文摘
- •
Small sizes of particles are required in order to separate the different fractions.
- •
Inverse flotation process is an efficient green technology to separate fractions.
- •
Superficial air velocity is the main variable in the inverse flotation process.
- •
Inverse flotation is a green process because the pulṕs pH is 7.0 during the test.
