Abstract
AN interesting account is given in the G.E.C. Journal of February of the electrical equipment for the Bremang Gold Dredging Co., Ltd. This company dredges for alluvial gold on the Ankobra River, one of the larger rivers of the Gold Coast Colony, which flows roughly north and south and pours itself into the Gulf of Guinea. Many of the shallows of the river are sufficiently rich in alluvial gold deposits to warrant commercial development, and the Bremang Gold Dredging Co., Ltd., has installed equipment at two of these points for dredging mud and gravel from the river bed from which the gold is recovered. The dredges are electrically operated and are supplied from individual substations fed by a 55 kv. overhead transmission line from the power station of Ankobra Junction, a distance of about twenty miles.
