The heap leaching of copper ores is an example of such a trend, where heap leaching was initially applied only to the acid leaching of oxide ores. The most important factors to be considered in oxide heap leaching are the copper dissolution, acid consumption, and gangue chemistry.

Agglomeration of finesized copper ore in heap

2020121Before leaching, lowgrade copper ores are typically crushed using highpressure grinding rolls to induce the formation of numerous microcracks and fine mineral particles Yin et al., 2017 this step can accelerate the leaching process and increase the leaching recovery, but it reduces the penetration of the leachate into the ore. The objective of the present study was to examine the

Application of SART to Heap Leaching of GoldCopper

Kinross Gold Corporations Maricunga mine in Chile presents an ideal opportunity to apply the SART process to a heap leach operation. Given increasing levels of cyanide complexed copper in current pregnant solutions from Maricunga heaps over 300 ppm Cu, there is a need to reduce these levels and decrease cyanide consumption and cost. Additionally, a means of disposing of this copper is required, preferably as a saleable product. The well published SART process applied to goldcopper cyanide solutions was selected as it allows rapid precipitation of cyanide soluble copper as a relatively pure copper sulphide. The process also allows effective recoveryand recycle of cyanide back to the heap

2.1 Leaching. Most copper leaching is done by piling broken ore 0.5 Cu into flatsurface, 310m high, 10 4 10 5 m 2 heaps of ore and then sprinkling dilute sulfuric acid lixiviant on to the heap surface. The lixiviant trickles down through the heap and leaches copper from its minerals to produce a pregnant leach solution containing 15kg Cum 3.

201668Copper ore bodies are typically composed of three distinct zones Figure 1. Weathering and oxidation convert the copper in the top layers of the orebody to copper oxide minerals, and this represents approximately 10 of the total copper. A transition from the

Gold Extraction Recovery Processes 911 Metallurgist

2 Heap leaching can be considered as a percolation process on ore piles. The process is characterized for its economic cost against the agitated leaching process when the ore deposit has a low gold content. Typically the process can process ores whose gold content is 0.81.1 g/t.

In some instances the ore can be mined and directly leached without any further processing, this is called runofmine ore. In many instances, the ore requires crushing and/or grinding to expose more surface area prior to leaching.
