The rapid and accurate quantitative analysis of the total iron (TFe) content in iron ores is extremely important in global iron ore trade. Due to the matrix effect among iron ores from different origins, it is a major challenge to accurately determine the TFe content of iron ores by laser-induced breakdown spectroscopy (LIBS).

Most of the vanadium in the ore is isomorphic with iron minerals and enters the iron concentrate during ore dressing processes. Table 4.7 shows the occurrence of Fe, V, and Ti in different deposits in the Panzhihua region (China).
Vanadium titanomagnetite, which contains the valuable elements iron, vanadium, and titanium, is a complex iron ore. Although it widely distributed throughout the world, concentrations thereof are mainly found in Russia, China, South Africa, and the United States.1 The Panzhihua region of China has rich vanadium titanomagnetite …
For titanium iron concentrate in Panzhihua, the content of iron is about 50%, and the content of TiO 2 is about 12%. Three process methods, namely the Blast Furnace iron making process, the rotary kiln-electric furnace process, and the reduction-magnetic sepa-ration process, dominate the titanium iron concentrate utilization industry in China.
In order to investigate how Fe was enriched from parental high-Ti basaltic magma to form the stratigraphically thick Fe-Ti oxide ore at the bottom layers, we present a systematic study for Fe isotopic compositions of whole rocks and mineral separates (clinopyroxene, magnetite, and ilmenite) throughout the Panzhihua intrusion.
Panzhihua, as one of the four major iron ore regions in China, is rich in mineral resources. Seventy-six types of minerals have been discovered, and 7.18 billion …
Magmatic iron deposit, occurring in Panzhihua layered intrusion, is one of the most important iron resources in China and builds up Emeishan mantle plume. However, …
Study area. Panzhihua is located in the southwest of Sichuan Province, China, latitude 26° 05′ ~ 27° 21′ N and longitude 101° 08′ ~ 102° 15′ E. Based on the distribution of industrial factories and mines in the city, we divided the study area into five different zones: (1) PG: with an iron ore smelter, effected by iron ore smelting; (2) FC: …
The ∼ 2-km-thick Panzhihua gabbroic-layered intrusion in SW China is unusual because it hosts a giant Fe–Ti oxide deposit in its lower zone. The deposit consists of laterally extensive net-textured and massive Fe–Ti oxide ore layers, the thickest of which is ∼ 60 m. To examine the magmatic processes that resulted in the Fe enrichment of …
The hydrogen-rich reduction of ilmenite concentrates has a significant effect on the reduction of the carbon footprint of the titanium slag production process. This study investigates the hydrogen-rich reduction of Panzhihua ilmenite concentrate pellets. The pellets were roasted at 500, 700, 900, and 1100 °C and used as the raw material for the …
The Panzhihua intrusion is a ∼ 19-km-long and 2-km-thick gabbroic sill with a SHRIMP U–Pb zircon age of 260 ± 3 Ma (Zhou et al., 2005) (Fig. 2).It concordantly intruded Late Neoproterozoic dolomitic limestone (the Dengying formation) and formed a contact metamorphic aureole composed of marble and skarns along the lower intrusive margin …
characterizes the compositions, ore textures, minerals, and particle size of the VTM in the Panzhihua region using a variety of techniques, including MLA, EPMA, SEM, and XRD. The results from this study are expected to provide guidance for the efficient separation of ilmenite and titanomagnetite. 2. Ore Characteristics 2.1. Ore …
It is the third largest iron ore producing region after Anshan-Benxi and East Hebei. The ore is Panzhihua type which has high vanadium and titanium(V-Ti) content …
As one of China's four major iron-producing regions, Panzhihua has a substantial amount of vanadium-titanium magnetite resources, including 7.18 billion tons of proven iron ore that accounts for ...
These data indicate high Ti parental magma for the Hongge ore-bearing clinopyroxenites. In the Panzhihua intrusion, the most important orebodies also occur as concordant layers but in its lower part instead of middle part. In contrast with the Hongge deposit, the most important host rocks of the Panzhihua deposit are gabbros, not …
Panzhihua deposit. The Panzhihua ore of V-bearing titanoferrous magnetite is found in the early basic–ultrabasic rock mass and belongs to the late magmatic differentiation deposit. The lithology of the ore-bearing rock, from top to bottom, is divided into three ore belts (gabbro, pyroxenite, and olivine), with five ore-bearing layers in the ...
An ilmenite ore with low TiO 2 grade was obtained from tailings of industrial iron recovery flowsheet of the vanadic titanomagnetite of Panzhihua in Sichuan Province, China. The ore was ground firstly to realize the liberation of ilmenite from residual magnetite, with the particle size below 0.074 mm accounting for 85%.
