West Development Office and the North Development Office). History The department was formed on 1 July 2004 through a merger of the Civil Engineering Department and the Territory Development Department. The CEDD formerly came under the (former) Environment, Transport and Works Bureau.

Tungsten
Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements barring carbon (which sublimes at normal pressure), melting at . It also has the highest boiling point, at . Its density is , comparable with that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten occurs in many ...

Silver
Silver is a chemical element with the Symbol (chemistry), symbol Ag (from the Latin ', derived from the Proto-Indo-European wikt:Reconstruction:Proto-Indo-European/h₂erǵ-, ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lantau Island
Lantau Island (also Lantao Island, Lan Tao) is the largest island in Hong Kong, located West of Hong Kong Island and the Kowloon Peninsula, and is part of the New Territories. Administratively, most of Lantau Island is part of the Islands District of Hong Kong. A small northeastern portion of the island is located in the Tsuen Wan District. Originally an island with fishing villages, it has been developed since the late 20th century with the construction of Tung Chung New Town on its north-western coast and the completion of several major infrastructure projects, including Lantau Link (1997), Hong Kong International Airport (1998), Hong Kong Disneyland (2005), Ngong Ping 360 (2006) and Penny's Bay Quarantine Centre (2020). Geography With a land mass of , it is the largest island in Hong Kong, almost twice the size of Hong Kong Island. Lantau Island primarily consists of mountainous terrain.
