Copper Price

Copper prices. Historically unstable, the market price of copper frequently fluctuates. Hitting a 60-year low of $0.60 US per pound in 1999, the copper price climbed throughout the 2000s, soaring to $3.75/lb in 2006. Prices experienced a pullback to a low of $1.26/lb in 2008, persisting into 2009 with an average closing copper price of $2.37.

Improvements in Copper heap leaching by use of

2013-10-14 leaching conditions must aim on shorter leaching times as well as on a higher copper extraction rate, thus to an increase in copper productivity and lower costs per ton of copper. Because leaching processes include interactions between solid (ore) and liquid (sulfuric acid) phases such improvements may be achieved by the use of wetting agents.

Copper Leaching at Gunpowder AusIMM

Copper has been mined intermittently at Gunpowder, north of Mount Isa, since 1927. Most ventures have had some initial success but fluctuating copper prices, the small-scale of the operations and the remoteness of the site led to closures or sale. Processing routes have included direct sale of high grade ore, flotation of oxide and sulphide concentrate, and copper cement
