Copper Ore Types: Sulfides vs. Oxides | Investing News Network

Copper Ore Types: Sulfides vs. Oxides. Both ore types can be economically mined, though they are processed in different ways. Copper sulfide ores are typically the most profitable copper ores to mine. That is because they have high copper content, and the copper in them can more easily be separated from unwanted minerals. However, copper oxide ores are more abundant....

What is the difference between silica and silicon dioxide?

Minerals, Rocks Rock Forming Processes

Felsic Minerals: Felsic is a term used for silicate minerals, magmas, and rocks which have a lower percentage of the heavier elements, and are correspondingly enriched in the lighter elements, such as silica and oxygen, aluminum, and potassium. The term is a combination of FEL (for feldspar; in this case the potassiumrich variety) and SIC (indicating a higher percentage of silica)....

Silicate Wikipedia

In geology and astronomy, the term silicate is used to mean silicate minerals, ionic solids with silicate anions; as well as rock types that consist predominantly of such minerals. In that context, the term also includes the nonionic compound silicon dioxide SiO 2 (silica, quartz), which would correspond to x = 2 in the general formula....
