2014-10-1 promote the application of HPGR prepared Heap Leach processing for large tonnage projects are presented in the paper. Of note is the potential dual use of the crushing circuit for both the main CIL/P plant and the heap leach. HPGR has been shown to influence the extraction and kinetics of leaching low grade gold ores.

2016-12-27 Fig. 3. Heap leach recovery vs. crush size At the end of the simulations, 80% of -4.65 mm crushing product target with 55.4% -3.35 mm was achieved with the capacity around 200 (±10%) Mg/h. Particles having 3.35 mm was the leach size for the best recovery. Figure 3 shows the heap leach recovery versus crush size for the process.

2017-11-2 optimal HPGR operation, agglomeration, heap construction, leach practices and avoidance of heap compaction. Although HPGR’s major benefit to hydrometallurgy is its micro-fracturing of the rock matrix, it does generate some finer product sizes which are inherently beneficial for gold heap leaching. Extensive testing between 1996 and

2013-2-1 Whereas in actual heap, as discussed in next section, the coarse rock size distribution contributes significantly to slow leach kinetics (Hernandez et al., 2003). Also, in similar agglomeration conditions, the heap leach results were different from the column tests due to more compactness of heap and also the absence of structural support ...

This paper discusses the concept of applying HPGR technology to the preparation of low grade gold ores for heap leaching. Examples of recent testwork results from four Western Australian projects are discussed with key issues for the flowsheet development team identified. Understanding the leach extraction and therefore the lowest cut-off grade that can be fed to a HPGR heap leach circuit is ...
