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 of gold ore processing and production mainly includes three processes: crushing, grinding and beneficiation. In the crushing process, the three-stage closed-circuit crushing is more modern and suitable for high-hardness gold ore crushing, which can complete the work of ore crushing and partial dissociation, thereby improving the subsequent grinding efficiency;

Some of the features that may be used to identify gold ores include the geologic environment of the gold ore such as the iron oxides and quartz veins. The flow of acidic mineral solutions through fractures in the rock can form various types of deposits. Also, the erosion and weathering processes can either reveal or conceal the precious gold ores.
