Argane et al., [46] reported a silt sized tailing of D 50 210-270 µm whereas Bussiere [28] reported a cement sized mine tailing of D 50 17 µm. The particle size distribution of mine tailing ...

Fluorite is an important strategic mineral. In general, fluorite ores will contain a certain amount of calcite gangue mineral. Thus, they need to be separated from each …

Approximately 55% of tailing sand particles have a particle size ≤19 μm, while about 18% particles have a size of ≥74 μm. Therefore, the tailing sand has fine particles that exhibit good water-retention performance. In addition, the uniformity and curvature coefficients are used to evaluate the gradation excellence of the tailing sand.

Mine tailing particles are angular, resulting in a high friction angle of dry tailings. ... (OH) 6), calcite, and dolomite [129]. The most frequent sulfide minerals found in ores include pyrite, pyrrhotite, chalcopyrite, arsenopyrite, sphalerite, and galena, which are likely to be found in mine tailings. ... As indicated in Table 5, Table 6 ...

Particles with diameter between +0.038 mm to −0.074 mm were obtained after wet sieve. Both bastnaesite and calcite samples were dried over at 40 °C vacuum oven. The chemical composition and X-ray diffraction pattern (XRD) measurements of bastnaesite and calcite are shown in Table 1 and Fig. 1. The results indicated that the samples with high ...

This study examines a sustainable technique known as Microbially-Induced Calcite Precipitation (MICP) to improve the static liquefaction resistance of gold mine silty sand tailings. ... Table 1 summarizes the DSS tests carried out in this study. ... (to about ε vol < 2%) as a result of the stiffer (cemented) tailing's structure. Download ...

A series of characteristics of the two tailing samples are listed in Table 1. From the table it can be seen that the main differences in composition are calcite content (higher in MT 2), free chalcopyrite content (higher in MT 2), and magnetite content (higher in MT 20). The last is an indication of the ongoing oxidation of the tailings.

The chemical compositions of the smithsonite and calcite mineral samples are listed in Table 1, further confirming the high purity of the as-prepared mineral samples.

As an anionic collector, fatty acid is widely used for fluorite flotation in industrial production [5], [6], [7].However, efficiently separating complex associated fluorite from calcium-bearing gangue minerals is difficult due to the poor selectivity, low solubility and low temperature resistance of anionic collectors [8].The separation of complex associated fluorite and calcite is …

Mining activities offer clear economic benefits for mineral-rich countries. However, mining operations can produce several environmental impacts. Many of these are associated with generating and managing mining waste known as tailings, which are typically stored in surface facilities. Windblown dust emissions from tailing deposits can cause severe damage to local …

Primary minerals identified in tailings include arsenopyrite, galena, calcite, sphalerite, sylvanite, beudantite, and quartz (Mendez and Armienta, 2003; Zúñiga-Vázquez et al., 2019).

As shown in table 3, the -Q int values for the reaction between Al 2 (SO 4) 3 and celestite, calcite and fluorite are 1.25 J g −1, 0.656 J g −1 and 0.849 J g −1, respectively, indicating that the interaction between Al 2 (SO 4) 3 and celestite is …

Despite consisting largely of non-reactive silicates and primary calcite, very fine tailings showed promise in closed-chamber batch-type aqueous carbonation, achieving a conversion extent of over 28% in one hour at 100 bar and 60 °C.

Here, we aimed to stabilize acid-generated mine tailings using several alkaline and cementitious amendments, which were tested in columns for 361 days. The alkaline amendments consisted of 10 and...

Quartz was the most dominant mineral crushed during the mining process from gangue and/or rock-forming minerals from quartz vein and host rock in the study area [50,51] (Table 2). Calcite ...

The calcite zeta potential showed a negative shift of 28.9 mV (Figure 6 b), greater than the 15.2 mV measured in the case of scheelite (Figure 6 a). This revealed that SMKL adsorption on calcite had a higher intensity compared to scheelite. The addition of NaOL decreased the calcite zeta potential to only 3.6 mV.

The sorption maximum of calcite was 26 mg P kg −1. This result was used to calculate the surface coverage of calcite by sorbed P. The model indicated that only 1 4 to 1 8 of the unit cell surface was able to adsorb phosphate. High-gradient magnetic separation (HGMS) was used to fractionate soil clays into magnetic and tailing fractions.

Like tables, you often want to query streams in a high-level language based on relational algebra, validated according to a schema, and optimized to take advantage of available resources and algorithms. Calcite's SQL is an extension to standard SQL, not another 'SQL-like' language. The distinction is important, for several reasons:

In this paper, a new inorganic method of inducing tailings cementation is introduced which uses a naturally occurring mineral called trona (Na2CO3•NaHCO3•2H2O). Three methods of …

Fluorite is usually associated with quartz, calcite, barite and sulfides (Magotra et al., 2017, Schubert et al., 1990).Due to the similar density, magnetic properties, electrical conductivity and dielectric constants of fluorite and its associated minerals, effective separation of fluorite and associated minerals cannot be achieved using gravity, magnetic and electrical separation …
