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 furnace.

Very few metals such as the noble metals, i.e., Gold, Silver, Platinum, etc are present in their original metallic forms in nature. Metallurgy is the field of science which deals with the extraction of metals from ores which are naturally found in the environment.
In each case, the metal ion in the compound gains electrons, ie they are reduced. Ores of very reactive metals have to be melted and electrolysed with a DC direct current supply of electricity.
The metal ores are found in the earths crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground ... The metals are one of the three groups of elements as distinguished by their ionization and bonding properties, along with the metalloids and nonmetals. ... On the periodic table, a ...
Most metals are obtained in the form of compounds and they need to be filtered from their impurities to be further used for various applications. The process of procuring metals from ores is called metallurgy and these naturally occurring compounds of metals are known as minerals. Metals are usually extracted from the earth by mining.
an ore of tin Mineral. Part A The table lists several ores of metals and their chemical formulas. Identify the metal that each mineral ore is a source of by looking at the formula. You can use your ESRT to find the symbol for each element. Write the name of the metal in the appropriate column.
INCORRECT QUESTION 6 OF 6 The metals Mg and Al, like most metals on the left of the periodic table, cannot be obtained by chemical reduction with carbon at reasonable temperatures. What process is used to obtain these metals from their ores electrolysis 0.05 false standard CORRECT Metals that are very difficult to reduce are produced using ...
The other alkali metals and the alkaline earth metals are recovered from their ores by similar process General Properties of the Alkali Metals Various properties of the group 1 elements are summarized in Table 213 quotSelected Properties of the Group 1 Elementsquot
Most sulfides are electrically conducting, generally semiconducting, and this allows electrochemical reactions to occur at the solidsolution interface In fact, electrochemical mechanisms play a key role in each of the processes that are involved in obtaining the component metals from their sulfide ores, namely, prospecting for ores weathering ...

Extracting Metals from their Ores. Extracting Metals from their Or The majority of metals do not occur native and, instead, are compounds like sulphides or oxid These compounds are called minerals and a rock which contains a mineral is known as an ore Metals can be extracted from ores using a range of methods The best technique to use depends on...
Examples of Metal Ores. The term ore is used to refer to a rock that contains minerals such as metals. In general, ores are oxides, sulfides, silicates or native metals,quot those found in nature. Oxides and sulfides are called such because the minerals contain oxygen or sulfur, respectively, which has formed a ...
