The basic extraction of metals from ores has the following steps. 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.
Metal extraction is the process of extracting metal from its ore. A number of steps are used to transform ores into free metals, depending on the type of ore, the nature of …
EXTRACTION OF METALS. Extraction is the process whereby metals are obtained from their ores. The ores are reduced to respective metals in the process. The metallic ions gain electrons and become the corresponding atom. Example; -The extraction can be done in two methods; Electrolytic reduction Chemical reduction
