  • Heavy mineral sands ore deposits Wikipedia

    Heavy mineral sands are placer deposits formed most usually in beach environments by concentration due to the specific gravity of the mineral grains. It is equally likely that some concentrations of heavy minerals (aside from the usual gold placers) exist HEAVY MINERALS IN ALASKAN BEACH SAND DEPOSITS,Beach sand deposits along Alaska's shoreline have been prospected and worked for their precious metal content since the time of Russian occupation. Areas such as the Nome Beaches of the Seward Peninsula have been very produc- tive, and in recent years exploration has ~roceded to include off shore extensions of these deposits.
