The barite recovery process can be considered as a separation of two solids One the light solids composed of formation and added solids has a specific gravity of to ; the other barite has a specific gravity of to This density difference plus the fact that the average light solids particle size is much smaller than the
Barite ores are generally evaluated in less than 10 gravity based concentration plants facilities established as jigs and shaking tables in different regions of Turkey During the barite concentration in these concentrator plants an important amount of very fine barite minerals escapes in the tailing fraction
·Table 1 presents the analysis of the mineral phase content of the three minerals obtained by Advanced Mineral Identification and Characterization System AMICS The table shows that after the strong magnetic separation of rare earth tailing the main mineral types did not change but the relative content of some minerals changed
· Chemical Analyzes Results of the Tailing According to the chemical analysis results presented in Table 3 this amalgam tailing contains more than 90% SiO 2 by weight The contents of other major elements such as TiO 2 MnO MgO and CaO are very low The contents of trace elements such as Cu 191 ppm Pb 215 ppm As 189 ppm Ba 155
·In the tailing the recovery o f barite was % with a grade of % Obviously the effectual separation of fluorite from barite is possible using MS
·Barite is a critical mineral that finds applications in many industries Table 1 shows the different barite deposits and examples Michele 2022 Griffith and Paytan 2012 Hammarstrom et al 2022 Bedded sediment hosted deposits are massive Resources and production of barite and the CaF 2 grade and recovery in the tailing reached

Sustainability 2021 13 12982 3 of 21 and Africa is to be carried out by local investor backed companies following environmental best practices However barite like any other minerals of
The chemical compositions of the associated minerals in the barite tailing were determined by an XRF method as shown in Table 1 As expected the tailing is mainly composed of SiO 2 Al 2 O 3 and CaO Table 1 Chemical compositions of barite tailing Components SiO 2 Al 2 O 3 CaO Fe 2 O 3 MgO SO 3 Na 2 O K 2 O BaSO 4 LOI
·From Table 1 it can be deduced that Kiana Barite ore contains % BaO and % SO 3 The main undesirable gangue impurity is silica On the other hand the chemical analysis of the tailing revealed that it contains % BaO This obtained assay indicates appreciable barium oxide content in the tailings Therefore there is a need to
·Barite in the examined samples is present in amounts from about 2 to over 40% The amounts were mineralogical documented Fig 1 and confirmed by barium numbers in the examined sediment samples Table 2 Examples of diffractograms with different barite content in sediments from underground water are shown in Fig 1
