The method employed comprised open-air water leaching of weathered piles of copper-bearing ore followed by precipitation of the copper by iron. A description of leaching and precipitation of copper at Rio Tinto in the 20th century is given by Taylor and Whelan. This method is essentially the same as that practiced at present by most of the ...

Copper is soft but tough. It is easily mixed with other metals to form alloys such as bronze and brass. Bronze is an alloy of tin and copper and brass is an alloy of zinc and copper. Copper and brass are easily recycled¿perhaps 70% of the copper now in use has been recycled at least once. The Properties of Copper.

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. Underground mining is, however, relatively expensive and is ...

If copper tailing is constant, and it very nearly is for a strictly sulfide copper ore, percent recovery must fluctuate almost directly to the feed assay. The accuracy of a recovery figure is first of all dependent on the accuracy of sampling and assaying. Sampling and assaying errors can become quite significant in the case of low grade ores.
