Siderite
· Siderite Mineral Properties, Photos and Occurence. Siderite is both an iron ore and gangue mineral. Its principal economic value lies in its high iron content and the absence of process contaminants such as sulfur or phosphorous. It is part of a large group of isomorphous minerals, the calcite group carbonates, which share similar physical ...

Copper Processing | Equipment, Process Flow, Cases
· Flotation law of copper sulfide minerals (1) All ironfree copper minerals, such as chalcocite and covellite, are similar in floatability, and cyanide and lime have weaker inhibitory effects on them. (2) All copper minerals containing iron, such as chalcopyrite and bornite, are susceptible to inhibition by cyanide and lime in alkaline media.

Few unmelted particles of iron oxide (hematite) remain, whereas the formation of granular hematite ...
Gangue
Gangue minerals, once separated by mineral dressing processes of (most of) the valuable ore minerals and dumped in mine tailings may be a significant environmental impact. In particular, oxidation of pyrite, a common gangue mineral, is one of the main sources of acid mine drainage. Reuse. Minerals that were once thought of as gangue, and were dumped, may later find a commercial use.
