LEACHING OF LOW-GRADE COPPER ORES: A CASE STUDY FOR
This paper deals with the investigation of column leaching of low-grade ores from the copper mine Cerovo, Serbia (the approximate Cu content in the ore ranges from 0.2 0.3 % with >10 % copper in the form of oxide minerals). The leaching experiments were performed using sulphuric acid solutions, whereby the kinetics of copper leaching was investigated with respect to acid
How to Improve the Effect of Gold Cyanide Leaching? Xinhai
29/09/2019 When the content of soluble copper and zinc in a gold mine is relatively low, increasing the oxide can improve the rate of gold cyanide leaching if the increase of cyanide does not cause economic loss. However, it should be noted that this method must be conducted at a lower temperature and cyanide concentration, because the dissolution rate of the same
Copper Mining and Extraction: Oxide Ores
Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.

Whim Creek Project ANAX Metals Limited
The discovery of gold and copper in the Whim Creek area in the early 1880s led to a period of underground, artisanal mining until 1912, during which high grade copper-gold ore shoots were targeted. Systematic exploration by various companies in the 1960s, including Texasgulf, defined the known VHMS deposits of the Whim Creek Greenstone Belt, namely Whim Creek, Mons
In situ recovery, an alternative to conventional methods
Copper is the most popular commodity (after uranium) that is mined by ISR (Table 1). There are references to primitive forms of in situ leaching of copper in Roman times, and maybe even long before that in China (O'Gorman et al., 2004). The San Manuel copper mine in Arizona is the best known copper mine exploited by ISR (O'Gorman et al., 2004

Gold and Silver Leaching Practices in the United States
eta1 values are recovered from cyanide leach solutions using either zinc precipitation or charcoal adsorption. Potential problems that may hamper on block development of a leaching operation are poor percolation characteristics of the ore, calcium salt buildup, low tem- peratures, and solution losses. An extensive bibliography on gold and silver leaching is appended.
