Copper extraction - Wikipedia
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors..

SEPARATION TECHNIQUES - Sepali's Chemistry Guide
SEPARATION TECHNIQUES If a substance does not dissolve in a solvent, we say that it is insoluble. For example, sand does not dissolve in water – it is insoluble. Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: • the sand stays behind in the filter paper (it becomes the,
