Figure 1.1.10. Typical sinter for blast furnace process (size: ≤25 mm) [22]. 1.1.3.2.2 Pellets 1.1.3.2.2.1 Pelletizing Process Similar to sintering, pelletizing is another widely used process to agglomerate the iron ore. Sinter plants are usually located near the blast furnace plant, but...
Many diverse ore systems are classified together as iron oxide copper-gold (lOCG) deposits based on an empirical definition arising primarily from geochemical features that do not specify tectonic setting, geologic environment, or sources of ore-forming fluid, metals, or other ore components. Such...

The Qinling Orogen is a composite orogenic belt that can be subdivided into the North and South Qinling, broadly separated by the Shangdan suture zone. These two orogenic belts were generated by subduction-collisional processes in the Early Paleozoic and Late Triassic, respectively. During the Late...
~ 10 Mt ore has been mined. Despite the economic importance of the Montecristo vein, this study focuses on the currently mined Abundancia vein and the cropping out but unmined San Juan vein due to its key geological characteristics. The Abundancia vein contains both MtAp and IOCG ...
When mining the ore body under buildings, appropriate mining methods should be employed based on the occurrence conditions of the ore body, so that the deformation of surface buildings caused by underground mining can be controlled within the allowable range. Based on the mining practice under ...
It is bounded by 2.0 to 1.9 Ga orogenic and tectonic belts (Figure 1) that formed during the amalgamation of Laurentia, the ancestral North American core [25], and the supercontinent Nuna [26]. The 2.0–1.9 Ga Taltson and Thelon suture zones border the western Rae (Figure 1) and ...
Women’s graves contain brooches (sometimes more than one), the metal parts of belts, spindle whorls and small knives with an arched blade. Pottery is a frequent element of the grave inventory as well. The Jastorf Culture of the Elbe River Basin In the second half of the 1st millennium ...
