The reduced ore occurs in the southern part which measures 7.8 by 2.7 km. Distribution of the ore oxidized ore

  16. 16. Fig.6 N-S x-section showing (URO) above the magnetic ore in South Tarot. Upper reduced ore (URO) is defined as the part of the reduced ore which is found above the magnetic ore, or when there is no magnetic ore, the whole of the reduced ore. Consequently, (uro) is found in great thickness out of the north, west and east sides of the magnetic anomaly and in lower thickness within the anomaly.

  18. 18. The non-magnetic reduced ore is mainly formed of siderite, chlorite and primary limonite. The iron content of this type of ore is definitely lower than the magnetic one. For an estimate tonnage of 375 million metric tons, the average iron content is 48%. Both ores are phosphorous with an average content of 0.9% P. The average thickness of total ore, i.e. lower reduced + magnetic + upper reduced ore, is 11.9meters.
  19. 19. magnetite ore (m) is found inside the zone as the magnetic anomaly area. The magnetic ore is mainly formed of magnetite and siderite in different proportions. This type of ore is the best quality found in Taroot deposit. The iron content depends on the siderite – grade is 55% for an estimated reserves of 420 million metric tons . The average thickness of ore is (8 m).
  20. 20. lower reduced ore (LRO ) is defined as the reduced ore found underneath the magnetic ore; consequently, it is always located within the magnetic anomaly. Fig.4 Surface Map showing N-S x-sections & open-cut B "northern limit" of ores (URO, M, LRO) in Magnetic Ore =420 MMT (URO+LRO)= 375MMT

  24. 24. CONCLUSIONS (French Group, 1973-1976). 1. Magnetic ore pellets have features which make it possible to use them in the blast furnace in a proportion not exceeding 30% of the blast furnace charge. 2. It is also possible to remove some impurities from the magnetic ore. 3. It should be noted that whatever the ore and the process used, the ore basic feature, i. e., its high phosphorous content, remains unchanged (WADI SHATTI IRON ORE COMMITTEES, 2008 - 2014). 1. For the time being: a. It is impossible to use the iron ore with phosphorous content higher than 0.05% in Medrix Way in our Reduction Plant at (LISCO), Misurata. b. Modern Technology can lower the phosphorous content down to 0.44%. c. If this way can be applied to our ore then we choose one of the two ways: 1. We build blast furnace and import coke or 2. We export the ore to other countries which have coke reserves.
  25. 25. Recommendations 1. Re-arranging and sorting the conventional cores at (IRC) is necessary in order to have a general look that helps in proposing new locations for new coring program. 2. Big rig with diamond coring bit and larger diameter as well as core barrel is needed. 3. Financial and authority are recommended for the committee chief. 4. As soon as the final invitation to tender is ready a list of different companies is recommended to be invited to submit their technical offers first and then commercial offers later. 5. Above all, Mr. president and all attendant's advices are highly appreciated.
