•As mined, iron ore contains three times the percentage of iron oxide as other solid impurities. Water is used to transport the iron ore into a separator. Two streams emerge from the separator: the washed ore stream has 62.8 % iron oxide, 3.8% solid impurities and water as the remainder . The waste stream has 3.6% iron oxide, 33.7% solid impurities and water as the remainder. The total washed ore stream flow rate is 37.2 tonnes/hr. All percentages are by mass.
•Determine:
i) the output (t/hr) of iron oxide plus solid impurities from
the washed ore stream
ii) the total water output (t/hr)
iii) the input stream (t/hr)
