US5223024A  Hydrometallurgical Copper Extraction Process

US5223024A Hydrometallurgical Copper Extraction Process

A process for the extraction of copper from a copper ore or concentrate comprises first subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure in the presence of oxygen and water to obtain a resulting acidic leach liquor which contains dissolved copper. The acidity of the resulting acidic leach liquor is then reduced by affecting percolation leaching of ...

Innovations Introduction To Copper Mining Extraction

Innovations Introduction To Copper Mining Extraction

Copper Applications in Metallurgy of Copper Copper Alloys. Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore.

The copper ore of a copper mine in Zimbabwe is mainly copper-bearing pyrrhotite and high-copper skarn ore. The copper grade of the original ore is 1.25%, and its iron grade is 30.73%. The copper minerals in the ore are mainly chalcopyrite, followed by porphyry, and a small amount of chalcocite, covellite, malachite, etc.

Copper Ore  An Overview Sciencedirect Topics

Copper Ore An Overview Sciencedirect Topics

In most cases, the thin-layer process was used where crushed ores (80% ?0.5 in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 Lhour ?1 m ?2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.

mainly for recovery of gold, copper, and uranium, from low-grade ores, mining and processing waste [2–6,16–19]. The twenty percent of the world’s copper production is accomplished by heap leaching of ores from mines and processing plants as well as waste ores from dumps and further processing by solvent extraction and electrowinning (SX ...

What Is Copper Smelting With Pictures

What Is Copper Smelting With Pictures

Kirsten C. Tynan Copper wire. Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.
