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.

Genesis Of Lateritic Iron Ore From Banded Iron

Lateritic weathering of metamorphosed Proterozoic banded iron formation (BIF), locally named itabirite in Brazil, produced large deposits of iron ore. At the Capanema iron ore mine in the Quadrilatero Ferrifero in Minas Gerais state (southeast Brazil), the BIF is a bedded metasedimentary rock composed essentially of layers of hematite kenomagnetite alternating with layers of quartz.
