What are the extraction of metal

Apr 29, 2021

Sep 27, 2021 Extraction of metals is a complicated process and sometimes involves two or more processes to extract the pure element from its ore. The extraction of iron from its ore is an important topic for both class 12th board and JEE. it is explained as follows:

    The basic extraction of metals from ores has the following steps. 1. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later. In technical terms, it is called pulverisation. 2
