Apr 25, 2017Copper is a naturally occurring metal that gives off a stunning reddish-orange metallic color when polished. Its chemical symbol is Cu, and atomic number is 29. Mining operations extract copper from the ground via open pit mines. Once the copper-containing earth is extracted, the extract is ground to fine ore and put through a froth flotation process.

Davis et al. (1998) proposed a similar SX route but with cyanide recovery based on LIX 7820 to concentrate the copper to 3040 g/L (in 50 g/L total cyanide, 10 g/L NaOH) from dilute liquors containing 1 g/L of copper and 1.7 g/L total cyanide.

The cyanide acts by reacting with copper in solution, first reducing Cu 2 to Cu then forming soluble cupro-cyanide complexes, Cu(CN) x 1−x (e.g., Cu(CN) 2 −), which are stable and prevent the uptake of copper by Eq. (12.9). The form of the complex depends on

This study was undertaken to develop a cost-effective method of copper leaching in sulfide concentrate involving minerals as chalcopyrite and pyrite. The combined methods involving low temperature roasting of sulfide copper minerals with potassium chlorides without the formation of sulfurous gases and their evolution into the atmosphere is suggested.

In this experiment an insoluble metal oxide is reacted with a dilute acid to form a soluble salt. Copper(II) oxide, a black solid, and colourless dilute sulfuric acid react to produce copper(II) sulfate, giving a characteristic blue colour to the solution. From this solution, blue copper(II) sulfate pentahydrate crystals can be obtained.
