Production of high carbon ferromanganese from a manganese ore located in Erzincan

Çardaklı, İsmail Seçkin
Main purpose of this study was to investigate the production of high carbon ferromanganese by smelting a manganese ore located in Erzincan. Time, charge basicity, fluorspar addition and coke to ore weight ratio were used as experimental variables. After characterization of the ore, a mixture of 100 grams of uncalcined manganese ore and carefully weighed amounts of coke powder, lime, fluorspar and scrap iron were put into a conical graphite crucible. The graphite crucible with its contents was covered with a graphite lid and placed in an electronically controlled muffle furnace. The furnace was heated to 1600 oC and held at this temperature for a predetermined time and cooled to room temperature. The crucible was taken out of the furnace and the metal and slag phases formed were removed from the crucible by breaking the crucible and carefully weighed. Finally, the metal and slag phase were subjected to chemical analysis. The experimental results show that Erzincan manganese ore can be used in the production of high carbon ferromanganese.


Optimization of conditions to produce manganese and iron carbides from Denizli-Tavas manganese ore by solid state reduction
Akıl, Cem; Geveci, Ahmet; Department of Metallurgical and Materials Engineering (2007)
Main purpose of this study was to find the optimum conditions to produce a charge material for ferromanganese production or steelmaking with high content of iron and manganese carbides from Denizli-Tavas manganese ore by carbothermic reduction and investigate the effects of temperature, time, amount of active carbon addition and CaO addition on this reduction. The ore was calcined and then mixed with active carbon and CaO. Experiments were performed in a horizontal tube furnace that can be heated up to 1700...
Production of precipitated calcium carbonate from marble wastes
Sezer, Nurettin; Arol, Ali İhsan; Department of Mining Engineering (2013)
The aim of this study was to investigate the production of precipitated calcium carbonate from marble wastes. Limestone is used as the source for the production of precipitated calcium carbonate. Marble wastes primarily constitute of CaCO3. As the major content of the marble waste and limestone are the same, marble wastes can be used as an alternative source for the production of precipitated calcium carbonate. By this way, both the adverse environmental effects of marble wastes can be prevented and the was...
Recovery of germanium and other valuable metals from zinc plant residues
Kul, A.; Topkaya, Yavuz Ali (Elsevier BV, 2008-06-01)
The main purpose of this study was to characterize and to extract germanium from the copper cake of Cinkur Zinc Plant. The physical, chemical and mineralogical characterization of the ground copper cake sample obtained from Cinkur showed that it was 84% below 147 pin containing 700 ppm germanium. The copper cake also contained 15.33% Cu, 15.63% Zn, 1.66% Cd, 1.33% Ni, 0.64% Co, 0.35% Fe, 2.62% Pb, 12.6% As, 0.18% Sb and 3.42% SiO2. The mineralogical analysis indicated the complex nature of the copper cake w...
Distribution of dissolved and particulate forms of iron and manganese in the Black Sea
Erdoğan, Selahattin; Yemenicioğlu, Semal; Department of Marine Sciences (2002)
The principal aim of this study is to examine the behavior of dissolved inorganic and particulate forms of manganese and iron compounds in the oxic/anoxic transition (suboxic) zone of the western cyclone and coastal margin of the Black Sea. The samples were collected from the stations visited during three cruises of RV/Bilim at July 2000, September 2000, July 2001 and RV/Knorr at July 2001 in the Black Sea. In addition, real time profiles of dissolved Mn and Fe(ll) were obtained using a continuous profiling...
Determination of kinetic parameters of different origin coals using software
Ertunc, Goker; Kök, Mustafa Verşan (2015-02-01)
In this study, combustion characteristics and kinetics of three coal samples are examined. A series of thermogravimetry (TG-DTG) and differential scanning calorimetry (DSC) measurements were carried out in non-isothermal conditions at heating rates of 5, 10, and 15 K min(-1). Reaction regions, peak and burn-out temperatures, mass loss, and heat of reactions of the samples were determined for each heating rate from TG-DTG and DSC curves. A variety of computational methods, available in the software developed...
