Abstract The Herberton Mineral Field in Northeast Australia hosts world class magmatic-hydrothermal Sn–W polymetallic deposits that are enriched In. Baal Gammon and Isabel from the contains early tin, as cassiterite, overprinted by sulfide mineralization chalcopyrite, sphalerite, galena, pyrrhotite, stannite. We investigated distribution of In ores these two deposits, calculated temperature for...

In this investigation, Ti/TiN nanolayer and TiN single layer coatings were coated on substrate of AISI 316L stainless steel by applying physical vapor deposition (PVD) using the type of cathodic arc evaporation (CAE). The evaluation of microstructure were carried out using x-ray diffraction (XRD), nanoindentation, atomic force microscopy (AFM) as well as scanning electron microscopy (SEM). Pola...

This paper mainly investigated the synthesis of a high purity PbS crystal directly from lead ash which was collected Tin removal process (LATR). The LATR firstly disposed by nitric acid leaching system to generate nitrate solution. prepared mixing solution with sodium sulfide at room temperature (25?C). effects molar ratio HNO3 Pbin on Pb efficiency investigated, demonstrating that could attain...

electrosynthesis process has been used for preparation of zinc sulfide nanoparticles. zinc sulfide nanoparticles in different size and shapes were electrodeposited by electrolysis of zinc plate as anode in sodium sulfide solution. effects of several reaction variables, such as electrolysis voltage, sulfide ion concentration as reactant, stirring rate of electrolyte solution and temperature on p...

The tunable bandgap from 0.3 eV to 2 of black phosphorus (BP) makes it fill the gap in graphene. When studying properties BP more comprehensive, scientists have discovered that many two-dimensional materials, such as tellurene, antimonene, bismuthene, indium selenide and tin sulfide, similar structures thus called analogs. In this review, we briefly introduce preparation methods its analogs, wi...

Toxic effects of sulfide come from a poisoning of a number of enzymes, especially cytochrome c oxidase, which catalyzes the terminal step in mitochondrial aerobic respiration. Despite this, some estuarine plants live in sulfide-rich sediments. We hypothesized estuarine and flooding-tolerant species might be more tolerant of sulfide compared to upland species, and this was tested by measures of ...

Interactions between iron and sulfide in domestic wastewater from a gravity sewer were investigated with particular emphasis on redox cycling of iron and iron sulfide formation. The concentration ranges of iron and total sulfide in the experiments were 0.4-5.4mgFeL(-1) and 0-5.1mgSL(-1), respectively. During anaerobic conditions, iron reduction kinetics were investigated and reduction rates amo...
