Prefecture-level City
A prefecture-level city () or prefectural city is an administrative division of the People's Republic of China (PRC), ranking below a province and above a county in China's administrative structure. During the Republican era, many of China's prefectural cities were designated as counties as the country's second level division below a province. From 1949 to 1983, the official term was a province-administrated city (Chinese: 省辖市). Prefectural level cities form the second level of the administrative structure (alongside prefectures, leagues and autonomous prefectures). Administrative chiefs (mayors) of prefectural level cities generally have the same rank as a division chief () of a national ministry. Since the 1980s, most former prefectures have been renamed into prefectural level cities. A prefectural level city is a "city" () and "prefecture" () that have been merged into one consolidated and unified jurisdiction. As such it is simultaneously a city, which is a munici ...

Telephone Numbers In China
Telephone numbers in China are organized according to the Chinese Telephone Code Plan. The numerical formats of landlines and mobile phones are different: landlines have area codes, whereas mobile phones do not. In major cities, landline numbers consist of a two-digit area code followed by an eight-digit inner number. In other places, landline numbers consist of a three-digit area code followed by a seven- or eight-digit internal number. The numbers of mobile phones consist of eleven digits. When one landline is used to dial another landline within the same area, it is not necessary to specify the area code. The target number must be prepended between different regions with the trunk prefix, which is 0. Calling a mobile phone from a landline requires the addition of the "0" in front of the mobile phone number if they are not in the same area. Mobile to landline calls requires the "0" and the area code if the landline is not within the same place. Mobile to mobile calls does not ...

District (PRC)
The term ''district'', in the context of China, is used to refer to several unrelated political divisions in both ancient and modern China. In the modern context, district (), formally city-governed district, city-controlled district, or municipal district (), are subdivisions of a municipality or a prefecture-level city. The rank of a district derives from the rank of its city. Districts of a municipality are prefecture-level; districts of a sub-provincial city are sub-prefecture-level; and districts of a prefecture-level city are county-level. The term was also formerly used to refer to obsolete county-controlled districts (also known as district public office). However, if the word ''district'' is encountered in the context of ancient Chinese history, then it is a translation for ''xian'', another type of administrative division in China. Before the 1980s, cities in China were administrative divisions containing mostly urban, built-up areas, with very little farmland ...

Malachite
Malachite is a copper carbonate hydroxide mineral, with the formula Cu2CO3(OH)2. This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation. Individual crystals are rare, but occur as slender to acicular prisms. Pseudomorphs after more tabular or blocky azurite crystals also occur. Etymology and history The stone's name derives (via la, molochītis, frm, melochite, and Middle English ''melochites'') from Greek Μολοχίτης λίθος ''molochites lithos'', "mallow-green stone", from μολόχη ''molochē'', variant of μαλάχη ''malāchē'', "mallow". The mineral was given this name due to its resemblance to the leaves of the mallow plant. Malachite was mined from deposits near the Isthmus of Suez and the Sinai as early as 4000 BCE. It wa ...

Chrysocolla
Chrysocolla ( ) is a hydrated copper phyllosilicate mineral and mineraloid with formula (x<1) or . The structure of the mineral has been questioned, as a 2006 spectrographic study suggest material identified as chrysocolla may be a mixture of the copper hydroxide and . History The name comes from the χρυσός (''chrysos'') and κολλα (''kolla''), "gold" and "glue," in allusion to the name of the material used to solder |
Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Copper Mine
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using mineral flotation. The concentrate is typically sold to distant smelters, although some large mines have smelters located nearby. Such colocation of mines and smelters was more typical in the 19th and early 20th centuries, when smaller smelters could be economic. The sulfide concentrates are typically smelted in such furnaces as the Outokumpu or Inco f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A-Hmao Language
The A-Hmao language, also known as Large Flowery Miao () or Northeast Yunnan Miao (), is a Hmongic language spoken in China. It is the language the Pollard script was designed for, and displays extensive tone sandhi. There is a high degree of literacy in Pollard among the older generation. The standard written language, both in Pollard and in Latin script, is that of () village in Weining County. Classification The A-Hmao language is a branch of the West Hmongic languages, also known as Chuanqiandian Miao () and Western Miao, which is a major branch of the Hmongic languages of China and Southeast Asia.
