In arid and semiarid regions, plant establishment on mine tailings is further impeded by a number of physicochemical factors including extreme temperatures especially at the tailings surface, low precipitation, and high winds.
INTERACTIVE EFFECTS BETWEEN LIME, ORGANIC MATTER, ... LEYMUS CINEREUS IN MINE TAILINGS by ... microbial community is likely to play a crucial role in the establishment of plants in toxic mine soils. These microbial communities can change redox conditions in the soil, influence plant growth, increase or decrease metal toxicity, and influence ...
Abandoned mine tailings from a wide variety of industries are found around the world. The chemical composition of tailings depends on the minerals mined and the extraction technique. For example, cyanide compounds have been used in some gold (Au) operations.
Tailings reclamation by plants was studied at presence of pig slurry and marble waste. • After five years, A. halimus was the most dominant species growing on the tailing. A. halimus accumulated metals in leaf higher than in stem and root.. The treatments decreased bioaccumulation index of Zn and Cd but increased that of Pb.
The influence of organic matter for plant establishment on tailings Plant growth and survival in sulphide mine tailings are restricted due to several factors. High levels of sulphide minerals such as pyrite may, when exposed to oxidation, decrease pH in the tailings and release toxic levels of metals (Ferguson & .
Algom Ltd.) research has focused on marsh and floating plants, while on nickel tailings (Falconbridge Ltd.) submerged plants were studied. In addition, factors affecting the growth of one species of submerged plant at the two sites were compared in a reciprocal transplant experiment. QUIRKE MINE WASTE MANAGEMENT

Keywords: efflorescence salts, dust ... all principal factors extracted from the variables were ...
2.5.5 Host Plant 2.5.6 Plant Cover and Time ... A literature review was carried out on the factors affecting the establishment ... Mine sites create considerable disturbance to ecosystems during the construction of pits, overburden dumps and tailings. Without active restoration
Seedling establishment on iron mine tailings in New York State's Adirondack Park was studied to determine if cover by the bryophyte Polytrichum piliferum Hedw. facilitated or inhibited seed germination and seedling survival, relative to other substrates present on the site. The occurrence of vascular vegetation on the four most commonly occurring substrates (bare tailings, cryptogamic crust ...
The aim was to examine the effects of plant establishment on water-covered mine tailings by answering following questions: A) Is plant establishment on water-covered mine tailings ... 3.2.1 Factors affecting the metal and As plant uptake.....22 3.2.2 Translocation properties.....25 3.2.3 Comparing metal and As concentrations in plant shoots ...

Beneficiation routes for upgrading iron ore tailings with a teetered . Sep 14, 2016 Although iron ore tailings are sometimes admitted as secondary resources for . only with coal, but with regard to iron ore processing, chromite, beach sands, metal from tail of the dry low intensity magnetic separator in an iron ore beneficiation plant. ..
FACTORS AFFECTING VEGETATION ESTABLISHMENT The principal factors affecting seedling establishment and plant growth in mine waste rock and tailings materials are spoil stability, moisture retention, drainage, fertility, soil temperature, surface crust formation, heavy metal toxicity, pan formation in materials, salinity and acidity.
May 27, 2018· The resulting post-mining sand tailings lacked requisite soil nutrients and structure to support ... The edaphic factors affecting tree growth on the rehabilitation sites were analyzed; based on assessment ... Jones, 2001), Guide to Laboratory establishment for plant nutrient analysis (Motsara and Roy, 2008) and the FAO (ISRIC/FAO, 2002). Data ...
The productivity of plants depends largely on climate and the fertility of the growing medium. Tailings fertility is related to: The physical properties of the tailings which influence the amount of water that can be held in the profile and the ease with which roots can penetrate, and; The tailings .
Previous work on the project determined the conditions required to grow metal- and drought-tolerant plant species in mine tailings dirt under greenhouse conditions. The current projects seeks to translate the findings into the field, by establishing a plant cover in a pilot plot on the Iron King mine tailings Superfund site in Dewey-Humboldt, AZ.
Introduction. Waste tailings dumps from either inactive or abandoned mine sites are prevalent in various parts of the world. The global impact of such tailings dumps is enormous, as unreclaimed mining sites generally remain unvegetated for tens to hundreds of years (Mendez & Maier,).Natural recolonization of plants on mine tailings is difficult, as these degraded materials typically have no ...
The long-term goal of this study is to define limiting factors for phytoremediation of mine tailings and other sites contaminated with heavy metals. This study will establish the scientific basis for the remediation of mine tailings and extrac-tion of heavy metals by phytomining techniques.
tailings dams have been largely subjective and based on visual inspection (Randall, 2004). Rehabilitation progress has been judged mostly on the successful establishment of vegetation on tailings dams. Hence, much of the research so far carried out has focused on species trials and optimum conditions for plant growth on tailings (Hill, 1977 ...
Aug 13, 2015· Although abiotic factors pose significant constraints for plant establishment in mine tailings 50, the development of microbial diversity is also crucial to facilitate and sustain plant .
Factors Affecting Decomposition Properties of Paper Mill Sludge Spread on Mine Tailings Jennifer Braun and Peter Beckett Department of Biology, Laurentian University, Sudbury, Ontario, P3E 2C6 Canada [email protected] Abstract Paper mill sludge is being used increasingly as means of remediating mine-contaminated soils but in order to ensure the refinement and success of these ...
Dec 17, 2007· In arid and semiarid regions, plant establishment on mine tailings is further impeded by a number of physicochemical factors including extreme temperatures especially at the tailings surface, low precipitation, and high winds.
