Increasing production and disposal of coal fly ash (CFA) is a matter serious environment concern. However, CFA contains various beneficial metals mineral matters whose demand increasing in the industrialized world, while natural supplies are diminishing. Therefore, recovery these potential resources from can be an alternative way to save resources, as well reduce environmental burden disposal. There numerous methods developed for products CFA. Based on US patents journal literatures, present...
The coal fly ash (FA), mainly containing high unburnt carbon was modified by alkali hydrothermal treatment. (MFA) contains lower amounts of Si and Al has a higher surface area pH than the untreated (FA). objective this study is to investigate potential MFA as low cost adsorbent material for removal Al, Fe, Ni, Pb, Zn Mn from acid mine drainage (AMD). effect dose, contact time competing cations on adsorption metals investigated. results showed that sorption process onto initially rapid, but...
A hierarchical CuS/Bi<sub>2</sub>W<sub>2</sub>O<sub>9</sub> heterojunction photocatalyst exhibits excellent photocatalytic activity for the degradation of diuron achieving 95% mineralization within 3 h irradiation.
The SARS-CoV-2 (or COVID-19) lockdown in India, which started at an early stage of its infection curve, has been one the strictest world. Air quality improved all urban centers a major emitter greenhouse gases (GHG). This study is based on hypothesis that abrupt halt activities resulted massive decline NO2 emissions and also altered coastal nitrogen (N) inputs; in-turn, this affected trophic status waters across country. We present first evidence overall pre-monsoon chlorophyll-a, proxy for...
The estimation of sediment yield is important in design, planning and management river systems. Unfortunately, its accurate using traditional methods difficult as it involves various complex processes variables. This investigation deals with a hybrid approach which comprises genetic algorithm-based artificial intelligence (GA-AI) models for the prediction Mahanadi River basin, India. Artificial neural network (ANN) support vector machine (SVM) are developed prediction, where all parameters...
Open pit mine production scheduling is a computationally expensive large-scale mixed-integer linear programming problem. This research develops efficient algorithm to solve open problems under uncertain geological parameters. The proposed solution approach for two-stage process. stochastic problem iteratively solved in the first stage after relaxing resource constraints using parametric graph closure algorithm. Finally, branch-and-cut applied respect constraints, which might be violated...
The Mahanadi river basin (MRB) is one of the eight major fluvial basins India. This paper presents a very first systematic study geochemical characteristics, including rare earth elements surface sediments collected from riverbed at different parts this to infer chemical weathering, provenance, and tectonic settings. Lower mean values (except for SiO 2 K O) are observed compared with that upper continental crust (UCC). It attributed dominance quartz orthoclase in removal mobile sediment...
The mineralogy and trace element contents in coals from the West Bokaro coalfield, which is one of biggest Gondwana coalfields India, were studied to delineate enrichment elements their modes occurrence. Elemental concentrations with reference crustal abundances indicated that are relatively enriched As (4.4–15.5 mg/kg), Cd (0.3–3.0 Cu (28.0–68.1 mg/kg) V (46.6–178.0 mg/kg); depleted Co (10.8–28.4 Mn (7.6–483.4 Ni (13.0–31.6 Cr (14.2–85.5 Zn (5.25–70.4 mg/kg). concentration As, Cd, Co,...
