Mine Tailings an overview ScienceDirect Topics
Neverthless, transgenic plants would provide more suitable plants for increased secretion around roots to aid radionuclide uptake and binding, and better overall growth and biomass to absorb and remediate radioactive sites. The use of trees and forests leads to considerable savings in remediation of radioactive sites, as clearly demonstrated by removal of tritium in wastewater. The likelihood
plants growing at the tailings of mining sites
plants growing at the tailings of mining sites. Tailings management is a mineral processing waste management issue. Tailings may be stored in a variety of ways, depending on their physical and stone nature, the site topography, climatic conditions, and the socio-economic context in which the mine operations and processing plant are located.

Effect of Mine Tailings on the Growth of Ornamental Plants
Index Terms- Mine tailings, ornamental plant growth, soil alternative I. INTRODUCTION ine tailings (also called “slimes”) are sand-like waste products of the mining process. In the early mining days, tailings were discarded in low-lying areas or lakes and streams near the mines. Over time, these tailings can move through the environment and may be redistributed over larger areas of land
Plants from the abandoned Nacozari mine tailings

as mine tailings. Mining sites all over the western United States and Mexico have tailings piles, some of which stretch for acres and acres and have been almost devoid of plants for more than 100 years. “Some piles are so toxic and the material is so unlike soil that nothing grows there,” says Raina M.

Pers. (rehabilitation site). The results indicated that 18 herb species were taken from 8 families and 4 woody plants in three sites after 1 year. After 3 years, 29 species from 14 families were observed in 3 sites. Meanwhile, compared with tailing site, the plant species of rehabilitation site was more than tailing site, and the plant
Environmental Risks From Mine Tailings
10.08.2018· Tailing Ponds . Some mining wastes become very fine after they have been ground up during processing. The fine particles are then generally mixed with water and piped into impoundments as a slurry or sludge. This method cuts down on dust problems, and at least in theory, the impoundments are engineered to let excess water flow out without leaking tailings. Coal ash, while not a type of tailing

Mining companies are making significant investments in studying ways to improve the security and safety of tailings depositions. Several sites have started separating acid-generating material from the bulk of their tailings in order to significantly reduce the volume of tailings that require ongoing management and to create a more environmentally sustainable tailings storage facility (TSF). In
Tailings.info What Are Tailings? Their nature and
Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and stone processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings. This process of product extraction is never 100% efficient, nor is it possible to reclaim all reusable and expended processing reagents and

The dominant plants growing on mine tailings belonged to the families Gramineae and Compositae, and the most widely distributed plant species were Imperata cylindrica, Cynodon dactylon and Paspalum distichum. Coreopsis drummondii also grew well on the arid sites but not on wet sites. Very low or zero arbuscular mycorrhizal (AM) fungal colonization was observed in most of the plants, but

Soil contamination with trace elements in the vicinity of mining sites and smelters poses a serious threat to humans and the environment around the globe. Revegetation of mine tailings to minimize the dispersal of pollutants via wind or groundwater (i.e., phytoremediation) is a promising "green" and low-cost intervention to toxic exposures. Unfortunately, plant growth is inhibited on most

Safety First The Peoples’ Tailings Standard To End Mine
Tailings facilities, which contain the processed waste materials generated from mining metals and minerals, are failing with increasing frequency and severity. The safest tailings facility is the one that is not built. To avoid the long-term liability of mine waste sites and their social and environmental impacts, we must reduce the volume of tailings produced, as well as the overall demand
Disposal Methods on Solid Wastes from Mines in Transition
01.01.2012· Because of the diversity of stone fineness in different mineral processing plants, tailings can be classified to coarser size and the fine size. For most mines, the coarser tailings could be used as fine aggregate of concrete and the fine size tailings are good materials for making bricks. Using iron tailings, Das et al [10] succeeded in making floor tile and wall stone for construction. These
