In RuneScape it is a lightweight blue metal stronger than steel. In World of Warcraft, mithril and truesilver both appear; truesilver is a rare spawn node in the same areas as mithril. Both can be mined as ore and smelted into a bar using the mining profession. Mithril also appears in the MMORPG Guild Wars 2 as a blueish-silver metal used in ...
Cattierite (Co S 2), vaesite (Ni S 2) and hauerite (Mn S 2), as well as sperrylite (Pt As 2) are similar in their structure and belong also to the pyrite group. Bravoite is a nickel-cobalt bearing variety of pyrite, with > 50% substitution of Ni 2+ for Fe 2+ within pyrite. Bravoite is not a formally recognised mineral, and is named after the ...
Cupellation is a refining process in metallurgy in which ores or alloyed metals are treated under very high temperatures and subjected to controlled operations to separate noble metals, like gold and silver, from base metals, like lead, copper, zinc, arsenic, antimony, or bismuth, present in the ore. [1][2][3] The process is based on the ...
Cinnabar (/ ˈsɪnəˌbɑːr /; from Ancient Greek κιννάβαρι (kinnábari)), [7] or cinnabarite (/ ˌsɪnəˈbɑːraɪt /), also known as mercurblende is the bright scarlet to brick-red form of mercury (II) sulfide (HgS). It is the most common source ore for refining elemental mercury and is the historic source for the brilliant red or ...
Adrenochrome is a chemical compound produced by the oxidation of adrenaline (epinephrine). It was the subject of limited research from the 1950s through to the 1970s as a potential cause of schizophrenia. While it has no current medical application, the semicarbazide derivative, carbazochrome, is a hemostatic medication.

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper ores consists of a series of physical, chemical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. [ 1 ]
The Miller process is an industrial-scale chemical procedure used to refine gold to a high degree of purity (99.5%). It was patented by Francis Bowyer Miller in 1867. This chemical process involves blowing chlorine gas through molten, but (slightly) impure, gold. Nearly all metal contaminants react to form chlorides but gold does not at these ...
