Abstract

Language:

Heap leaching is an attractive process for low-grade deposits where the metal content of ore does not justify the high cost of milling and agitated leaching. The objective of this study is to investigate improvements in gold recovery rates in heap leaching operations. Methodologically, the paper discusses the parameters affecting recovery rates, including ore characteristics such as mineralogy and particle size, and operational conditions like segregation of ore and leach cycle time. The findings indicate that significant recovery improvements could be achieved, potentially converting more lower-grade deposits into minable reserves and allowing for the processing of primary sulfide ores. It is highlighted that a large portion of gold operations' tailings could also serve as a valuable low-grade material source for heap leaching. The paper emphasizes the design considerations for heap leach operations and explores innovative processes such as fine crushing and bioleaching. Overall, this research contributes insights into enhancing gold heap leach recoveries, thus expanding the technology's applicability in the mining industry.
