In this paper, the Guangxi’s red mud disposal field is taken as the study area. Appropriate calculating parameters and boundary conditions were selected based on the survey data to build a Mohr-Coul0mb and fluid model under the plane-strain condition. FLAC software was adopted to simulate the distribution of pore water pressure, filtrate seepage paths, and leakage of the dam body under conditio...

Jarosite waste, originating from zinc extraction industry, is considered hazardous due to the presence and the mobility of toxic metals that it contains. Its worldwide disposal in many tailing damps has become a major ecological concern. Three different methods, namely modified Synthetic Precipitation Leaching Procedure (SPLP), three-stage BCR sequential extraction procedure and Potential Ecolo...

The study of Technosols development, spatial distribution and physicochemical characteristics is becoming more important in the Anthropocene Era. aim present was to assess soil features potential heavy metal release risk soils developed on different mine tailing types after waste disposal derived from mining activity Central Italy. Soils were analyzed for their morphological, physical chemical ...

A sample from the small-sized tailing pile of an Iranian mica processing plant was subjected to a series of mica recovery experiments. Mineralogical and microscopic investigations indicated that the dominant mica mineral was phlogopite which was accompanied by plagioclase feldspars. Before beneficiation studies, the particle size distribution of the representative sample was obtained, and the s...

There are numerous examples of past and present mine disposal into freshwater and marine coastal bays and riverine environments. Due to its high spatial resolution and extended water penetration, coastal light detection and ranging (LiDAR), coupled with multispectral scanning (MSS), has great promise for resolving disturbed shoreline features in low turbidity environments. Migrating mine tailin...

Mining and processing of minerals produce large quantities tailings as waste. Some countries, including Norway, allow disposal mine in the sea. In this study we investigated impacts from a calcium carbonate (CaCO3) plant on early live stages haddock (Melanogrammus aeglefinus) Atlantic cod (Gadus morhua). Fish eggs (3 days post fertilisation; dpf) were exposed for 48 h to three concentrations ta...

The disposal of industrial and mineral processing residues represents a major concern for human health the environment as whole. In order to reduce impact on soil groundwater due waste leachability, implementation environmental regulations worldwide has favored conversion techniques from wet dry (i.e., stacking or disposal). Such change in storage practice may cause increase particulate matter ...

This paper focusses on the description of reliable, safe and economical treatment of mine water from different types of mines and applications by advanced membrane systems. The applications include mine drainage water from underground mines, intrusion water in open pit mines and excess water from tailing storage facilities. The illustrated references confirm the existence of robust, reliable, a...
