Curd and other sour substances are acidic in nature, if kept in brass or copper vessels, will react with the metal. The reaction will spoil the food and make unfit for human consumption or may cause food poisoning.

oxides because oxygen is a very reactive element and very abundant on the earth. An ore contains a metal in the form of its compound with other elements. So, after the mining of thea of metal. The ores are converted into free metals by a number of steps which depend on the type of the involved in the extraction of metals from their ores, and refining are known as metallargy. The process to be used varies forg that no single process can be used for the extraction of all the metals. The process to be used of a metal from its ore are : metal to metal. The three major steps involved in ther (i) Concentration of ore (or Enrichment of ore), (ii) Conversion of concentrated ore into metal, and (iii) Refining (purification) of impure metal. We will now describe all these steps in detail, one by one. Let us start with the concentration of ort 1. Concentration of Ore (or Enrichment of Ore) Ore is an impure compound of a metal containing a large amount of sand and rocky material. TI unwanted impurities like sand, rocky material, earthy particles, limestone, mica, etc., present in an mas are called gangue. Before extracting the metal from an ore, it is necessary to remove these impuritisis gangue). The methods used for removing gangue from ore depend on some difference in the physical propertiot chemical properties of the ore and gangue. By removing the gangue, we get a concentrated ore containing! much higher percentage of the metal. We will discuss the various methods of ore concentration in highe classes. Please note that the concentration of ore is also known as enrichment of Metal Method of ore. 2. Conversion of Concentrated Ore into Metal (i) Metals of high reactivity (or Highly reactive metals) (ii) Metals of medium reactivity (or Moderately reactive metals) (iii) Metals of low reactivity (or Less reactive metals) Different methods are used for extracting metals belonging to the above three categories. This is shown in Figure 73. Manganese metal ) lies just above zinc in the reactivity series (but it has not been shown in Figure 73). Manganese carbon. This is because carbon is less reactive than manganese. Please note that ) Found in and of all other metals below zinc to form metals. Another point to be noted is that tin metal is more reactive than lead , so its place is just above Pb in the reactivity series. A yet another point to be noted is that copper can be extracted its of a metal fro its concentrated by the reduction of its oxide with carbon as well as by heating its sulphide ore depends on its chemide in air.
