Carbon

Carbon (from Latin carbo 'coal') is a chemical element; it has symbol C and atomic number 6. It is nonmetallic and tetravalent—meaning that its atoms are able to form up to four covalent bonds due to its valence shell exhibiting 4 electrons. It belongs to group 14 of the periodic table. Carbon makes up about 0.025 percent of Earth's crust.

Gold Ore – Minecraft Wiki

Gold ore can generate in the Overworld in the form of ore features. Gold ore attempts to generate in two batches. The first batch generates 4 times per chunk in blobs of 0—13 blocks, from levels -64 to 32. It is most likely to be found around layer -16, becoming less common toward either end of the range.

Metallurgical testwork: Gold processing options, physical ore

Thus as the gold is dissolved by the cyanide it is absorbed by the preg-robber, and solution assay monitoring will show a low or barren gold tenor. In these cases activated carbon is added upfront (carbon-in-leach), which should preferentially adsorb the gold as it is dissolved from the ore, and thus enable a determination of gold recovery to ...
