Sulfide Ore an overview ScienceDirect Topics

Sulfide Ore. Sulfide ores, which are generally mined from underground and often found in conjunction with copper-bearing ores, contain copper–iron sulfides in association with nickel–iron sulfides. oxygen-enriched air (30–40% oxygen), or pure oxygen.

supergene sulfide enrichment geology Britannica

supergene sulfide enrichment, also called Secondary Enrichment, in geology, natural upgrading of buried sulfide deposits by the secondary or subsequent deposition of metals that are dissolved as sulfates in waters percolating through the oxidized mineral zone near the surface. The ore thus enriched forms the secondary, or supergene sulfide, zone and overlies the primary, or get price
