iron ore to world markets for steel production 14 In January 2013 TTL engaged Boffa Miskell Limited (BML) to investigate and review natural character, landscape/seascape and visual amenity matters with respect to the potential effects of the proposed Offshore Iron Sand The project would have involved the excavation of up to 50 million tonnes (27 million cubic metres) per year of seabed material containing iron sand for processing on an offshore floating vessel Approximately 10 per cent of the material would have been processed offshore into iron ore Case Study South Taranaki Bight iron sand extraction The mineral is often mined as an ore of Iron, and lately, through the use of magnetic separator / processing plant and chemical intervention, Magnetite Iron Sand became a primary source of raw material like Iron Ore for Steel and Cast Iron manufacturers when they are developed in the form of Iron Lumps, Balls, Fines, and PelletsENVIRONMENTALLY SAFE AND EFFECTIVE OFFSHORE

Magnetite Mining in the Offshore Areas of Cagayan*

Colossal Mining Corporation, a 100 % Filipino owned company that engages in exploration, mining, and production of iron ore in the Philippines, holds three exploration permits of 36,000 hectares of offshore magnetite iron ore sites in Northern Luzon (Cagayan, Ilocos Norte, and Ilocos Sur) of which 13,48389 hectares are located in the province The iron ore concentrate makes up about 10 per cent of the iron sand and the remaining sediment is returned to the seafloor Export The iron ore concentrate will be stored temporarily in the IMV before being transferred as slurry to the transshipment vessel Fresh water from the desalination plant will be used to rinse salt from the iron oreSouth Taranaki Bight TransTasman Resources The probable ore reserve in the area is around 6317 million metric tons (MT) JDVC said in an earlier presentation posted on its website that the extraction of iron sand, whether taken from the offshore, or within the 20 kilometer radius would be very simplePH’s 1st largescale offshore mining to start in January
