Extraction of Metals from Their Ores, The method that is used in the extraction of metal from its ore depends on the position of the metal in the reactivity series of metals metals that are located lower than carbon in the reactivity series of metals can be extracted using the reduction of metal oxide by carbon in a blast furnaceMetals and their ores complete list, Apr 26, 2018· Ores are naturally occurring rocks that contain metal or metal compounds in sufficient amounts to make it worthwhile extracting them For example, iron ore is used to make iron and steel Here, we providing a List of some Important metals and their or it is mainly useful for your upcoming competitive exams like SSC, UPSC etcHydrometallurgical process for extracting metals from ,, An improved hydrometallurgical process for extracting metals from ocean-mined ferromanganese nodul The process includes the steps of contacting the ferromanganese nodules in an extraction zone with an aqueous solution containing effective amounts of chloride ions and nitrate ions necessary to displace metal values in the ore at an elevated temperature and continuing the contact to form an ,Minerals and Ores: Definition, Types and Formation, Feb 23, 2016· Ores are those minerals from which metal are extracted conveniently and profitably Types of Ores There are mainly four types of ores such as Oxides; Carbonate Ores; Sulphide; Halides OresWhy are metal sulphides and carbonate converted into metal ,, Conversion of concentrated ore into metal oxide It is easier to obtain metals from their oxides rather than from carbonates or sulphid So the ore is first converted into an oxide A carbonate ore is first converted into oxide ore by calcination A sulphide ore is converted into oxide ore by roasting 1 Calcination process.

Carbon Reduction Method for Extracting Metals from their ,, The more active (or reactive) a metal is, the more stable the compound it forms and the greater the energy required to produce the metal from its ore Very active metals ( Group 1 , Group 2 and aluminium) require electrolysis to extract the metal while very inactive metals like gold and silver can occur in nature as the element so require no ,metallurgy: Separation of the Metal | Infoplease, For example, certain copper oxide and carbonate ores are treated with dilute sulfuric acid, forming water-soluble copper sulfate The metal is recovered by electrolysis of the solution If the metal obtained from the ore still contains impurities, special refining processes are required Introduction; Concentration of the Ore; Separation of the ,GCSE CHEMISTRY, Extraction of Metals What is a Metal Ore? A solid element or compound which occurs naturally in the Earth's crust is called a mineralA mineral which contains a high enough percentage of a metal for economic extraction is called a metal ore Economic extraction means that the cost of getting the metal out of the ore is sufficiently less than the amount of money made by selling the metalList of Important Metals and their Ores, Dec 21, 2016· Ores are those minerals from which metals are extracted commercially and economically Like Bauxite (Al 2 O 3 2H 2 O) is the ore of Aluminium which contains 50% to 70% of Aluminium OxideMetals from Ores: An Introduction, For example: Chromites ores [1] These are classified into three grades: Metallurgical Ore with a high chromium content (minimum 68% chromium) and the chromium/iron ratio must not be less than 28/1, will be suitable for the manufacture of ferrochrome alloy or chromium metal Table 1: Metallic minerals for other uses than metal production.
