Extractive Metallurgy | Introduction to Chemistry

An ore is a type of rock that contains minerals with important elements such as metals. Ores are extracted through mining; they are then refined to extract the valuable element(s). The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining it. The cost of extraction must be weighed against the metal value contained in the rock to determine which ores should be processed and which ores are of too low a grade to

Copper processing - Ores | Britannica

Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.
