- The non-metal ions lose electrons to the anode (this is called oxidation) and are discharged as non-metal atoms which often combine to form molecules. In this way, elements that are present in ionic compounds can be separated by electrolysis. This method is used for the extraction of some metals from their ore.See for example lead bromide, magnesium chloride, potassium chloride, sodium chloride and zinc chloride.he non-metal ions lose electrons to the anode (this is called oxidation) and are discharged as non-metal atoms which often combine to form molecules.

Ore 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.n ore deposit is an accumulation of ore. This is distinct from a mineral resource as defined by the mineral resource classification criteria. An ore deposit is one occurrence of a particular ore type.

- Instead, it is extracted by electrolysis. The ore is first converted into pure aluminium oxide by the Bayer Process, and this is then electrolysed in solution in molten cryolite-another aluminium compound. The aluminium oxide has too high a melting point to electrolyse on its own.

- To be useful, the metals have to be extracted from whatever they are mixed with. A metal ore is a rock containing a metal, or a metal compound, in a high enough concentration to make it economic to extract the metal. The method used to extract metals from the ore in which they are found depends on their reactivity.o be useful, the metals have to be extracted from whatever they are mixed with.

extract (metallurgy). To separate a metal or a mineral from an ore by various chemical or mechanical methods. (pharmacology). A pharmaceutical preparation obtained by dissolving the active constituents of a drug with a suitable menstruum, evaporating the solvent, and adjusting to prescribed standards.

- A standard method used for this task is an extraction or often also referred to as washing. Strictly speaking, the two operations are targeting different parts in the mixture: while the extraction removes the target compound from an impure matrix, the washing removes impurities from the target compound i.e., water by extraction with saturated sodium chloride solution.

Separating Mixtures If your solid does not dissolve in water, for example chalk, then you can separate the solid from the liquid by filtering the suspension through filter paper. In this example the chalk that remains on the filter paper is called the residue.ou can separate many solids contained in saturated solutions by leaving them to form crystals. This process is called crystallisation. If the solution is saturated, then when the solvent evaporates, what's left behind can't hang on to as much of the solute. So the solute leaves the solution and forms crystals.

- The method used to extract a metal from its ore depends upon the stability of its compound in the ore, which in turn depends upon the reactivity of the metal: 1  The oxides of very reactive metals, such as aluminium, form stable oxides and other compounds.

Metal Basics Metals usually make positive ions when the compounds are dissolved in solution. Also, their metallic oxides make hydroxides (bases) (OH -), and not acids, when in solution. Think about this example: When sodium chloride (NaCl) is dissolved in water (H 2 O), it breaks apart into sodium (Na+) and chlorine (Cl -) ions.

- Another criterion that distinguishes a compound from a mixture is that constituents of a mixture can usually be separated by simple mechanical means, such as filtering, evaporation, or magnetic force, but components of a compound can be separated only by a chemical reaction.

- About 91 of the 118 elements in the periodic table are metals (some elements appear in both metallic and non-metallic forms). Astrophysicists use the term metal to collectively describe all elements other than hydrogen and helium.hen a metal ore is an ionic compound of that metal and a non-metal, the ore must usually be smelted — heated with a reducing agent — to extract the pure metal. Many common metals, such as iron, are smelted using carbon as a reducing agent.

Electrolysis Extraction of aluminium. Aluminium is extracted from it's ore by electrolysis. The electrolyte has to be molten ore, if a solution was used (as in the extraction of copper) hydrogen gas would be produced instead of the pure metal.

Types of Extraction Many metals are found in the Earth's crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal.

- Sulfur and iron: since this is a mixture, the sulfur retains its properties (its yellow color, for example), and the iron retains its properties (its black color, for example). These properties can be used to separate the two elements. For iron sulfide, two elements (sulfur and iron) are heated together so that they form the compound iron sulfide. Although iron sulfide contains both sulfur and iron, it is not a mixture: it is a pure substance. Both the sulfur and the iron have “given up” their individual properties to become a compound.

- Filtration, evaporation, crystallisation and drying are four techniques used in the isolation and purification of a solid product from a chemical reaction e.g. How can we separate a mixture of sand and salt? or, how do we separate a salt from a salt preparation?onsequently on cooling a hot concentrated solution, crystals form as the solubility gets less and less and the solubility limit is exceeded, so crystals must form. Crystallisation is also an important purification method because trace impurities tend to stay in solution.

Separation of Substance This method of handpicking can be used for separating slightly larger sized impurities like the pieces of dirt, stone, and husk from wheat, rice or pulses (Fig. 5.3). The quantity of such impurities is usually not very large. In such situations, we find that handpicking is a convenient method of separating substances.
