Late Early Carboniferous (late Visean) to late Middle Permian (Capitanian) foraminifers have been recovered from limestone blocks and fragments contained in the Tsunemori Formation in Yamaguchi Prefecture, Southwest Japan, which is unconformably overlain by the Upper Triassic Mine Group. An analysis of the Tsunemori fauna shows an almost identical composition with that of the Akiyoshi ...

Coal is defined as a readily combustible rock containing more than 50% by weight of carbon. Coals other constituents include hydrogen, oxygen, nitrogen, ash, and sulfur. Some of the undesirable chemical constituents include chorine and sodium. In the process of transformation (coalification), peat is altered to lignite, lignite is altered to ...
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with ...

Japan - Japan - Resources and power: With few exceptions, Japan's mineral reserves are small, and the quality of those mined is often poor. Coal, iron ore, zinc, lead, copper, sulfur, gold, and silver are among the most abundant minerals (in relative terms), with lesser quantities of tungsten, chromite, and manganese. Japan also has large deposits of limestone.

The infrared optical constants, n and k, (n˜ = n − ik) of swelling and nonswelling coals, their respective char products, and limestone at room temperature have been obtained by a particle extinction technique using compressed KBr tablets.
Coal dust explosions in underground coal mines are pre vented by a generous application of rock dust (usually lime stone). If an explosion should occur, the rock dust disperses, mixes with the coal dust and prevents fl ame propagation by acting as a thermal inhibitor or heat sink. To investigate this process in more detail, a number of ex
A carbon sink is any reservoir, natural or otherwise, that accumulates and stores some carbon-containing chemical compound for an indefinite period and thereby lowers the concentration of carbon dioxide (CO 2) from the atmosphere.. Globally, the two most important carbon sinks are vegetation and the ocean. Public awareness of the significance of CO 2 sinks has grown since passage of the 1997 ...
Because coal undergoes physical and chemical changes as a result of increased heat, there is sometimes a misconception that coal is a metamorphic rock. Coal is a sedimentary rock. Coal is altered through biological and burial-thermal processes into different ranks. Many sedimentary rocks are also altered through burial-thermal processes ...
The mining sector was the smallest of Japan's industrial-based economy, accounting for 0.16% of GDP in 1999. The mineral-processing industry, however, was among the world's largest and most technologically advanced, accounting for 5.15% of Japan's GDP, and it played a key role in supplying steel, nonferrous metals, and chemicals for the country's world-class manufacturing sector, …

Limestone has many other uses. Powdered limestone is used as a filler in paper, paint, rubber, and plastics. Crushed limestone is used as a filter stone in on-site sewage disposal systems. Powdered limestone is also used as a sorbent (a substance that absorbs pollutants) at many coal-burning facilities. Limestone is not found everywhere.
