steel research international, EarlyView.On the pathway to climate‐neutral steel production, recycling fractions will necessarily increase over time. Since alloying elements will enrich progressively, as they cannot be removed economically from the melt, processes need to be adjusted.

Antimony quartz and antimony-gold quartz veins from northern Portugal [PDF]
, 2008 Antimony- and Pb-Sb-quartz veins from the Bragança district, Portugal, are mainly hosted by Silurian phyllites. Antimony-Au-quartz veins from the Dúrico-Beirã region are mainly hosted by a Cambrian schist-metagraywacke complex, as well as Ordovician ...

steel research international, EarlyView.A CALculation of PHAse Diagrams thermodynamic modeling for Fe–Sn–C system is carried out. The model and the developed database can be used to calculate phase diagrams and thermodynamic properties of this system over wide temperature/composition range, and a part of a larger thermodynamic database for steel and alloy system, and effectively used to ...

steel research international, EarlyView.This review explains how impurities from recycled scrap affect steel production and performance. Even small amounts (far below 1%) of these impurities can change how steel behaves during fabrication but also affect the properties of the end product. With better understanding and targeted countermeasures, these challenges can be managed, enabling wider ...

A study of the antimony-ore deposit at Mt. Amatsutsumi, Nishimera-mura, Koyu-gun, Miyazaki Prefecture, Japan [PDF]
, 2012 Fujimoto (1999a) found the antimony-ore remains on the northern slope of Mt. Amatsutsumi, Nishimera-mura, Koyu-gun, Miyazaki Prefecture. In 2002 and 2003 we surveyed the area, took some ore samples and investigated them by microscope, X-ray diffraction ...

ANTIMONY LEACHING FROM STIBNITE AND COMPLEX ORE
Journal American Society of Mining and Reclamation, 2006 To shed light on the leaching of Sb from mine wastes containing stibnite, two series of experiments were conducted. In one experiment, polished slabs of a museum-grade stibnite and a mixed-sulfide ore sample containing 28% Sb were subjected to accelerated weathering at 100% humidity and 31-35C for 37-44 days.
