Title
Hardpan Formation in Mine Tailings: Effect of Climate, Mineralogy and Mineral Processing on its Formation,Used
Delivery time: 8-12 business days (International)
In this study, mine tailings located in different climatic regions were studied for their mineralogical, geochemical, physical properties and the tailings discharge techniques used to understand the process affecting hardpan formation. This was combined with column experiments for monitoring the transport/precipitation processes. Thickened tailings discharge in Egypt did not allow grainsize/mineral segregation and therefore the critical amount of reactive mineral phases cannot be achieved. This, with high carbonate contents and hightemperature/lowwater availability did not allow significant oxidation of sulfides and decrease hardpans possibility. Spigot tailings disposal in Germany with enrichment of reactive phases in certain lamina, combined with periods of raining and drying events enhances the process of hardpan formation. Hardpan development is highly enhanced in areas with high temperature, water content, high reactive minerals, repetition of drying/wetting cycles and long reaction time. This work shed some lights on the process of hardpan formation to minimize the environmental problems developed in inactive mine sites, especially those with high sulfide contents.
By changing our most important processes and
