Udon North Mine
The Udon North Mine is a large potash mine in northern Thailand in Udon Thani Province. The project is approximately 15-20 kilometres southeast of the city of Udon Thani. The project area, including Udon South Mine, covers five sub-districts including Non Sung, Nong Phai, and Nong Khon Kwang of Mueang Udon Thani District together with Huai Sam Phat and Na Muang Sub-districts of Prachaksinlapakhom District. Northeast Thailand is believed to contain the world's third-largest—after Canada and Russia—unexploited potash reserves. Operations Mining operations occupy an area of about 26,446 rai or 42.3 km2 which consists of the processing plant area of 1,250 rai (2 km2) and an underground mine. The mine is an underground room and pillar mine projected to reach depths of 350–380 metres. Udon North and South represent one of the largest potash reserves in Thailand, having estimated reserves of 665 million tonnes of ore grading 16 percent potassium chloride extracted from ...

Thailand
Thailand ( ), historically known as Siam () and officially the Kingdom of Thailand, is a country in Southeast Asia, located at the centre of the Indochinese Peninsula, spanning , with a population of almost 70 million. The country is bordered to the north by Myanmar and Laos, to the east by Laos and Cambodia, to the south by the Gulf of Thailand and Malaysia, and to the west by the Andaman Sea and the extremity of Myanmar. Thailand also shares maritime borders with Vietnam to the southeast, and Indonesia and India to the southwest. Bangkok is the nation's capital and largest city. Tai peoples migrated from southwestern China to mainland Southeast Asia from the 11th century. Indianised kingdoms such as the Mon, Khmer Empire and Malay states ruled the region, competing with Thai states such as the Kingdoms of Ngoenyang, Sukhothai, Lan Na and Ayutthaya, which also rivalled each other. European contact began in 1511 with a Portuguese diplomatic mission to Ayutthaya, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prachaksinlapakhom District
Prachaksinlapakhom ( th, ประจักษ์ศิลปาคม) is a district (''amphoe'') in central Udon Thani province, northeastern Thailand. Geography Neighboring districts are (from the north clockwise) Nong Han, Ku Kaeo, Kumphawapi, and Mueang Udon Thani. History The minor district (''king amphoe'') was established on 1 June 1997 by splitting it from Kumphawapi district. The creation became effective on 1 July 1997. On 15 May 2007, all 81 minor districts were upgraded to full districts. With publication in the ''Royal Gazette'' on 24 August, the upgrade became official. Administration Central administration Prachaksinlapakhom is divided into three sub-districts (''tambons''), which are further subdivided into 41 administrative villages (''muban Muban ( th, หมู่บ้าน; , ) is the lowest administrative sub-division of Thailand.

Rai (unit)
A ''rai'' ( th, ไร่, ) is a unit of area equal to 1,600 square metres (16 ares, 0.16 hectares, 0.3954 acres), and is used in measuring land area for a cadastre or cadastral map. Its current size is precisely derived from the metre, but is neither part of nor recognized by the modern metric system, the International System (SI). The rai is defined as 1 square ''sen'' or (40 m × 40 m). It can be divided in four ''ngaan'' or 400 square '' wa''. It is commonly used in Thailand. Although recognized by the SI, its use is not encouraged. The word ''rai'' also means plantation.

Room And Pillar
Room and pillar or pillar and stall is a variant of breast stoping. It is a mining system in which the mined material is extracted across a horizontal plane, creating horizontal arrays of rooms and pillars. To do this, "rooms" of ore are dug out while "pillars" of untouched material are left to support the roof overburden. Calculating the size, shape, and position of pillars is a complicated procedure, and is an area of active research. The technique is usually used for relatively flat-lying deposits, such as those that follow a particular stratum. Room and pillar mining can be advantageous because it reduces the risk of surface subsidence compared to other underground mining techniques. It is also advantageous because it can be mechanized, and is relatively simple. However, because significant portions of ore may have to be left behind, recovery and profits can be low. Room and pillar mining was one of the earliest methods used, although with significantly more man-power. The room ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potassium Chloride
Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt-like taste. Potassium chloride can be obtained from ancient dried lake deposits. KCl is used as a fertilizer, in medicine, in scientific applications, domestic water softeners (as a substitute for sodium chloride salt), and in food processing, where it may be known as E number additive E508. It occurs naturally as the mineral sylvite, and in combination with sodium chloride as sylvinite. Uses Fertilizer The majority of the potassium chloride produced is used for making fertilizer, called potash, since the growth of many plants is limited by potassium availability. Potassium chloride sold as fertilizer is known as muriate of potash (MOP). The vast majority of potash fertilizer worldwide is sold as MOP. Medical use Potassium is vital ...

Sylvite
Sylvite, or sylvine, is potassium chloride (KCl) in natural mineral form. It forms crystals in the isometric system very similar to normal rock salt, halite ( NaCl). The two are, in fact, isomorphous. Sylvite is colorless to white with shades of yellow and red due to inclusions. It has a Mohs hardness of 2.5 and a specific gravity of 1.99. It has a refractive index of 1.4903. Sylvite has a salty taste with a distinct bitterness. Sylvite is one of the last evaporite minerals to precipitate out of solution. As such, it is only found in very dry saline areas. Its principal use is as a potassium fertilizer. Sylvite is found in many evaporite deposits worldwide. Massive bedded deposits occur in New Mexico and western Texas, and in Utah in the US, but the largest world source is in Saskatchewan, Canada. The vast deposits in Saskatchewan, Canada were formed by the evaporation of a Devonian seaway. Sylvite is the official mineral of Saskatchewan. Sylvite was first described in 1832 a ...

Thai Baht
The baht (; th, บาท, ; currency sign, sign: ฿; ISO 4217, code: THB) is the official currency of Thailand. It is divided into 100 ''satang'' (, ). The issuance of currency is the responsibility of the Bank of Thailand. Society for Worldwide Interbank Financial Telecommunication, SWIFT ranked the Thai baht as the 10th-most-frequently used world payment currency as of January 2019. History The Thai baht, like the Pound (currency), pound, originated from a traditional unit of mass. Its currency value was originally expressed as that of silver of corresponding weight (now defined as 15 grams), and was in use probably as early as the Sukhothai Kingdom, Sukhothai period in the form of bullet coins known in Thai as ''phot duang''. These were pieces of solid silver cast to various weights corresponding to a Thai units of measurement, traditional system of units related by simple fractions and multiples, one of which is the ''baht (unit), baht''. These are listed in the follo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tonne
The tonne ( or ; symbol: t) is a unit of mass equal to 1000 kilograms. It is a non-SI unit accepted for use with SI. It is also referred to as a metric ton to distinguish it from the non-metric units of the short ton ( United States customary units), and the long ton ( British imperial units). It is equivalent to approximately 2204.6 pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram (symbol: Mg), a less common way to express the same mass. Symbol and abbreviations The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879.Table 6 . BIPM. Retrieved on 2011-07-10. Its use is also official for the metric ton in the United States, having been adopted by the United States |
