Title: Extraction of metals and reduction Date
reactivity series (beneath copper) are found as elemental metals • This is because they have such low reactivity, that they have remained uncombined since they were first formed billions of years ago • The only extraction that is needed, is to dig them up through mining Platinum Gold Silver 5 Collect information about extraction of metals of low reactivity silver, platinum and gold and prepare a report A i Metals of low reactivity such as silver, mercury, platinum and gold are often found in free state ii Their reactivity with other atoms is very low iii The Oxides of these metals can be reduced to metals by heat alone andPrinciples of Metallurgy 13 Sakshi EducationVery few metals such as the noble metals, ie, Gold, Silver, and 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 environmentExtraction of Metals Methods of Extraction of Metals Traces of silver and gold collect as sludge at the bottom of the cell Note :To improve purity of the product of electrolysis, the following steps are advisable; Increase the dilution of the electrolyte/ use a very dilute electrolyte Reduce the amount of current / use a low current Summary of Extraction of Copper from Copper Pyrites Uses of METALS: EXTRACTION PROPERTIES AND USES Form Biohydrometallurgy has been commercially applied for the extraction of base metals from lowgrade sulfidic ores and the pretreatment of refractory sulfidic goldcontaining mineralsNew approaches for extracting and recovering metals
