Metals such as zinc, iron and copper are present in ores as their oxides. Extraction of metals from ores. electrolysis(using electricity). During extraction of metals from oxide ores, the reduction of metal ore to crude metal can be carried out by using several methods such as pyrometallurgy, hydrometallurgy and electrometallurgy. contents. 2.2 extracting iron. zexplain the process involved in the extraction of Al, Fe, Cu, and Zn. PowerShow.com is a leading presentation/slideshow sharing website. Presentation Summary : Extracting metals. ... or clay) is used to dip into the smelter to extract molten metal and ore. An ore is usually a compound of the metal mixed with impurities. Pyrometallurgy • Smelting • The metal oxides can then be smelted by heating with coke or charcoal (forms of carbon), a reducing agent that liberates the oxygen as carbon dioxide leaving a refined mineral. 6 of 19 © Boardworks Ltd 2016 The ore is removed from the ground in either open pit or underground mines. enrichment of, 4.10.2007 - / t/daimler trucks master . 2. extraction log viewer.

Our new CrystalGraphics Chart and Diagram Slides for PowerPoint is a collection of over 1000 impressively designed data-driven chart and editable diagram s guaranteed to impress any audience. To this are added, Collectors and Froth Stabilizers. Selectivity and recovery are a function of the reagents used and the contaminants present. Precipitation will proceed when, through reagent addition, evaporation, pH change or temperature manipulation, any given species exceeds its limit of solubility. reactivity series metals and acids displacement metal oxides and acids metal, Properties of Metals, Non-Metals and Metalloids - . metalloids. These transformations may produce pure metals, or intermediate minerals or alloys , suitable as feed for other refining or commercial applications. The methods which could be used for extracting precious metals from e-waste are similar to traditional hydrometallurgical technology used for metals extraction from their primary ores. Most metals can’t resist natural processes like oxidation, corrosion, etc. igcse. The ores are very different from the finished metals that we see in buildings and bridges. EXTRACTION OF METALS A guide for A level students - . Concern about the production of carbon dioxide is only a recent worry, following the identification of the greenhouse effect.

The crust of the earth provides metals and it is a good source to procure metals. They'll give your presentations a professional, memorable appearance - the kind of sophisticated look that today's audiences expect. Titanium is used for the positive electrode. Mostly, the metals occur in nature in a combined state but sometimes they can also occur in the free state. The PowerPoint PPT presentation: "Extraction of metals from their ores" is the property of its rightful owner. Age group: Form 3, 14yrs. Reactive metals are hard to reduce so need a powerful method of extraction, which is electrolysis. The choice of the process depends upon the nature of the ore and the type of the metal. The process of extracting metal ores buried deep underground is called Mining. Or use it to find and download high-quality how-to PowerPoint ppt presentations with illustrated or animated slides that will teach you how to do something new, also for free. occurrence • ores of some metals are very common (iron, aluminium), Metals - . There are detailed notes on the extraction of iron and its conversion to steel. CrystalGraphics 3D Character Slides for PowerPoint, - CrystalGraphics 3D Character Slides for PowerPoint. Extracting Metals. only some unreactive metals such as silver, gold and platinum can occur freely in nature. • Leaching • Leaching uses an aqueous solution containing a lixiviant which is added to the ore. How are metals extracted from mineral ores? Metals having low reactivity show little affinity for air, moisture, carbon dioxide or other non-metals present in nature. • The thermodynamic tendency towards precipitation is shown using Pourbaix diagrams, however these do not show the kinetics or speed at which the salt or metal will be precipitated. The carbon displaces the metal from the compound, and removes the oxygen from the oxide. These transformations may produce pure metals, or intermediate minerals or alloys , suitable as feed for other refining or commercial applications. metal ores how to extract metals from ores ? The method of extraction which is most appropriate depends on the reactivity of the metal being extracted. Boasting an impressive range of designs, they will support your presentations with inspiring background photos or videos that support your themes, set the right mood, enhance your credibility and inspire your audiences. • Other materials may need to be added as flux, aiding the melting of the oxide ores and assisting in the formation of a slag, as the flux reacts with impurities, such as silicon compounds. The extraction and manufacture of aluminium and sodium are described. Copper can also be extracted from solutions of copper sulfate by carrying out a displacement reaction using scrap iron. Pyrometallurgy: A process in which the ore is reduced to metal at high temperature using a suitable reducing agent like carbon, hydrogen, aluminium, etc. uses, properties and structures and modifying metals.
