Geological and mining analysis of manganese or in Ispendere (Malatya) region

In this study, it was aimed to determine the chemical and mineralogical features of manganese ore formation in the section numbers of L41-a4 in Malatya Ispendere region and its usage area.Due to optical analysis on the samples taken from the cut-hole points with vein and lenticular distribution, jacopsite, hematite, magnetite, traces of amorpous manganite, manganite, traces of nabit copper (sparingly) were detected in vein-type mineralization, whereas traces of hematite (fine grained-submicroscopic), psilomelan and traces of manganite were observed in lenticular mineralization. XRD studies indicated that mineral paragenesis were mainly hematite, iwakiite/jacopsite, quartz, piyemontit, clay mineral, talc, pyrogenic, serpentine, feldspar and illite/mica mineral groups, amphibole, bixbyite. According to the chemical analysis, the size order of the main oxides were as Fe2O3, MnO, SiO2, CaO, Al2O3, P2O5. Accordingly, the average Fe/Mn was 1,68. Considering natural origin, mineralization was hydro-genetic. As a result of enrichment effort to increase Mn/Fe ratio using wet magnetic separator, Mn/Fe ratio in non-magnetic parts were observed to increase with an increase in gauss intensity.It was concluded that manganese mineralization is economically feasible in Ispendere/Malatya region and can be worked in high grades.
