Investigation into the semi-dynamic leaching ...

The leaching characteristics of metallurgical slag-based binders (MSB) solidified/stabilized tailings containing arsenic (As) and antimony (Sb), were investigated via a series of semi-dynamic leaching tests using three kinds of leachant, for the simulation of actual leaching conditions.

How to Determine Dynamic Permeability of In-Situ Leaching

The process of in situ leach mining involves geologic, geochemical, hydrologic, geomechanical factors which need to be investigated in designing leaching operations. The permeability of the orebody to be leached is particularly important. The objective of this study is to investigate permeability conditions of the Cyprus Casa Grande mine in order to better understand the hydrologic behavior of ...

The 7.2 cm event on May 8 was the preplant irrigation. The leaching pattern for both cases is chronologically consistent with the N concentrations and water fluxes shown in figure 7. The rate of N leaching was relatively low for AW/PET = 1.42 until the end of July, after which point the rate increased.

Heap Leaching - Hatch

At the same time, they're constantly on the lookout for suitable and cost-effective equipment and systems for every heap-leaching project. Understanding the time-rate-of-recovery dynamics in heap-leach operations is mandatory for analyzing the financial performance of any mining operation. It's also a must for the successful execution of a project.
