Process Introduction. Tin ore is usually separated by gravity separation because its density is greater than that of paragenetic minerals. However, since the ore may contain various iron oxide minerals (such as magnetite, hematite, etc.), these minerals are difficult to be effectively separated from tin ore by gravity separation or flotation, so magnetic separation or …

iron ore is expected to rise by more 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.
