At the current stage of development, transition to a circular economy is single option achieve sustainable mining. Purpose was identify direction for mining tailings usage based on waste management. The novelty author's approach lies in regulation mechanical treatment slag optimize backfill composition. methodology involved study (slag) obtained from major (eight) metallurgical plants Russia. For mathematical processing primary data, smoothing and deterministic three-dimensional interpolation methods were used. As result, first time it has been established that ultimate uniaxial compressive strength after increases by logarithmic laws. curing 10 days 90 (with addition Ca or Si) 21 % (7 23 %). possibility completely replacing traditional cement binder with composite proven. It use activation (both chemical) makes possible increase characteristics samples their curing. principle organizing production implemented, which provides intermediate products (blast furnace granulated slag), previously classified as technogenic waste, closed cycle. introduction this will eliminate (minimize) formation man-made waste. scientific merit slag) allows implementation

This work is aimed at the analysis of development flotation technology by applying carrier minerals. Based on concepts continuum mechanics, a theoretical influence minerals (wall) motion single solid particle provided, taking into account their hydrodynamic interaction (in case low Reynolds numbers). A correction was obtained in form ratio size to its distance from wall take force acting particle. The manifested through rapid approximation liquid vortex flow gap between and steady-state mode, accompanied suppression transverse movement particles. When slides along wall-mounted gas–liquid layer with reduced viscosity, increases interfacial gap, which can be analyzed dimensionless that includes values describing properties continuous medium (dynamic viscosity) disperse phase (geometric size). reason for decrease induction time when gold grains adhere each other assumed due forces hydrophobic attraction (when have mirror-smooth surface) sliding surface particles gas rough surface). polydisperse are aggregated, threshold energy fast coagulation established lower than arising during monodisperse particles, whose aggregation requires large depth potential pit.

Groundwater quality is vital for public health, agriculture, and industry, especially in regions like Telangana, India. This study analyses predicts post-monsoon 2020 groundwater using data from the Telangana State Department. We employed Linear Regression Random Forest to predict key parameters: pH Total Dissolved Solids (TDS). Exploratory analysis revealed significant correlations, such as between TDS Electrical Conductivity (E.C). The model performed exceptionally well, with an R 2 of 0.985, while also showed strong results. However, both models exhibited moderate accuracy predicting pH. demonstrates effectiveness machine learning quality, offering valuable tools management. These findings can aid policymakers environmental managers making informed decisions safeguard water resources.

Ensuring access to safe drinking water is a fundamental public health priority. Traditional methods for assessing quality are laborintensive and require specialized equipment, which may not be feasible continuous monitoring. This study explores the use of machine learning models predict potability based on various chemical properties. Specifically, we evaluate performance Logistic Regression Random Forest in presence class imbalance, common issue environmental datasets. To mitigate this, apply Synthetic Minority Over-sampling Technique (SMOTE). Our results indicate that before applying SMOTE, both exhibited strong bias towards majority (non-potable water), achieving an accuracy 69.36% ROCAUC 0.63. However, application SMOTE significantly improved model’s ability identify potable samples, particularly model, achieved 67.07% 0.64 post-SMOTE. In contrast, model showed decline after suggesting need further optimization or alternative approaches. highlights importance addressing imbalance tasks, especially critical applications like assessment. findings suggest combined with offers robust solution predicting potability. These insights can aid scientists officials implementing more efficient accurate monitoring systems. Future research should explore broader range advanced techniques enhance prediction accuracy.
