noge 4.24 A 1000-tons/day ore-processing plant pro- cesses an ore that contains 20% mineral. The plant recovers 100 tons/day of the mineral. This is not a very effective operation, and some of the mineral is still in the waste ore (the tail- ings). 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 recovery 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. douns om di to neup s a.
