Ore Deposits Formed By Oxidation And Supergene Enrichment

Ore Deposits Formed by Oxidation and Supergene Enrichment When ore deposits are exposed to the oxidation zone they are weathered and altered with the country rocks. The surface waters oxidize many ore minerals and yield solvents that dissolve other minerals. An orebody thus becomes oxidized and generally leached of many of its valuable materials down to the groundwater table, or to.
