Converting is a key unit process for pyrometallurgical smelting of sulfide concentrate of copper and nickel. During converting, air or oxygen-rich air is used to oxidize and eliminate the sulfur and iron in the matte (copper matte or nickel matte) melt, and generate crude copper or high-grade nickel matte. Traditional converting usually …

Sulfur is a non-metallic element that is found in the earth's crust. It is odorless and colorless and has a melting point of 112.5 degrees Celsius. Sulfur is not magnetic, but it is diamagnetic, meaning that it repels magnets. This quality is shared by all non-metallic elements. Sulfur is an important component of many compounds, inc…See more on yesdirt

NMR - Interpretation. Page ID. Nuclear Magnetic Resonance (NMR) interpretation plays a pivotal role in molecular identifications. As interpreting NMR spectra, the structure of an unknown compound, as well as known structures, can be assigned by several factors such as chemical shift, spin multiplicity, coupling constants, and integration.
