Sulfuric acid solution containing ferric iron is the extractant for industrial heap bioleaching of copper sulfides. To start a heap bioleaching plant, sulfuric acid is usually added to the irrigation solution to maintain adequate acidity (pH 1.0–2.0) for copper dissolution. An industrial practice of heap bioleaching of secondary copper sulfide ore …

for copper sulphides. Three copper sulphide leaching and refining processes are discussed: total pressure oxidation, ferric sulphate leaching and copper chloride leaching. Ferric sulphate leaching and copper chloride leaching are carried out at atmospheric pressure while total pressure oxidation takes place at elevated pressures.

Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves. The amount of copper …

The most common types of copper ore are copper oxide and copper sulfide. Copper oxides are more abundant near the surface, but are considered low-grade ore. Copper sulfide ore, which accounts for 80% of the copper resource, is the major source of metallic copper. Copper processing is a complicated process that begins with the mining of the …

All copper sulfides require the presence of Fe 3+ and O 2 as oxidizing agents for leaching to occur. The copper sulfide is oxidized by Fe 3+.The resulting Fe 2+ is reoxidized to Fe 3+ by O 2.The Fe(II)/Fe(III) redox couple acts in a catalytic manner in these reactions (shown for elevated-temperature reaction conditions where the sulfur-containing product is …

Processing plants for porphyry copper ores are generally very large, processing up to 200,000 tpd of ore (JX Nippon, 2018)), and emphasis is put on throughput. Ores with low pyrite content (<2%) are generally considered easier to process (and the reagents scheme only includes copper collectors, pH regulator, and frother).
