Metals such as gold, copper and lead can be found in soil at high concentration at many desert locations. However, adverse weather conditions, specifically a lack of moisture, limit the range of applicable technologies to recover these metals. A number of plant species have been tested under both laboratory and field conditions to determine their potential for use in the phytoextraction of

2021-1-1 The arid and semiarid regions are present in quite vast areas of the world; this is about a third to a quarter of the total landmass . Soils are often saline since evaporation rates are higher than rain and the presence of natural salts derived from saline rain, nondegraded minerals, and fossil salts ( Mendez and Maier, 2008 ).
In arid and semiarid regions, dry-stacking facilities are most common wherein tailings are dried, spread out, and compacted. However, they remain unstable and subject to eolian dispersion and water erosion with the potential to contaminate nearby communities and environmentally sensitive areas ( Gonzalez and Gonzalez-Chavez 2006 ; Schwegler 2006 ).

2013-5-1 Highlights Gold phytomining is potential route for economic exploitation of precious metal. Metal extraction is by hyperaccumulating plant species from low grade ore bodies. Phytomining has potential to meet the increasing demand of gold in metal market. Economy depends on soil metal content, metal uptake, plant biomass, metal price. Technology is environment friendly, aesthetically pleasing

The mobility and microbially mediated solubilization of Au and As in regolith materials from two Au mines in Australia, i.e., the Peak Hill Gold Mine in semi-arid New South Wales and the Hit or Miss Gold Mine in tropical northern Queensland, was studied using a combination of geochemical and microbiological techniques. Gold is highly mobile in both environments, the mobility of Au increases
2010-8-9 The paper outlines the setting, mining, milling and waste disposal at Kidston Gold Mine's open pit operations in the semi-arid climate of North Queensland, Australia, before focusing on the engineering aspects of the rehabilitation of Kidston. The mine took a holistic and proactive approach to rehabilitation, and was prepared to demonstrate a
2021-2-9 Three arid zones can be delineated by this index: namely, hyper-arid, arid and semi-arid. Of the total land area of the world, the hyper-arid zone covers 4.2 percent, the arid zone 14.6 percent, and the semiarid zone 12.2 percent. Therefore, almost one-third of the total area of the world is arid land.

2006-6-16 However, water availability is doubtless the limiting factor for tree growth in semiarid and arid areas (Zahner, 1968). In the present study, moisture availability during the growing season, cumulatively aggravated by water deficits in preceding years, is the dominant factor controlling the formation of narrow tree rings and narrow latewood bands.
2018-8-10 In arid and semiarid regions, on the other hand, the small number of lakes and the great distances between them reduce the possibilities for correlation. Moreover, since lake levels are controlled by rates of evaporation as well as by precipitation, the interpretation of such levels is ambiguous.

2021-6-3 Along with the accelerated shift of coal mining to the ecologically fragile west, the contradiction between coal resource development and ecological protection in the western arid and semiarid coal mining areas is rapidly intensifying. Based on the above background, this thesis takes the coal mining area in the arid and semiarid regions as an example; applies the theories of ecology, coal
2020-12-4 Many industrial raw materials can be supplied by renewable, domestically grown, agricultural crops. However, very little is known about how to grow and process most of these underutilized, sometimes undomesticated, plant species. This project examines the agronomic requirements of these promising, but poorly understood, alternative crops that may be suitable for semi-arid climates.

Some endemic shrubs in arid and semiarid ecosystems are in danger of extinction, and yet they can play useful roles in maintaining or restoring these ecosystems, thus practical efforts are needed
2021-8-4 In humid regions SOC is higher than SIC, while in arid regions SIC is higher. Arid regions contain roughly 78% of the global SIC, semiarid 14% and humid regions less than 1% . The amount of SIC within arid regions is notably affected by three factors: extreme aridity, parent material and soil age .
