ONGOING EVOLUTION IN DREDGE DESIGN PAYS OFF FOR WORLD'S PLACER MINERS

One of the methods used to mine placer deposits is dredging, defined as the underwater excavation of a placer deposit by floating equipment. This article gives a brief summary of minerals that are mined by dredging, and then reviews some improvements in dredge design. Features of the world's largest dredge, commissioned by a Malaysian company for mining a large, low-grade tin deposit, are briefly described, and some new dredge designs, recently patented for both bucket-line and suction dredges, are outlined.
