Mining - Wikipedia
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Supergene (geology) - Wikipedia
In ore deposit geology, supergene processes or enrichment are those that occur relatively near the surface as opposed to deep hypogene processes. Supergene processes include the predominance of meteoric water circulation with concomitant oxidation and stone weathering.The descending meteoric waters oxidize the primary sulfide ore minerals and redistribute the metallic ore elements.

Oxidation in the presence of water vapor or steam. Material exposed to pure steam will also undergo oxidation because oxygen is present in the form of H 2 O. As a rule, steam produces faster oxidation than air. Oxide layers formed in steam are more iron-rich and …

Peter Russell The oxidized zone of ore deposits has fascinated me for many years because of the process of their formation and the resulting reddish brown rocks. The colourful rocks are a signal to prospectors that economic ore cannot be far away. Stories abound of rusty outcrops luring prospectors across the southwestern U.S.A. to grub in the rocks to find a fortune, or a
Arsenic oxidation and immobilization in acid mine …
1. Introduction. Acid mine drainage (AMD) causes a serious environmental pollution around the world because of the low pH (i.e., <3) and elevated concentrations of toxic trace metals (Arnold et al., 2011; Cheng et al., 2009; Migaszewski et al., 2019).Arsenic (As) is one of the most toxic metalloids in AMD and its concentration ranges from <1 to 850,000 μg/L (Cheng et al., 2009).

Its structure of many small parallel channels presents high catalytic contact area to the exhaust gases. As the hot gases flow through the channels and contact the catalyst, several exhaust pollutants are converted into harmless substances. The following reactions occur in the oxidation catalyst:
