Mining platinum in placer deposits is a relatively simple process. Dredges scoop the platinum-bearing sand or gravel from riverbeds or mining pits. The material is washed until platinum grains or nuggets are captured and pulled from the surrounding material. Sperrylite, or platinum arsenide. Photo from Thomas A. Loomis, Dakota Matrix Minerals.
Alluvial diamond mining process. Some diamonds were released from volcanic pipes by erosion of the earth's surface…they were then washed away down ancient riverbeds or to coastal areas. This action created alluvial deposits from which diamonds are recovered.
Alluvial gold mining is the mining of stream bed deposits for minerals. Alluvial mining is frequently used for precious gold deposits which are often found in alluvial deposits i.e. in the sand and gravel of the river/stream beds. Alluvial gold deposits over a time when a river runs through ground that is rich in gold. The water erodes the surrounding rocks due to its comparative low density ...
