A 1000-tonnes/day ore processing plant processes an ore that contains 20% mineral. The plant recovers 100 tonnes/day of the mineral. This is not a very effective operation, and some of the mineral is still in the waste ore (called the tailings). These tailings are sent to a

Question 4 3/3 pts A 1000-tonnes/day ore processing plant processes an ore that contains 20% mineral. The plant recovers 100 tonnes/day of the mineral. This is not a very effective operation, and some of the mineral is still in the waste ore (called the tailings). These tailings are sent to a secondary processing plant that is able to recover 50% of the mineral in the tailings. The recovered mineral from the secondary processing plant is sent to the main plant, where it is combined with the other recovered mineral, and then all of it is shipped to the user. How much mineral (in tonnes/day ) is wasted in the tailings ? 850 50 O 350 none of these O 150
