peat. Peat properties reflect the peat-forming environment, development process and the types of peat-forming plants. Peat consists of organic matter, mineral matter and water. Under natural conditions, the content of water in peat exceeds 80% and content of gases content is about 6%. In dry peat, the organic matter content can reach 50%.

Peat (/ p iː t /), also known as turf (/ t ɜːr f /), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem is the most efficient carbon sink on the planet, because peatland plants capture CO 2 naturally released from the peat, maintaining an equilibrium.
Based on our data from Lapphyttan and from Kalven, mining and ore processing in the Norberg mining district were established in the region during the period from the late 12th to late 13th centuries. Our data from the mire record at Lapphyttan support the earliest suggested dates for the establishment of the furnace at that site.
In 2010, world iron ore pellet production was 388 Mt. It could be argued that the current pellet production process has been enabled by the use of binders – practical experience has shown that it would be nearly impossible to agglomerate iron ore using rotary drums and discs without using a binder.

Eris is the most massive and second-largest (by volume) dwarf planet (and plutoid) known in the Solar System. Eris was discovered in January 2005 by a Palomar Observatory-based team led by Mike Brown, and its discovery was verified later that year.
The majority of Earth's iron, however, exists in iron ore. Mined right out of the ground, raw ore is mix of ore proper and loose earth called gangue. The ore proper can usually be separated by crushing the raw ore and simply washing away the lighter soil.
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air — a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.
gold ore. The dissolved gold in the form of the complex now needs to be separated out and recovered. This can be done by a process called absorption. Absorption is when gaseous or dissolved species attach to a solid surface. A substance called activated carbon is used to absorb the gold. Activated carbon is formed from wood, peat, coal, etc.
