Product Description:

In the last 15 years Minermet Group has opened up a new Division for Anthracite, Coal and Coke which is expanding very much, for markets in Europe, Russia, Middle East, Pakistan, India, Vietnam,  Australia and Indonesia.


Coal (from the Old English term col, which has meant "mineral of fossilized carbon" since the 13th century)is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen.

Throughout history, coal has been used as an energy resource, primarily burned for the production of electricity and/or heat, and is also used for industrial purposes, such as refining metals. A fossil fuel, coal forms when dead plant matter is converted into peat, which in turn is converted into lignite, then sub-bituminous coal, after that bituminous coal, and lastly anthracite. This involves biological and geological processes that take place over a long period. The Energy Information Administration estimates coal reserves at 948×109 short tons (860 Gt).One estimate for resources is 18 000 Gt.

Coal is the largest source of energy for the generation of electricity worldwide, as well as one of the largest worldwide anthropogenic sources of carbon dioxide releases. In 1999, world gross carbon dioxide emissions from coal usage were 8,666 million tonnes of carbon dioxide.In 2011, world gross emissions from coal usage were 14,416 million tonnes.Coal-fired electric power generation emits around 2,000 pounds of carbon dioxide for every megawatt-hour generated, which is almost double the approximately 1100 pounds of carbon dioxide released by a natural gas-fired electric plant per megawatt-hour generated. Because of this higher carbon efficiency of natural gas generation, as the market in the United States has changed to reduce coal and increase natural gas generation, carbon dioxide emissions have fallen. Those measured in the first quarter of 2012 were the lowest of any recorded for the first quarter of any year since 1992.In 2013, the head of the UN climate agency advised that most of the world's coal reserves should be left in the ground to avoid catastrophic global warming.

Coal is extracted from the ground by coal mining, either underground by shaft mining, or at ground level by open pit mining extraction. Since 1983 the world top coal producer has been China.In 2011 China produced 3,520 million tonnes of coal – 49.5% of 7,695 million tonnes world coal production. In 2011 other large producers were United States (993 million tonnes), India (589), European Union (576) and Australia (416).[9] In 2010 the largest exporters were Australia with 328 million tonnes (27.1% of world coal export) and Indonesia with 316 million tonnes (26.1%),while the largest importers were Japan with 207 million tonnes (17.5% of world coal import), China with 195 million tonnes (16.6%) and South Korea with 126 million tonnes (10.7%).

Q:What is the name of the coal Juban and Hang Hau price?
Juban: refers to the train loaded coal, which will be issued before, all expenses except freight train. It includes coal pit prices, taxes and fees, car freight, a number of tax on the train platform, railway planning fees, etc..
Q:What is the specific coal chemical
The process of converting coal into gas, liquid and solid fuels and chemicals from coal. Mainly including coal gasification, liquefaction, distillation, as well as tar processing and calcium carbide acetylene chemical
Q:Charcoal sales channels? Where should I sell it?! That's the fastest Market
A charcoal mechanism widely applies to: 1, metallurgy (iron reducing agent, electrode, aluminum ingot thermal insulating agent; 2), chemical (for the production of carbon disulfide, calcium carbide, carbon tetrachloride, etc.); 3 buildings (concrete special fillers, insulation materials, refractory materials, etc.); 4 (improved rural gardening soil, water and soil conservation and smoked fried tea etc.)
Q:Soft, hard charcoal, what is the difference?
Charcoal is mostly made of willow twigs baked from coarse and fine, soft and hard, and because of the picture effectThe painting with a soft start with charcoal and proofing, because of its easy to erase, repeated correction, not to hurt the paper, detail modificationWhen using the hard charcoal. A paint can be coated, wipe, wipe, can also do a line or block surface treatment, can make a very abundance
Q:What is the use of power coal
With the coal category, mainly lignite, long flame coal, non caking coal, lean coal and a small amount of anthracite. From the commodity coal, the main washing mixed coal, washed coal, coal, coal, etc.. The poor quality coal mainly refers to the low ash value (less than 40%) which is unfavorable to the operation of the boiler (less than 15). Bituminous coal of 73 MJ / kg, anthracite with low volatile content (less than 10%), lignite with high moisture content and high sulfur content (more than 2%), etc..
Q:Add sugar to charcoal charcoal is to do hair.. what!?
Put into the refrigerator after use, you can use half a month!!!After two weeks of my experienceI think this soy milk in addition to hair dew really God ah!!!!!I was interrupted with the 'The time spent 3 consecutive days to go to school, so was forced to disable... But first painted on the effects of hair grows slowly, and the finer than before...Second weeks because of the relationship between the school I used only one day..(my first week and the second week is shaved, with tweezers to pluck the relatively dark fur coat.)So after the experiment, indicating that this soy milk in addition to hair is to be used continuously!!!At least two times a day to be painted, at least for a period of 3 days to have effect, I believeIf I persevere, will be able to get the fine drizzle did not look carefully, see!!!!
Q:What raw materials to produce charcoal
Activated carbon: activated carbon can be said to be deep processing of charcoal is mainly produced in southern China, Fujian and Zhejiang area, he is to use charcoal, zinc chloride, phosphoric acid, potassium hydroxide and dolomite, chemical activation, rinsing, drying and grinding processing, the production process of water pollution is serious, production is restricted by the state.Mechanism of carbon: sawdust as raw material, the process is mainly the sawdust by machine high temperature, high pressure molding, and then into the carbonization furnace carbonization. The whole production process does not need to add any additives, belong to the category of environmental protection products. In the market, the main hexagon center is empty and there are two shapes in the center of the square. The mechanism of carbon as a traditional charcoal (traditional charcoal: trees as raw material, sintering, is a kind of destruction of resources industry has now been forbidden by the state) alternative products, it has high calorific value, burning a long time, do not smoke, do not send explosion, environmental protection and many other advantages.
Q:What is the difference between white and black peat
The "black peat" is more dense, but it is not suitable for the production of humic acid and humic acid fertilizer.
Q:Activated carbon can really dehumidification
Throw into the water, will be a lot of blisters, like a sponge absorbent
Q:What is the thermal stability of coal
(2) 6~13 mm 6~13 mm. Determination of coal level of coal 500 cubic centimeters, said its weight in preheating to heating muffle furnace 850 DEG C for 90 minutes, then remove the weighing and screening. The "6" mm, 3 mm,% total weight and number of char < 1 mm as the stability index KP6, KP3 and KP1 index show that the greater the value, the poor thermal stability.Thermal stability classification of coalGrade thermal stability KP6,%Good thermal stability is less than or equal to 30Thermal stability medium 30~45Poor thermal stability 45
