  • Blasthole Cone Sampling Experiments for Iron Ore Flitch Mining

    Blasthole cone samples are used for grade control in most of the iron ore mines of the Pilbara of Western Australia This method of sampling is straightforward when the target sampling interval matches the mining bench height but is problematic when the blasted bench is flitch' mined in two or more passes Crucially, the sampler needs to decide which part of the blast coneNov 27, 2019· McArthur G, Jones C, Murphy M (2010) Blasthole cone sampling experiments for iron ore flitch mining In: Proceedings sampling 2010 Mežibricky R, Frohlichova M, Legemza J (2019) HighSiO ({2}) iron ore sintering: Central & Eastern Europe scenario Metalurgija 58(1–2):161–164 Google Scholarblasthole cone sampling experiments for flitch mining

    The conclusion from the debate over the last decade in the mining sector is that, for grade control, reverse circulation (RC) drill sampling gives more reliable results due to less sampling problems than blasthole samples However, by conducting the latter with wellcontrolled procedures there still exist fair possibilities to counteract the major blasthole samplingBlasthole Cone Sampling Experiments for Iron Ore Flitch Mining Go to Paper; Planning for the Expected Amount of Variation to be Acceptable Go to Paper; Understanding the Mechanisms That Can Cause Sample Bias Go to Paper;Sampling 2010 Conference AusIMM
