About Mining and MineralsThe Mining Law, as amended, opened the public lands of the United States to mineral acquisition by the location and maintenance of mining claims. Mineral deposits subject to acquisition in this manner are generally referred to as "locatable minerals." Locatable minerals include both metallic minerals (gold, silver, lead, copper, zinc, nickel, etc.) Wet mining being dredge mining. In some countries mineral sand mining is carried out in a similar fashion as hard rock mining but in Australia it is mostly restricted to wet (dredging), or dry mining techniques: • Dry mineral sands mining requires the use of scrapers, excavators and trucks.

Clean sand is stockpiled until it can be loaded into trucks for final sorting and drying off-site. (Some mines sort and dry sand on-site rather than sending it out.) Because the sand still contains moisture when it is stockpiled, drain tiles beneath the piles channel water to a lined process-water pond. Mining of sand for extraction of heavy minerals only removes about 1% of the bulk of the sand, the rest being returned to the dunes in some form or other. Modern sand miners are required to reshape and revegetate the dune systems and leave them as close as possible to their original state (Unwin & Cook, 1986 cited in Burdett, 1994 ).
