“…Yttrium is an important rare earth element 5 and is used in fields such as special glass preparation, 6 metallurgy, 7 and materials science. 8 As a nonrenewable rare earth, the scale of yttrium use has continuously been reduced by extensive development and utilization. 9 According to statistics, mining wastewater (including coal mine drainage) contains a large amount of low concentration rare earth ions, which have been explored as an attractive secondary source for rare earth recovery.…”

“…Yttrium is used extensively in a variety of fields, including metallurgy, electronics, ceramics, laser technology, and fluorescent materials. Yttrium (Y) and lanthanides always coexist in rare earth minerals due to their similar chemical characteristics, especially in the ion-adsorption type rare earth deposits [9]. One of the most significant REEs, Y, is also the second most common REE in the crust of the earth after cerium.…”

From the analysis of zircon tailings using X-Ray Fluorescence (XRF), Yttrium is a rare earth element (REE) with the highest concentration compared to other REEs. The purpose of this study is to determine the best kinetic model for describing how sulfuric acid extracts Yttrium from zircon tailings. Leaching temperatures of 200, 250, and 300 °C were used to determine the kinetics. Samples were obtained at 0, 20, 40, 60, 80, 100, and 120 min for each temperature. This study discovered that the chemical reaction model's kinetics are the most closely related to those of the leaching process. The evaluation of the model utilizing the coefficient of determination (R2) on the relationship between each model and time lends support to this conclusion. The activation energy (Ea) of the leaching process is determined by the Arrhenius plot between ln k and 1/T. In the Yttrium leaching procedure, the Ea value is 14.42 kJ/mol. The chemical reaction model was in charge of the leaching process, according to the Ea value. The premise of the chemical reaction model is that chemical reactions regulate the rate of the reaction.

Improving the green mechanical strength of colloidal silica‐bonded corundum castables is essential to their widespread utility. The effects of varying contents (0∼2 wt%) of La2O3 on the green mechanical strength of colloidal silica‐bonded corundum castables were investigated. The findings demonstrate that La2O3 has a positive impact on the green mechanical strength of colloidal silica‐bonded castables. The colloidal silica‐bonded corundum castable containing 2 wt% La2O3 exhibits higher green mechanical strength than the cement‐bonded corundum castable. Additionally, the castable shows excellent construction performance. The basic properties of La2O3 and La(OH)3 facilitate the absorption of H+ from the surface of colloidal silica to form more siloxane bonds and speed up gelation. FTIR and XPS analyses indicate that La3+ ions participate in the condensation of ‐Si‐OH and bond the broken Si‐O bonds to create Si‐O‐La chemical bonds. La3+ ions bridge the colloidal silica particles, leading to stable three‐dimensional network structures that result in an increased green mechanical strength of the castables. The water consumption during the hydration reaction expedites gelation, further contributing to the enhancement of the green mechanical strength of the corundum castables. Given its wide sources and stable performance, La2O3 can be considered an efficient setting agent with the potential for extensive industrial application.This article is protected by copyright.
