Iron Ore Deposits in Sri Lanka ~ Lanka Pradeepa

Dec 24, 2020  Investigations have revealed that the deposit composed of an ore reserve of 4 million tons with 1-2% copper and 40% metallic iron (The National Atlas of Sri Lanka, 2007). The ore occurs up to a depth of about 100 m, which limits the open cast mining as in the case of the Panirendawa deposit (Fernando, 1986). Hydrated iron ore deposits.

May 26, 2015  The iron content is high, but considerable amount of copper (in the form of Chalcopyrite) is also associated in this magnetite ore. Therefore, the direct smelling process cannot be used to extract iron from this ore. In Sri Lanka there are no iron extraction industries from iron ore. There are few companies producing iron and steel from scrap iron.

Time Domain Electromagnetic (TDEM) surveys are used to detect changes in subsurface conductivity. This can be particularly useful in the detection of base metal deposits due to the high contrast in conductivity between the ore body and the host rock. Other subsurface features such as saline and contaminated groundwater sources, paleochannels and shear zones present []
