Oct 09, 2014 This report briefly characterizes the geology of iron ores and the economics of the industry. Following this discussion is a review of iron ore extraction and beneficiation methods this section provides the context for descriptions of wastes and materials managed by the industry, as well as a discussion of the potential environmental effects.
Iron ore is expected to rise by than 200 million tonne per year to meet the internal demand export. This additional requirement of iron ore will need beneficiation of low grade ore fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.
May 09, 2015 In the present investigation an attempt has been made to beneficiate goethitic iron ore containing 59.02 Iron, 6.51 Alumina, 4.79 Silica, 0.089 Phosphorus with 7.11 loss on ignition. For this purpose, different beneficiation techniques such as gravity and magnetic separation processes have been employed. During the process two conceptual flow sheets were also developed.
