Indonesia will need to rely on low rank coals to meet regional demand as deposits of high quality coals become scarce, delegates heard at the Coaltrans conference.
Indonesia's coal resources in 2010 amounted to around 105 billion tonnes, of which 65% are low rank coals, Chief Technical Officer at Agritrade Resources Peter Gunn said.
Most bituminous resources have already been identified and non-coking ones are now being developed, he said, adding this excluded the largely unexploited coking coal deposits in Central Kalimantan.
The majority of sub-bituminous resources are also being developed and in production. Crusher
However, the key Challenge in developing these deposits was in attaining investment, as low-rank coals are mostly sub-economic - meaning they can be used at the mine site only, and cannot be transported far, Gunn said. Crushers Plant from China
Low rank coals are also vulnerable in a volatile market, he said. When prices drop, low-rank producers are often priced out of the market. Grinding Milling
