Methods of leaching sulphide ores can be: in absence of oxidizing agents in presence of oxidizing agents Bacterial leaching Absence of oxidizing agents Acid leaching: Dilute acids dissolve some metal sulphides with liberation of H2S, e.g. ZnS + 2H+ ^ Zn2+ + H2S Three types of sulphides can be encountered. Completely soluble sulphides: Zns, CoS, NiS, FeS Slightly soluble, e.g. . Supergene sulfide enrichment, also called Secondary Enrichment, in geology, natural upgrading of buried sulfide deposits by the secondary or subsequent deposition of metals that are dissolved as sulfates in waters percolating through the oxidized mineral zone near the surface. The ore thus enriched forms the secondary, or supergene sulfide, zone and overlies the primary, or .

Sulphide Marbles (Schiffer Book for Collectors) Paperback – Encased in clear or colored glass, molded sulphides come in many clever forms, including animals, birds, humans, mythological creatures, religious figures, mermaids, celebrities, and angels.
Included with the fascinating images is a detailed text recounting the 5/5(6). Finally, because Sulphides are single-pontil marbles, there is always one pontil on the surface. In some cases, this pontil is ground down. If the pontil is on the bottom pole of the marble, then the figure can be viewed properly from all angles.
However, depending on the skill of the maker, the pontil could end up anywhere Sulphides book the marble in. The present book deals with the chemical and catalytic aspects of transition metal sulphides, focusing on their use in hydrotreating catalysis. The book¿s 12 chapters present reviews of solid-state, coordination and organometallic chemistry, surface science and spectroscopic studies, quantum chemical calculations, catalytic studies with model.
Sulphide definition: A sulphide is a compound of sulphur with some other chemical elements. | Meaning, pronunciation, translations and examples. About this book Contains four chapters originally published in The Chemistry of Sulphones and Sulphoxides. Each chapter will be supplemented with an appendix of new material covering the developments in the areas since the publication of Sulphides book original volume in This book is concerned with the theoretical principles of hydrometallurgical processes and engineering aspects.
The hydrometallurgical processes of production of copper are discussed and leaching of chalcopyrite as the main sulphide mineral. Oliver J. Hao, in Handbook of Water and Wastewater Microbiology, Sulphide. Sulphide is known to inhibit SRB, a classic example of the product inhibition often encountered in chemical and biological processes.
Sulphide inhibits SRB probably when anyone of the sulphide species (H 2 S, HS − or S 2−) combines with the iron of ferredoxin, cytochromes or other. > Sulphide Technique: Search. a subject about which he wrote a book in Successful experimentation with cameo incrustation led to the discovery of a silica-clay mixture with a higher melting point that molten glass and a compatibility with glass in expansion and contraction.
These early glass-sheathed sulphides were enclosed in. Sulfide definition is - any of various organic compounds characterized by a sulfur atom attached to two carbon atoms. sulphide (ˈsʌlfaɪd) n 1. (Elements & Compounds) a compound of sulphur with a more electropositive element 2.

Most major ores of important metals such as copper, lead and silver are sulfides. Strong generalities exist in this class.
The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or dark-colored streaks, and an igneous origin.

another name for thio-ether Noun 1. sulphide - a compound of sulphur and some other. The sulfide minerals are a class of minerals containing sulfide (S 2−) or persulfide (S 2 2−) as the major sulfide minerals are economically important as metal sulfide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, the sulfarsenides and the sulfosalts.
Sulfide minerals are inorganic compounds. Sulphide Gold Recovery. Pre-concentration of coarse – micron sulphide-associated gold ore, using the InLine Pressure Jig, is required to reject gangue from the high value IPJ, a classic pre-concentration device, is effective in gangue rejection prior to further processing of valuable gold-bearing material.
Other turnkey modular systems for pre-concentrating coarse. The sulfide minerals represent higher temperatures and a slightly deeper setting than the sulfate minerals, which reflect the oxygen-rich environment near the Earth's es occur as primary accessory minerals in many different igneous rocks and in deep hydrothermal deposits that are closely related to igneous : Andrew Alden.
‘DOCs include all compounds of carbon except for its oxides, sulphides and metal carbonates if they are identifiable by chemical name.’ ‘The technique can identify iron-bearing phases (such as oxides, silicates, sulfides, sulfates, and carbonates), as well as the amount of iron in each phase and the presence of iron in various oxidation.
sulphide definition: 1. a chemical formed from sulphur and another element 2. mainly UK spelling of sulfide. Learn more. Metal sulphides are a highly important group of minerals as they are the major source of most of the world's non-ferrous metals, occurring in large concentrated orebodies, and also as minor, but significant, accessory minerals in a wide variety of rocks, some of which are also important sulphide ore deposits.
Sulfites in foods are often placed there as a preservative. While most governments have banned the use of sulfites in foods like fresh fruits and vegetables, they are still commonly used to preserve dried fruits, wine making, and to preserve seafood and other meats.
Sulphides prove real glass act for cameo collectors We previously reported the preparation and characterization of copper sulphide layers on polyethylene film (PE) of various densities by the sorption-diffusion method [2,3].
The sulphide minerals are compounds of the metals with sulphur. Nearly all these minerals have a metallic luster, i.e., the peculiar shining appearance of metals, such as gold, silver, copper, lead, tin, iron, etc. They are all heavy minerals and nearly all are of economic importance.

Look it up now. If you have asthma, there is about a % chance you have sulfite sensitivity. The United States requires labeling for sulfites in wine above 10 parts per million (PPM – or 10 mg/L). Overall, sulfur is prevalent in processed foods and thus, is on the rise as a concern for health problems (from migraines to body swelling).
So, how about. sulphide: see sulfide sulfide, chemical compound containing sulfur and one other element or sulfur and a radical. Sulfides may be salts or esters of hydrogen sulfide, H 2 S, or may be formed directly, e.g., by heating a metal with sulfur. Click the link for more information.
Sulfide mineral, any member of a group of compounds of sulfur with one or more metals. Most of the sulfides are simple structurally, exhibit high symmetry in their crystal forms, and have many of the properties of metals, including metallic luster and electrical conductivity.
