Minerals and Ores & the extraction of Minerals | The Chemistry Journey | The Fuse School

Learn the basics about Minerals and Ores from a perspective of the Chemical Sciences. At Fuse School, teachers and animators come together to make fun & easy-to-understand videos in Chemistry, Biology, Physics, Maths & ICT. Our OER are available free of charge to anyone. Make sure to subscribe - we are going to create 3000 more! Fuse School is currently running the Chemistry Journey project - a Chemistry Education project by The Fuse School sponsored by Fuse. These videos can be used in a flipped classroom model or as a revision aid.

Making Potassium metal -Magnesium Reduction method.

Making potassium metal. KEEP IN MIND THIS IS A DANGEROUS PROCEDURE!!! THINGS CAN GO WRONG!! FIRES CAN RESULT!!! DO NOT ATTEMPT THIS WITHOUT FIRST KNOWING THE SYNTHESIS AND RISKS INVOLVED!!! paraffin oil is the medium and high quality 99.9% Mg metal shavings and reagent grade KOH and Tert butanol were also used. The oil,Mg, and KOH were placed into a 100ml flask fitted with a reflux condenser and heated to 250C. the catalyst was then added and the whole thing left to reflux for several hours yielding K metal by the end of the reaction. Lots of credit to the guys at SM: http://www.sciencemadness.org/talk/viewthread.php?tid=14970 And verschemie for their help with the process used here....

Types Of Ores

Follow us at: https://plus.google.com/+tutorvista/ Check us out at http://chemistry.tutorvista.com An ore is a type of rock that contains minerals with important elements including metals. The ores are extracted through mining, these are then refined to extract the valuable element(s). The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighted against the contained metal value of the rock to determine what ore can be profitably extracted and what ore is of too low a grade to be worth mining. Metal ores are generally oxides, sulfides, silicates, or "native" metals (such as native copper) that are not commonly concentrated in the Earth's crust or "noble" metals (not usually forming compounds) such as gold. The ores must be processed to extract the metals of interest from the waste rock and from the ore minerals. Ore bodies are formed by a variety of geological processes. The process of ore formation is called ore genesis. Important Ore Minerals •Acanthite: Ag2S for production of silver •Barite: BaSO4 •Bauxite Al2O3 for production of aluminium •Beryl: Be3Al2(SiO3)6 •Bornite: Cu5FeS4 •Cassiterite: SnO2 •Chalcocite: Cu2S for production of copper •Chalcopyrite: CuFeS2 •Chromite: (Fe, Mg)Cr2O4 for production of chromium •Cinnabar: HgS for production of mercury •Cobaltite: (Co, Fe)AsS •Columbite-Tantalite or Coltan: (Fe, Mn)(Nb, Ta)2O6 •Galena: PbS •Gold: Au, typically associated with quartz or as placer deposits •Hematite: Fe2O3 •Ilmenite: FeTiO3 •Magnetite: Fe3O4 •Molybdenite: MoS2 •Pentlandite:(Fe, Ni)9S8 •Pyrolusite:MnO2 •Scheelite: CaWO4 •Sphalerite: ZnS •Uraninite (pitchblende): UO2 for production of metallic uranium •Wolframite: (Fe, Mn)WO4 Please like our facebook page http://www.facebook.com/tutorvista

GCSE Science Chemistry Unit 1. Lesson 19. Four metals you need to know.

In this video, we look at the definition of the word "ore", which frequently comes up in exams. We then explore four different metals: Iron, copper, aluminium and titanium.

More than two decades we are working for the enterprises of mining and chemical industries: supply equipment for new processing plants and modernize existing ones. Today is no exaggeration to say that all the processing plants of Belaruskali, JSC, are using scientific developments of PASSAT holding, embodied in its equipment. They’ve found application in Russian companies too, such as Uralkali and Eurochem.
