The proven global tin reserves were reported to be approximately 4.7 million tons (Mts) in
2016, and among these resources, only approximately 2.2 Mts can be recovered …

Cu‐based bifunctional materials were examined for carbon dioxide conversion, thus
producing the syngas from hydrogen, which can be attained using surplus electrical energy …

Tin-containing slag from pyrometallurgical recovery process of spent lead-acid battery is a
valuable secondary Sn resource. However, the low content of Sn (~ 4 wt%) in this slag with …

Abstract Groundwater in Upper Egypt especially in Assiut Governorate is considered the
second source of fresh water and used for drinking, agriculture, domestic and industrial …

Solid-state reaction method is a common and effective technique to synthesize ferrites. This
work investigated the phase transformation of MnO 2 and Fe 2 O 3 system roasted at 500 …

Chemical vapor transport (CVT) process is a simple and efficient method for synthesizing
nano-SnO products, and previous references reveal that the CVT process is characterized …

Our former study reported that Fe-Sn spinel (Fe3− xSnxO4) was easily formed when SnO2
and Fe3O4 were roasted under CO-CO2 atmosphere at 900–1100° C. However, the …

Part of tin in the magnetite-type tin-bearing ores existed as isomorphous Sn 4+ in the lattice
of magnetite (Fe 3-x Sn x O 4, X= 0–1.0), which was impossible to separate and recover by …

The reserve of tin-bearing iron ores is very large in China. However, they have not been
utilized sufficiently so far due to the complex embedded relationship between iron-and tin …

ABSTRACT High-purity Na2SnO3 has been prepared by a novel process of roasting SnO2
and Na2CO3 in a solid state under CO–CO2 mixed gas. In the current study, the phase …
