Iron Sulfides and Concrete
sulfide mineral, but can still oxidize near the surface of concrete and stucco, leading to unsightly staining and pop-outs. In good-quality dense concrete, aggregate containing small amounts of pyrite can be successfully used without affecting durability of the structure. Pyrrhotite oxidizes more readily in concrete than pyrite. ReactionsLearn More

Aureus East Mine | Aurelius Minerals Inc.
Sulphide minerals, in order of decreasing abundance, include arsenopyrite, pyrite, galena, sphalerite, chalcopyrite, pyrrhotite and stibnite. Gold commonly occurs with galena and arsenopyrite, with galena being considered the best indicator sulphide for gold. Arsenopyrite, up to a few percent, occurs within the veins and the wall rocks.Learn More

The Complete Classification of Minerals
Minerals of the sulfide class are compounds which contain the nonmetallic element sulfur in combination with atoms of a metal or a semimetal. Compounds in which anions of antimony ( Sb ), arsenic ( As ), selenium ( Se ), or tellurium ( Te ) replace the sulfur anion and bond with metallic or semimetallic cations are classed respectively as ...Learn More

Sulphide - an overview | ScienceDirect Topics
Precious metal sulphide deposits generally contain less than 1 modal % sulphide, whereas base metal sulphide deposits contain 5 to 100 modal % sulphide. The distinction is an arbitrary one, but it is a consequence of the extreme sensitivity of precious metal concentrations to the mass ratio of silicate to sulphide melt that equilibrate during ...Learn More

Introduction. T he term ‘non-sulfide’ is used to define a type of Zn-Pb ore deposit dominated by ‘oxidized’ Zn and Pb ore minerals, and is applied to distinguish such deposits from entirely sulfide deposits (Large, Reference Large 2001; Hitzman et al., Reference Hitzman, Reynolds, Sangster, Allen and Carman 2003).Non-sulfide Zn-Pb deposits can be classified into two types: supergene ...Learn More
