Table 1 shows as a major example the summary of the metal contents of various tailings from some of the existing and historic metal mines in Finland. The tailings contain for example nickel, cobalt and zinc. ... involving the reaction of atmospheric CO 2 with unstable silicates such as olivine, wollastonite ... the potential of data generated ...

Initially, the tailing sample's pH was 8.4-9.7 and decreased to 7.7-9.1 over the 18 weeks. Soil additions lowered the initial pH and converged with the tailing's pH over 18 weeks.

concen trate, while most of the serpentine was foun d to be in the tailing. Due to the low olivine conten t . of the Ye silova-Burdur chromite tailings, ... As shown in Tables 3 and 4, TV and VIF ...

The mining industry generates vast quantities of mine tailings on an annual basis. However, due to their limited economic value, a significant portion of these tailings are deposited close to mining sites, often underwater. The principal environmental apprehensions associated with mine tailings revolve around their elevated levels of heavy metals and sulfidic minerals. …

The specific surface area of the powdered ilmenite and olivine were determined by a N 2 adsorption analysis by a Micromeritics ASAP 2010C instrument and were found to be 1.25 m 2 /g and 2.17 m 2 /g, respectively. Chemical composition analysis (Table 1) and X-ray diffraction (XRD) (Fig. 1) were used to

This heavy liquid separation study indicates that the quantity of lighter minerals is 28.17% in the tailing (Table 2). It is also reported that the content of low-density minerals decreases with particle size. ... (< 300 μm), and the associated minerals are goethite and Fe silicates such as olivine, pyroxene, etc. It was concluded that silica ...

This "tailing" phenomenon is commonly attributed to a joint operation of a fast diffusion mechanism and a slow one (Moore et al., 1998, ... respectively, both studied in experiment ZL34; Table 1). The olivine samples also displayed strong Li diffusion anisotropies of 1.2 and 1.4 log units, respectively (Table 2). ...

criterions" in the between of chromite, olivine and serpen-tine, there are 1.44 for olivine & serpentine, 1.56 for chro-mite & olivine and 2.25 for chromite & serpentine. Because of chromite mineral has higher specific gravity than olivine and serpentine minerals, concentration of the chromite min-eral is easy.
