Nickel-containing electroplating sludge is a solid waste generated during the treatment of wastewater, often managed through solidification with materials such as cement and lime. This paper presents novel approach for solidifying nickel-containing using basic metallurgical waste. A mathematical model was employed to determine kinetics Ni2+ leaching, yielding kinetic equation α(t) = 0.97*(1-exp(-0.19*t)). Rapid leaching occurred in initial 10 minutes, reaching concentration 86.78 mg/L,...
The monitoring of sintering bed temperature is crucial for controlling physical and chemical reactions during the process achieving low carbonization trends. However, accurately this challenging due to "black box" nature bed, which includes trolley cup. As a result, theoretical model needs be developed urgently predict bed's profile. In investigation, we propose mathematical that utilizes characteristic value lognormal distribution estimate indirectly based on measured exhaust gas. gas...
The sintering process is influenced by complex low-grade ores. This study used seven types of imported iron ore, A–F and domestically produced G, as raw materials to their chemical composition, well the liquid fluidity bonding strength mixed ore after single optimised blending. high-temperature characteristic test values ores are positively correlated with weighted calculated individual Under cup conditions, optimal mixing includes a 9% increase in 6% strength. latter significantly improved...
A three-dimensional numerical model of the rock mass including ore body is established by FLAC3D software, and then surface subsidence caused backfilling under different roof thicknesses mining stope (the vertical distance between upper limit surface) are calculated analyzed. By comparing displacement, stress distribution, damage zone conditions, minimum thickness determined.
Nickel-containing electroplating sludge is a significant solid waste generated during the plating process, which often solidified using cement, lime, and other materials. This paper presents novel approach for solidifying nickel-containing typical basic metallurgical waste: sintering dust steel slag. study systematically investigated influence of dosage types agents on solidification process its resulting products. The leaching concentration, element distribution, chemical composition,...
The electroplating sludge is a solid waste containing transition metals, typically treated using thermal processing and solidification landfill methods, with limited emphasis on resource utilization. This study aimed to prepare as iron-nickel oxygen carriers (FeNi-OCs) for catalytic denitrification. research analyzed the phase composition, microstructure, elemental valence changes of FeNi-OCs during reduction NO by CO, well pathways denitrification catalyzed FeNi-OCs. results revealed that...
