Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
This report presents a comprehensive overview of the Mongolian gypsum market the effect of recent high impact world events on it and a forecast for the market development in the medium term and environment in order to understand competitive threats; Assess growth potential opportunities demand drivers and challenges on the market
·Based on data from the industrial processing of end of life gypsum plasterboards into recycled gypsum various relevant environmental impacts land consumption climate change were calculated and compared with the environmental impacts from the mining of natural gypsum and the provision of FGD gypsum from coal fired power plants
·As Mongolia is considered one of the most resource extraction dependent countries globally significant mining related environmental and human health risks are expected
·Salinity impedes soil and crop productivity in over 900 million ha of arable lands worldwide due to the excessive accumulation of salt NaCl To utilize saline soils in agriculture halophytes salt tolerant plants are commonly cultivated However most food crops are glycophytes salt sensitive Thus to enhance the productivity of saline soils gypsum
·The results indicated that the effect of FGD gypsum is greatest in the 0 10 cm mixing soil layer and 60 Mg/ha was the optimal rate that can reduce the ESP to below 6% and decrease soil pH to
·The impacts of quarrying of the gypsum deposits on the environment at Maqna Tabuk were evaluated by intensive field studies including in situ testing mapping and sampling of gypsum and well water Field and laboratory tests were made to determine the engineering properties including tensile and compressive strengths unit weight fracture spacing and the
·Forest Management In Mongolia A Review Of Challenges And Lessons Learned With Special Reference To Degradation And Deforestation
Reducing the burden of disease among Mongolian children requires much more focus on preven tion targeting the environmental causes of childhood diseases The aims of this study were to identify and assess the significance of environmental risk fac tors in the Mongolian population assess levels of exposure present the burden of adverse health
·The source and evolution of sulfate SO 4 2 in groundwater from abandoned mines are widely concerned environmental major dissolved ions multi isotopes δ 34 S δ 18 O sulfate δ 2 H and δ 18 O water machine learning Self organizing maps and Bayesian isotope mixing model were used to identify the source and evolution of SO 4 2 in an
·Fertilizers play an essential role in increasing crop yield maintaining soil fertility and provide a steady supply of nutrients for plant requirements The excessive use of conventional fertilizers can cause environmental problems associated with nutrient loss through volatilization in the atmosphere leaching to groundwater surface run off and denitrification
·The global amount of Hg mass accumulated in soils is very large; assumed to be in the range of 250 1000 Gg Obrist et al 2018 Although Hg occurs naturally in soils from geologic sources Obrist et al 2018 or through natural events such as forest fires and volcanic eruptions Ermolin et al 2018 a significant proportion of that Hg is attributed to
·Gypsum salt rock composed mainly of gypsum and anhydrite with small amounts of rock salt salt minerals dolomite and some other constituents is one of the major evaporite rock types Calaforra and Gazquez 2017; Benamara et al 2017; Liu et al 2017 Due to the characteristics of gypsum salt such as solubility variability flowability compactness
·Pu S Zhu Z & Huo W Evaluation of engineering properties and environmental effect of recycled gypsum stabilized soil in geotechnical engineering A comprehensive review
·This study concludes that low electrolyte water had a greater risk of P leaching and associated environmental pollution Leaching of the saline sodic soil amended with gypsum and city waste compost with low SAR saline water can reduce P leaching compared to good quality rainwater The effect of Gypsum amendment on transport of phosphorus
·To explore the possibility of using flue gas desulfurization gypsum FGDG for inhibiting phosphorus P loss due to agricultural runoff a 3 year study was performed in the farmlands of Chongming Dongtan between 2012 and 2015 Five different quantities of FGDG were used to treat the soil and the effects of different treatments on the characteristics of soil
·Polymeric gypsum versus traditional gypsum environmental differences Polymeric gypsum compared to traditional gypsum is distinguished by a number of advantages that make it more environmentally friendly First and foremost modern polymer gypsum formulations often contain plant based or recycled ingredients which significantly reduces the
·Gypsum Products Manufacturing Gypsum is used in the manufacturing of a wide range of products including ceiling tiles decorative panels gypsum blocks and various forms of gypsum based insulation Environmental Remediation Gypsum can be used to mitigate soil erosion and control dust on construction sites It is also used in wastewater
·Flue gas desulfurization FGD gypsum‐based reclamation of saline‐sodic soil has been widely recognized in the Songnen Plain of China but its reclamation effect depends on water regime
·Salt and sodicity of saline alkali soil adversely affect the construction of ecological landscapes and negatively impact crop production The reclamation potential of biochar BC wheat straw
·SOC stability is the tendency of organic compounds in soil to resist change and/or loss Doetterl et al 2016 The mineralization of OC which controls SOC stabilization versus loss is the dominant pathway of OC sequestration in soil Zhao et al 2022 Grazing modifies the formation and turnover of soil C cycling herbivores induce changes in plant biomass
·Figure 1 a Gypsum crystals produced from sodium sulphate and calcium chloride; b Natural gypsum cut along black lines; c Gypsum crystals from a with directions from Figure 2 marked with arrows on side from Figure 3 marked with yellow on cleavage plane with red; d Crystal from a along c axis marked in black The effect can for
·The results achieved in the LCA showed for the production of recycled gypsum from plasterboard and powder waste a significant improvement more than 40% in all the impact categories understudy as compared to the natural gypsum production Furthermore the results obtained for the endpoint indicators showed an important reduction 56 and 58% of the
·W¼ðÞ8 728 ESPþ0 4412 H D=ðÞ100 η Where H is the soil depth for reclamation m which is m D is the soil bulk density kg m 3 which is 1450 kg m and η is the mass ratio of CaSO
·Soil saline alkalization is a key environmental factor that severely limits the functional roles of soil microbes in arid and semi arid regions globally 1 has been suggested that crop
