Electron self-exchange activation parameters of diethyl sulfide and tetrahydrothiophene
Electron transfer between the title compounds and their radical cations, which were generated by photoinduced electron transfer from the sulfides to excited 2,4,6-triphenylpyrylium cations, was investigated by time-resolved measurements of chemically ...

ENRICHMENT OF MASSIVE SULFIDES FROM THE SEMENOV HYDROTHERMAL CLUSTER (MID-ATLANTIC RIDGE) IN BARITE: A RESULT OF E-MORB INVOLVEMENT AND MAGMATIC CONTRIBUTION [PDF]
The paper reviews and compares the barite findings in hydrothermal fields of the midoceanic ridges. The genetic significance of barite is considered for the Semenov hydrothermal sulfide cluster associated with an oceanic core complex (OCC) at 13°30′ N of

SULFUR SOURCES OF SULFIDES OF THE AK-SUG CU-AU PORPHYRY DEPOSIT, EASTERN TUVA [PDF]
The paper presents the S isotopic composition of sulfides from the Ak-Sug Au-Cu-porphyry deposit hosted by Early Proterozoic magmatic rocks. The S isotopic composition of sulfides varies from +1.0 to +3.2 ‰: +2.5 to +3.2 ‰ for molybdenite-I, +1.0 to +3.1

Experimental Research on Environmental Friendly Gold Leaching of a Refractory Gold Ore in Laos
The gold ore type of the gold mining in Laos is altered rock. Gold is the only recyclable element in the ore. Metal minerals are mainly iron sulfides. Part of the gold is wrapped in sulfide, which belongs to the refractory gold ore.
