Grade is the share of valuable metal in an ore – % Fe for iron, % Cu for copper concentrate, g/t for gold. Iron ore prices are set against the Platts/Fastmarkets “62 % Fe fines CFR China” index: 65 % Fe high-grade concentrate and pellets sell at a premium and 58 % Fe low grade at a discount. Pricing also applies penalty or premium scales for silica, alumina, phosphorus, sulphur and moisture. For concentrates, treatment and refining charges (TC/RC) and penalties for deleterious elements such as arsenic and mercury are negotiated as well.
