Oct 27, 2008 When sampling Iron Ore Fines being loaded onto a bulk carrier of 60,000 DWT, the international standard ISO 3082 indicates some 40 to 80 samples will be taken to obtain a representative sample. Do all these samples need to be sent to a laboratory Or how many samples need to be sent to a laboratory Can the samples be sub sampled to make composite samples to reduce the number of samples.

Foam glass composite with good capabilities was prepared from iron ore tailings as the main material by two steps. The phase composition and microstructure were determined by X ray diffraction and scanning electron microscopy. The effects of foaming temperature and sintering temperature on sample capabilities were studied by determining sample bulk density and compression strength.

Mr Illingworth says the trucking of iron ore has now stopped because Sherwin Iron has reached its short term mining limit. The company is only allowed to mine a 400,000 tonne bulk sample of ore.
For example, the daily, weekly and monthly indices are listed because of the varied liquidity displayed by different parts of the market. Sinter fines and lumps make up the bulk of the seaborne iron ore market, and are the products most frequently traded on a spot basis, so daily pricing is used for the key 62 Fe, 58 Fe and 65 Fe fines, and lump premium references.
