Copper(II) bromide | CuBr2 - PubChem

Acidic inorganic salts, such as COPPER BROMIDE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids ...

Comparing lead and copper activation on pyrite with ...

Copper ions are often added in the flotation of gold-bearing pyrite to activate pyrite so that high gold and pyrite recoveries can be achieved. However, the residual copper ions are problematic in subsequent cyanidation by consuming cyanide. There is a great need to replace copper ions by lead ions which are beneficial to cyanidation. This study compared lead and copper activation on pyrite ...

Pyrite is an impurity mineral in bentonite and other clays proposed for use as sealing materials for the planned KBS­3 repository for the disposal of spent nuclear fuel in Sweden (Karnland 2010, Pusch 2001). The pyrite may have a number of effects on the evolution of the repository and the behaviour of …

List Non-Metallic Mineral Names

Since the pyrite weathers more easily than the rocks bounding it, it tends to form hollows between the rocks. Deposits of iron pyrites often contain enough copper to make them valuable as copper ores, and sometimes gold and silver add to the value of the ore; but the presence of other sulphides may decrease the value.

What is "Fool's Gold?" - USGS

Fool's Gold can be one of three minerals. The most common mineral mistaken for gold is pyrite. Chalcopyrite may also appear gold-like, and weathered mica can mimic gold as well. Compared to actual gold, these minerals will flake, powder, or crumble when poked with a metal point, whereas gold will gouge or indent like soft lead. In addition, actual gold will leave a golden
