Nov 01, 2020· Under the neutral pH of the mine tailings substrate of our samples, due to the absence of sulphide reactive minerals (Conesa et al., 2008), other parameters such as electrical conductivity (including water extractable chloride and sulphate) or texture (particle size distribution) seemed to play an important role in plant species establishment.

Phytostabilization ofmine tailingsis a promising remedial technology but requires further research to identifyfactors affectingits long-term success by expanding knowledge of suitableplantspecies andmine tailingschemistry in ongoing field trials.

Phytomanagement has been considered a feasible technique to decrease the environmental risks associated to mine tailings and its implementation relies on a suitable plant species selection. The goal of this study was to identify the edaphic factors, including microbiology, affecting the establishment of plant species with contrasting growth patterns during the phytomanagement of mine tailings.

In addition, there are otherfactors affectinggold ore leaching, such as associated impurities in ore, amount of leaching aid, etc., which are various due to the ore differences, so they are not discussed here. Then, we will explore the impact of the abovefactorson gold leaching. 1. Grinding fineness

Jul 19, 2019·Mininginvolves the processing of mined ore to separate valuable minerals, leaving behind huge volumes of wastetailings. Driven byminingvolumes, globally generatedtailingsare estimated to ...

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.

Physical and chemical factors affecting successful vegetation establishment are controlled by the maintenance of a saturated substrate which prevents pyrite oxidation and acid production. The moist soil zones provided by the saturated slurry substrate represent a favorable root growth medium similar to natural wetlands.

Generally, the gold beneficiationplantwill reasonably research and apply the separation of coarse and fine particles of thetailingsclassification based on the loss of thetailingsparticle size metal amount withoutaffectingthe original production, so as to further recover the gold in thetailingsand improve the concentration recovery ...

To help determine the design requirements of a tailings storage facility, the following characteristics of the tailings will need to be established (based on EC 2004): Chemical composition (including changes to chemistry through mineral processing) and its ability to oxidise and mobilise metals.

Similar to other mineral processing solutions, there are manyfactorsthataffectthe copperminingprocessing. Only recognizing thesefactorsin copperminingprocessing designing can we improve the economic benefits of the coppermining plant. Particle size is an important parameter of influencing the result of copperminingprocessing.

Mar 14, 2019· Plant growth on tailings was limited by a lack of available nitrogen (N) and high alkalinity (pH >9), and seedling growth and development was positively associated with seed N concentration.

The main obstacle to phytostabilization success is that most tailings are a poor substrate for plant growth due to both the abiotic stress posed by some combination of metal toxicity, low pH, high salinity, lack of essential minerals and nutrients, poor soil structure and water retention, and the absence of a suitable microbial community to sustain plant growth.

On a global scale, the demand for mineral products has increased substantially with economic development. Consequently, theminingof mineral resources results in the production and accumulation of a large number oftailings, causing many problems with respect tomining, the environment, and the economy. In theminingprocess,tailingsmust be reasonably treated to prevent them from entering ...

Abstract:Tailingsrehabilitation, using soil-like properties with chemical and physicalstability, can be influenced by surface forces on a particle scale and microstructure. Non-homogeneous structures, manifesting as particle aggregation, alter the permeability/porosity and improve the balance of aerated and water-filled pores that then favoursplantgrowth.

It is possible to find a wide variety of plant species that can colonize areas highly polluted with heavy metals and metalloids, such as mine tailings or soils degraded and contaminated by mining/industrial activities. These are referred to as metallophyte and pseudometallophyte species.

For this type of disposal it is therefore more efficient to dewater thetailingsat theplant(Davies and Rice 2001).
