Iron and manganese ores are the basic raw materials of the
iron and steel industry. Apart from steel production, they
are used in the production of batteries, glass, fertilizers,
food additives, pharmaceuticals, chemicals and fireworks
[1-3].
Turkish manganese deposits are divided into four main
groups as Hydrothermal-hydrogenetic, black shale-hosted,
occurring in metasomatic, hydrothermal, landlocked
environments, and the ores hosted in oligocene. The
manganese iron ores subject to the study are among the
first group of manganese deposits. Spilite, limestone
and outcrops are seen in the environment. Spilites are
separated in places. The limestone coarse grained and
layered structure overlying the spilites can be seen on rare
faces. Spilites were exposed in the dry stream bed and
where there was no outcrop accumulation. It affected the
sedimentary ore together with the spilites with the thrust in
the northwest-southeast direction and from the northwest
to the southeast, and some fractures were caused by small
faults [4]. The selected ore samples were dissolved in aqua
regia. Then the solutions were analysed by AAS (Atomic
adsorption spectrofotometer). The results show that they
contains approximately 25% Fe and 15% Mn. The mineral
phases were determined by Bruker Discover D8 XRD
(X-Ray Diffractometer) device. It has been determined that
the crystal phase consists of hematite, goethite, manganite,
maghemite, garnet, quartz, calcite, rhamsdellite and
magnesium calcite minerals (Figure 1).
EDS analyzes were performed with the Zeiss Gemini 300
brand scanning electron microscope (SEM) using a dust
sample under 100 μm particle sizes. The sem image and a
point EDS analyses were shown in Figure 2.
XRF (X-Ray Fluoresences) analyzes were also carried out
and it was determined that the results confirmed the XRD
and chemical analysis. According to the classification of the
Indian Mining Bureau, it has been determined that the ores
belong to the manganese iron ores class [5].
Detailed information about the usage areas and production
process of the ore were highlighted and its characterization
was carried out.
