Heap leaching

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and reseparate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...

Heap Leaching

Heap leaching is a widely used extraction method for lowgrade minerals, including copper, gold, silver, and uranium. This method has new appliions in nonmetallic minerals such as saltpeter and soil remediation. Although a number of experimental studies have been carried out as well as modeling, which allows better understanding of the ...

Heap Leaching: Modelling and Forecasting Using CFD Technology

Heap leach operations typically employ some form of modelling and forecasting tools to predict cash flow margins and project viability. However, these vary from simple spreadsheets to phenomenological models, with more complex models not commonly employed as they require the greatest amount of time and effort. Yet, accurate production modelling and forecasting are essential for managing ...

Copper Heap Leaching SXEW Slideshow

Heap leaching SXEW is a method of extracting pure copper from oxide ore by placing the crushed ore on a pad in a heap and spraying the leaching solution, sulphuric acid, over the heap. The acid trickles through the heap and dissolves the copper mineral into solution. The leach solution collects at the bottom of the pad in a collection pond.

However, heap hydrology is prone to nonuniform behaviour due to the inhomogeneity of the ore particles and the heap structure. The primary aim of this thesis was therefore to develop a magnetic resonance imaging (MRI) technique which would allow for the novel noninvasive imaging of the liquid holdup in representative laboratoryscale heap leaching systems.
