The extensive use of coal in the steel metallurgy sector has resulted significant greenhouse gas emissions. Hydrogen-rich gases have been introduced to partially replace blast furnace reduction process mitigate this issue. This research explores using abundant coalbed methane (CBM) resources near plants for metallurgical applications. Addressing challenge determining optimal parameters hydrogen-rich smelting, project first develops an energy and mass balance model furnace, providing a...
A novel approach for recovery of iron and rare earth elements (REEs) from Bayan Obo tailings Baotou, China, was developed by combining magnetizing roasting, magnetic separation, (NH4)2SO4 activation water leaching. Thermodynamic analysis carbothermal reduction conducted to determine the temperature it agreed well with experimental results. The maximum Fe reached 77.8% at 600 °C, grade total in concentrate 56.3 wt. %. An innovative approach, using leach REEs after used extract separation...
In this work, the carbothermal reduction and hydrochloric acid leaching were utilized for separation recovery of iron rare earth from Bayan Obo tailings. The effects temperature, addition calcium oxide, reaction time on metallization rate during roasting investigated. results showed that reached 99.67% loss fluorine was less than 1% under optimum conditions a temperature 1100 °C, coal ratio 6.77 wt %, oxide 10 2 h. behavior in magnetic found to be controlled by particle size after grinding....
Abstract SnO 2 /BiOBr photocatalyst with broad‐spectrum response was one step constructed via in situ hydrothermal method; anchored on the surface of BiOBr sheets by acidolysis Na 3 stock solution producing BiOBr. The photocatalytic degradation activity over rhodamine B (RhB) under visible light‐emitting diode irradiation is further improved coupling a 7% amount . reaction rate constant 7%SnO 8.2 times that pristine enhanced performance can be ascribed to excellent adsorption abilities for...
The dynamic, multiscale nature of stream systems makes it challenging to establish basic ecological principles guide fish conservation and management. For example, finer-scale instream habitat is often constrained by coarser-scale characteristics driving observed species distributions. Additionally, environmental variability can result in patchy distributions within general upstream–downstream occurrence patterns (i.e., variation around a common theme). Groundwater contribution, an...
Abstract Soil pipes are important subsurface flow pathways in many soil erosion phenomena. However, limited research has been performed on quantifying and characterizing their transport characteristics. The objectives of this were to determine the applicability a streamflow model with transient storage deriving characteristics pipes. Tracer data from pulse inputs collected four different after fluorescein dye was injected upstream end each pipe network three branches (west, middle, east)...
The roasting method of magnetic tailing mixed with CaO and coal was used to recycle the rare earth elements (REE) in tailing. phase transformation decomposition process were researched during processes. results showed that processes REE divided into two steps. first step from 380 431 °C mainly entailed bastnaesite (REFCO3). second 605 716 included monazite (REPO4). products primarily RE2O3, Ce0.75Nd0.25O1.875, CeO2, Ca5F(PO4)3, CaF2. Adding could reduce temperature REFCO3 REPO4. Meanwhile,...
The alkali and alkaline earth metals in the biomass are one of major challenges that restrict biomass/low-rank-coal entrained-flow gasification way ash slagging corrosion.

A heterojunction Al2O3/BiOBr composite photocatalyst, characterized by an S-scheme structure and enriched with oxygen vacancies, was synthesized through a solvothermal reaction coupled in situ growth approach. The presence of vacancies on the catalysts' surface, enhanced robust coupling between Al2O3 BiOBr, corroborated X-ray photoelectron spectroscopy (XPS) electron paramagnetic resonance (EPR). Techniques such as UV‒vis diffuse reflectance (DRS), UV (UPS), Mott–Schottky characterization,...
