Manganese ore

The MineDop manganese ores are pyrolusite, manganite and psilomelane and comes from various mine sites and are subjected to process which crushing, classification and beneficiation. The final products have concentration of Mn at %30-%50 and have various particle sizes and spesifications for the customer demands.

The MineDop manganese ore’s main characteristics include a high grade of manganes depending customer demands and wide grain size distribution and high degree of oxidation of the ore which makes it possible to decrease energy consumption and provide the yields during its use.

Main chemical spesifications are;

Mn %31-%52
Fe %0,61-%0,7
SiO2 %20,3-%24,6
P %0,073-%0,075
S %0,032-%0,051
Ba %0,0021-22

Manganese is the 4th most used metal in terms of volume and is mainly used forthe iron and steel production to increase the mechanical properties of steel. It is used in the process itself and directly participates in the composition of many alloy grades.

Nearly all steels contain manganese, in a proportion ranging between 0.05 and 2%, Manganese increases the yield strength, hardness and wear resistance of steels . Manganese also provides the work of steel , preventing cracking during forming or hot rolling. Manganese steel has a high resistance versus corrosion. It is mainly used for the produce of rails and switches in bearings or for safes.

Manganese,has many other applications. It is used for the paint and its additives, manufacture of batteries and batteries, for some ceramics and glass processes, but also in agriculture (fertilizers and animal feed) or in metallurgy (hardener for aluminum) and in chemistry as a portable and electronic energy and agricultural additive.

Silico Manganese

SiMn is produced by a mixture of manganese ores, coke, quartz and dolomite in an electrical arc furnaces thanks to pyrometallurgical processes which have steps such as preperation, drying, monitoring, feeding and shaping.

Main spesifications are;

SiO2% 29 – 32
MnO% 25 – 30
Al2O3% 1.0 – 3.0
CaO% 3.0 – 8.0
Fe2O3% 1.0 – 3.0

Ferro Silico Manganese

FeSiMn can be used as composition of deoxidant, desulphurizer and alloying addition in steel making and as a reductant in medium-low carbon iron production or in metal manganese production.

Main Spesifications are;

MANGANESE 65 - 68 %
SILICON 16 - 18 %
CARBON 2.0 - 2.5 % MAX
PHOSHOROUS 0.10 - 0.30 % MAX
SULPHUR 0.02- 0.04 % MAX

High Carbon Ferro Manganese

HCFeManganese has an important influence on the structure and properties of steel, depending on the amount used and the combined effect with other alloying elements. Manganese improves the tensile strength, workability, toughness, hardness and resistance to abrasion. It also reacts with the remaining sulphur in the steel, thus preventing hot shortness.

Main Spesifications are;

MANGANESE 75 - 78 %
SILICON 1 - 2 %
CARBON 6 - 8 % MAX
PHOSHOROUS 0.10 - 0.30 % MAX
SULPHUR 0.02 - 0.04 % MAX

Manganese Oxide Briquettes

The fine particles can be briquetted into larger particles so that will improve permeability of furnace burden and reduce the amount of material blown out of the furnace as fines. Manganese briquettes provide accuracy and sensitivity for production of manganese ferro alloys and elemental manganese.

Our manganese oxide briquettes have main properties. These are;

Mn Min. 56%
P Max. 0,07%
S Max 0,03-%0,04%
Ba 0,002%


MineDop Baryte production is consists of two quality classes.
1. Paint grade baryte:
Density :4.2 gr/cm3
Whiteness : %90 minimum
high brightness, high purity, and fine particle size

2.Paint grade baryte (quality conforms to OCMA Standart Baryte):
Density : >4.2 gr/cm3
Whiteness : %90 minimum

The commercial significance of barite is related almost entirely to its high specific gravity. Most processed barite (90%) is used as a weighting agent in well drillling fluids. Its physical and chemical properties assume more importance for its filler applications and for its use as a source of barium. Common mineral impurities in barite ores are quartz, carbonate minerals, sulfide minerals, and clay. Processing of barite depends upon ore purity and the nature of associated minerals. Drilling grades often require only crushing, grinding, sieving, and milling. An intermediate washing step may be employed to achieve required minimal specific gravity and BaSO4 content.

Applications requiring high brightness and high chemical or mineralogical purity may necessitate flotation, bleaching with sulfuric acid, and wet grinding. Barite is also known as barytes and heavy spar. It is used as a source of bariuim in a number of barium compounds, including blanc fixe, a high-purity precipitated barium sulfate that is used in place of processed barite in certain demanding applications. Other than drilling fluid products, which account for most of production, bariteis differentiated according to its chemical and filler uses.
