Manganese ore was mined from 1950 to 1971, most production being from Viti Levu in the 1950s. Magnetite was mined at Tuveriki in south-west Viti Levu from 1957 to 1963. Deposits of gold, polymetallic sulphides, and disseminated deposits are being explored, notably the Waisoi and other porphyry–copper deposits at Namosi on Viti Levu. ...
Table 1 illustrates the typical chemical specifications for standard HCFeMn (ASTM A99-03, 2014). In order to attain the specified chemical composition of HCFeMn, two or more manganese ores are added to the SAF (Submerged Arc Furnace) feed mixture, due to the different manganese to iron ratio values within each ore. ... Therefore, manganese ore ...
