In situ leaching of copper: Challenges and future

2015-10-1  Some intact copper ISL projects have attempted to use column leaching of fragmented ore (Brewer, 1998, Huss et al., 2014, Isaacson et al., 1990, Schmidt and Earley, 1997), but this approach has limited ability to emulate leaching of an intact formation for several reasons. Crushing exposes fresh mineral surfaces to the lixiviant, whereas the

Management of Copper Heap Leach Projects: A Geologist’s

Copper production by heap leaching, coupled with solvent extraction and electrowinning (SX-EW), is a well-established technology, with an annual output of about 3.7 million tonnes (Mt) of copper metal. Ores presently amenable to copper heap leaching include copper oxides and secondary copper sulfides.

Copper Leaching Practices

2021-2-5  Copper minerals leachable by inplace leaching are the same as those leachable by dump leaching, again since the leaching cycle is measured in years. Vat leaching principally employs the dissolution of copper oxide minerals by sulfuric acid from crushed, nonporous ore material that has been placed in confined tanks.

Bioleaching of Copper SpringerLink

Abstract. Natural bioleaching has been taking place for almost as long as the history of the world, but it is only in the last few decades that we have realized that bioleaching is responsible for acid production in some mining wastes, and that this bacterial activity can be used to liberate some metals. The application of the bioleaching

In-situ leaching recovery of copper: what’s next

In situ leaching (ISL) involves the application of a specific lixiviant to dissolve en masse minerals within the confines of a deposit or in very close proximity to its original geologic setting. Currently there is considerable interest in applying ISL technology to recover copper.
