use of anfo in iron ore surface mining

  • Higher Energy Bulk Explosives – Matching Products to Rock Types

    Traditional bulk explosive products for surface mining applications (ANFO, heavy ANFO and pumped emulsion-based explosives) span a range of relative bulk strengths (RBS) from approximately 100 to 200 percent of that of ANFO. In this paper, RBS has been derived Amex™ ANFO is free flowing and can be easily loaded into boreholes, delivering maximum energy to the borehole. Best suited to dry conditions, Amex™ ANFO have variants Amex™ - Orica2021年1月24日  Our new powerful ANFO explosive with biowaste dung were used in blasting work of Tumurtolgoi iron ore open-pit mine. Ammonium nitrate (NH4NO3) is the Open Access proceedings Journal of Physics: Conference series

  • ANFO - Wikipedia

    In surface mining applications, it is typically loaded into boreholes by dedicated trucks that mix the AN and FO components immediately before the product is dispensed. In underground mining has depleted near surface ore rich veins. Over the past ten (10) years or so, the Cripple Creek Victor Mining operation used a 50/50 Heavy ANFO Bulk ISEE Paper Evaluation of Advanced Bulk Emulsion Explosive and 2022年10月4日  The effects of rock fragmentation on the whole size reduction chain from mining to mineral processing are described. The main factors influencing rock Reduction of Fragment Size from Mining to Mineral Processing: A

  • Tackling nitrate contamination of water in mines

    2016年8月11日  “Recent international studies suggest that up to 28% of nitrates [1] from traditional ammonium nitrate fuel oil (ANFO) explosive can leach into water draining through underground mine workings...This study purposes to analyse the results and impact of ANFO and emulsion explosive in order to know the advantages and disadvantages of each explosives.
