Hardpan Formation in Mine Tailings: Effect of Climate, Mineralogy and Mineral Processing on its Formation

Hardpan Formation in Mine Tailings: Effect of Climate, Mineralogy and Mineral Processing on its Formation
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 grain-size/mineral segregation and therefore the critical amount of reactive mineral ... إقراء المزيد

Reactive transport modelling of weathering processes in intensely stratified mine tailings

Reactive transport modelling of weathering processes in intensely stratified mine tailings
Reactive transport simulations have been applied to investigate possible effects of stratification on the potential of sulfide-bearing mine tailings to form protective cemented layers and to retain toxic elements. Our research is based on a German tailings site, where material is intensely stratified on a mm-cm scale. The computational domain was defined as an one dimensional column the size of ... إقراء المزيد

Understanding micro-environment development in mine tailings using MLA and image analysis

Understanding micro-environment development in mine tailings using MLA and image analysis
In the course of ore mineral treatment large amounts of mineral residues will be deposited in tailings dams. The spilled material might contain some amount of valuable as well as hazardous material. The spilling process generates vertical and lateral mineral and grain size fractionation. Mine tailings therefore show distinct chemical and mineralogical pattern along the spilling path and across the ... إقراء المزيد

Application of Mineral Liberation Analysis in studying micro-sedimentological structures within sulfide mine tailings and their effect on hardpan formation

Application of Mineral Liberation Analysis in studying micro-sedimentological structures within sulfide mine tailings and their effect on hardpan formation
In this paper, mineral liberation analysis (MLA) was applied as a new approach to elucidate and quantify textural, mineralogical, and chemical variations on a μm/mm scale to understand the alteration processes relevant for hardpan formation at the Davidschacht mine tailings in Freiberg, Germany. Additionally, the bulk mineralogical, geochemical, and physical properties were investigated in detail. Within the upper 1.5m of ... إقراء المزيد
