Special Issue Information

Dear Colleagues,

The development of metal mineral resources is related to human survival and development, and is an important guarantee of basic materials. However, the metal resources reserved near the earth’s surface are becoming increasingly scarce, and determining how green and smart mining and the disposal of solid mine wastes might be achieved has become a crucial issue. This Special Issue focuses on the underground backfilling of solid mine wastes, surface storage and disposal, rock mechanics, disaster prevention and control in mines, as well as technologies for the development of novel resources such as CCUS and fluidized mining. This Special Issue provides theoretical and technical references for relevant researchers and technicians, and promotes the iterative development of metal mineral resources.

This Special Issue, entitled “Green Mineral Processing and Metallurgy: Resource Recovery, Utilization and Process Optimization”, seeks high-quality studies focusing on topics including, but not limited to, the following: 

  1. Solution mining of low-grade minerals (sulfide copper, uranium, etc.); 
  2. Mechanism and control of mineral processing in metal mines;
  3. Mine waste disposal and utilization, such as backfilling; 
  4. Numerical simulation and visualization of metallurgy procedure;
  5. Mine pollutant control and heavy metal leaching;
  6. Mine seepage mechanics and procedure control;
  7. Green mining safety, methods, and optimization.

It is of great significance to realize the carbonation of Ca/Mg minerals in the basic oxygen furnace (BOF) slag. In this paper, the BOF slag was treated with hydrochloric acid and acetic acid, and the carbon dioxide storage test was carried out. The sample of the BOF slag was treated with acetic acid, in which the content of calcium, magnesium, and silicon accounted for 45.44%, 8.23%, and 6.83%, respectively, and has a BET surface area of 52 m2/g. The thermodynamic analysis results were that the BOF slag can react with carbon dioxide at room temperature to form carbonate. However, better kinetic conditions were needed to obtain the maximum carbon dioxide absorption capacity. The amount of carbon dioxide absorbed by the sample at 25–900 °C was measured. The results showed that in the range of 50–400 °C, the largest amount of carbon dioxide was absorbed by the sample treated with acetic acid, and the absorption amount was between 2.6 and 4.1 mmol/g. In the range of 500–800 °C, the largest amount of carbon dioxide absorbed was lime treated with acetic acid and hydrochloric acid, and the absorption was between 4.2 and 6.0 mmol/g. In the 800–900 °C range, the largest amount of carbon dioxide was absorbed, and the absorption was between 6.0 and 6.9 mmol/g via the samples treated with acetic acid and hydrochloric acid.

The flotation effect of lean coal is crucial for its clean utilization. Therefore, the flotation characteristics of difficult-to-float lean coal were studied. The analysis results of the feed properties showed that the ash content of the feed was high and the particle size was very fine. The minerals in the gangue mainly included sericite, kaolinite, quartz, white mica, and other substances. After flotation, the functional groups of the coal particles in the tailings decreased, and the absorption peak intensity weakened. Furthermore, the results of multi-factor flotation experiments showed that the dosages of the collector and the frother were significant factors affecting the yield of clean coal. The clean coal yield gradually increased with an increase in the two factors. The ash content of the clean coal increased with an increase in the frother dosage. Within the range of feed concentrations used in this work, the feed concentration was not a significant factor affecting the clean coal’s yield and ash content. Prediction models for the clean coal yield and ash content were proposed. Under optimized experimental conditions, the clean coal yield and the flotation perfection index were 72.15% and 46.63%, respectively, indicating a good flotation effect. Full article
