Dilband iron ore deposits, recently discovered in 1997 by Geological Survey of Pakistan (GSP) in Kalat Division Balochistan, Pakistan, is of major importance from a socio-economical point of view among the indigenous iron ore deposits discovered so far in Pakistan. In order to meet the requirements of Pakistan Steel Mills ore specification (i.e. 57-60 % Fe (min), 8.5 % SiO 2 (max), 0.5 % Al 2 O 3 (max), 0.1 %P (max), and 0.05 % S), the ore requires an adequate concentration method. This calls for detailed characterization of process relevant minerals and their intergrowth. For this reason mineralogical, petrographic, and elemental analysis were performed using XRD, thin section and SEM with EDS, and XRF and Atomic Absorption Spectrometer techniques, respectively. Mineralogical study revealed that Dilband iron ore is mainly composed of 46.27 % hematite, 17.41 % quartz 14.47 % calcite, 9.24 % chlinochlore, 10.5 % kaolinite, and 1.75 % fluorapatite minerals. Atomic absorption analysis of different size fractions ranging from -600 µm down to -38 µm indicated that Dilband iron ore contains on average of 40.18 % Fe, 18.34 % SiO 2 , 5.32 % Ca, and 2.262 % Al. Whereas average analysis of different size fractions on XRF indicated 44.3 % Fe, 20.4 % SiO 2 , 8.8 % CaO, 6.35 % Al 2 O 3 , 1.08 % P 2 O 5 , and 0.065 % SO 3 . Three types of iron stones namely hematiteooides, hematite-peloids, and hematite biosparite were identified from petrographic study. From the mineralogical and elemental analysis data finely dissemination of impurities specially quartz, alumina and phosphorous in hematite phase is conceived, suggesting that Dilband iron ore is not amenable to upgrade with conventional techniques. Mineralogische Beschreibung der Dilband-Eisenerzlagerstätten in Balochistan, Pakistan. Die Dilband-Eisenerzlagerstätten, die erst 1997 vom geologischen Dienst Pakistans in Kalat, Distrikt Balochistan, Pakistan, entdeckt wurden, sind im Vergleich zu den bisher in Pakistan entdeckten Eisenerzlagerstätten aus gesellschaftlicher und wirtschaftlicher Sicht von besonderer Bedeutung. Um die Qualitätsanforderungen des nationalen pakistanischen Stahlherstellers Pakistan Steel Mills (PSM) (i.e. 57-60 % Fe(min), 8,5 % SiO 2 (max), 0,5 % Al 2 O 3 (max), 0,1 %P (max) and 0,05 %S) zu erreichen, muss das Erz mit geeigneter Aufbereitungstechnik angereichert werden. Dies macht die Beurteilung des prozessrelevanten Mineralbestandes und der Verwachsung notwendig. Mineralogisch-petrographische sowie Elementanalysen wurden mittels Röntgendiffraktometrie, Mikroskopie, Rasterelektronenmikroskop mit energiedispersivem Spektrometer sowie Röntgenfluoreszenzanalytik und Atomabsorptionsspektroskopie durchgeführt. Mineralogische Untersuchungen ergaben, dass die untersuchten Proben hauptsächlich aus Hämatit (46 %), Quarz (17 %), Kalzit (14,5 %), Klinochlor (9,2 %), Kaolinit (10,5 %) und Flurapatit (1,75 %) aufgebaut sind. AAS in Kornklassen des Zerkleinerungsproduktes < 600 µm lieferte einen durchschnittlichen Eisengehalt von 40,2 % bei 18,3 % SiO 2 , 5,3 % Ca ...

Industrial CO2 emission mitigation necessitates holistic technology concepts; especially in high‐emission industrial sectors like the iron and steel industry. A novel direct reduction technology with hydrogen reduces CO2 emissions in iron production from siderite ore by more than 60 %. Subsequent valorization of the process gas, consisting of unconverted hydrogen, carbon monoxide, and CO2, by catalytic hydrogenation to methane and methanol completes the technology concept. This route gives access to CO2 emission‐lean iron production from siderite ore, fossil‐free methane and methanol synthesis, and thus, improved energy density of the energy carrier hydrogen.
