Volcanogenic Massive Sulphide Deposits
Volcanogenic massive sulphide (VMS) deposits are also known as volcanic-associated, volcanic-hosted, and volcano-sedimentary-hosted massive sulphide deposits. They typically occur as lenses of polymetallic massive sulphide that form at or near the seafloor in submarine volcanic environments. They form from metal-enriched fluids associated with seafloor hydrothermal convection. Their immediate h...
متن کاملOutcome after hydrogen sulphide intoxication.
AIM Hydrogen sulphide (H2S) intoxication in man is frequently associated with a fatal outcome. In small animal models hydrogen sulphide has demonstrated profound protection against hypoxia. No reports that focus on a potential protective effect in humans have been published. METHODS The frequency and outcome of a large cohort of hydrogen sulphide intoxications is described. RESULTS From 198...
متن کاملHydrogen sulphide production by bacteria.
Hydrogen sulphide production by growing cultures and non-multiplying suspensions was compared and the factors influencing the sensitivity of the tests were investigated. Cysteine hydrochloride (0.01 yo) was added to Lemco broth to provide a medium with a standard source of sulphur. H,S was detected with lead acetate papers more readily than by lead acetate agar. Suspensions were tested with cys...
متن کاملChallenges in Sulphide Mineral Processing
Scientists and technologists in world over are making large efforts to streamline the conventional technological schemes of ore processing, in particular froth flotation towards reducing overall costs, limiting the use of dangerous substances, decreasing waste streams and improving waste disposal. Hitherto, search for such innovations has been performed mainly empirically and there is an urgent...
متن کاملCadmium sulphide / Zinc sulphide quantum dot decoration of three-dimensional porous graphene
Graphene, a monolayer of graphite, has appeared as one of the most fascinating materials of today’s Material Science research. The properties of graphene (GR) with high electronic conductivity, extraordinary strength and interesting chemical characteristics make it suitable for many different applications. All these tremendous properties of GR are relevant at the nanoscale, hence, in a view to ...
