Safe carriage of Iron ore other iron concentrates in bulk

In the carriage of iron ore, the following precautions should be taken: Iron ores are heavy cargoes which occupy a small area for a large weight, ie they have a low stowage factor (between 0.240.80 m3/tonne). It is therefore important that the tanktop has sufficient strength to carry certain iron ores. If a bulk carrier loads a homogeneous

associated Indian iron ore. Based on this process flowsheet, number of beneficiation plants were set up. Graphite Beneficiation Advanced process flowsheet was developed to maximise the flaky graphite and high carbon value from the graphite ore. Simultaneously, high purity (upto 100% Carbon value) and colloidal graphite processes were developed.)
