B Processing of Sulfide Ore Sulfide ores are generally processed using pyrometallurgy the extraction and purification of metals by processes involving the application of heat This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores in four basic steps 1 froth flotation 2
· One of the most common processes of extracting silver metal for the ore is the heap leach or cyanide process The process is most popular with many miners because it is low cost especially when processing low grade ores To use the cyanide process the silver being in the ore should have smaller particles should be able to react with the cyanide solution the
Vor 2 Tagen · The ore of the metal is made to react with a suitable chemical reagent leading to the dissolution of only the metal leaving behind the impurities which remain undissolved The solution so obtained is a compound of the metal that can be further processed to extract the pure metal There are many different types of leaching processes which are mainly categorized
to be extracted by a process called electrolysis Metals with low chemical activity such a gold and silver are normally found in their pure state Copper tin lead and iron are more reactive and must be heated with carbon to extract the metals Aluminum calcium sodium and other active metals are extracted using electrolysis Copper can be extracted from its ores by reduction
