iteration of the mining plan is required to better suit the processing requirements. Either way, both money and time can be wasted. The optimum mine plan must recognise the balance between low cost, bulk, non-selective mining and the requirements of the process plant in treating the different ore types within the orebody.

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.
