It is sometimes in round grains (shot ore), or in porous round lumps or flat cakes. When ground fine, it forms a yellow powder. Siderite. Siderite or spathic iron ore, is usually gray or white; but at the surface it weathers to limonite, and the weathering may extend to a considerable depth. A rusty capping may cover a deposit of siderite.

The process mineralogy of gold: The classification of ore types

In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold (<10 µm) locked in sulfides. Other types of problem gold ores include copper-gold ores and preg-robbing carbonaceous ores.
