Abstract

667,641. Excavating earth. KELMAN, A. J., MALAYAN TIN DREDGING, Ltd., SOUTHERN MALAYAN TIN DREDGING, Ltd., TRONOH MINES, Ltd., SOUTHERN TRONOH TIN DREDGING, Ltd., and AYER HITAM TIN DREDGING, Ltd. March 14, 1950. No. 6389/50. Class 68 (i). An installation for mining alluvial deposits comprises a pontoon 1 on which is mounted a mooring winch 2 that traverses the pontoon at a rate which synchronises with the mean rate of digging of a grab or grabs 6 suspended from the jibs 5 of the level luffiing non slewing type at the prow of the pontoon. Also mounted on the pontoon are the winches 8 for operating each grab, a common hopper 12 receiving the alluvial from the hoppers 10 beneath each jib and a mineral treatment apparatus to which the alluvial is conveyed by a feed conveyer 13 and an upwardly inclined screening conveyer 14. The mineral treatment apparatus comprises a revolving screen 15 on the fore-and-aft axis of the pontoon, the screen having a stone discharge shoot 17 and two sets of concentrators 16 arranged symmetrically in relation to the revolving screen and tailing shoots 18 extending rearwardly from said sets of concentrators over the stem of the pontoon.
