### The mixing tank (BL4001) has infeed of mineral particles coming from the grinding mills. Before feeding pulp or slurry to flotation cells, pulp gets mixed with chemicals, fine minerals particles, and water, which form the slurry for flotation process. Chemicals

### The rougher bank (FA4010 to FA4013) contains four flotation cells (See Fig: 2.1). Each cell has 160 m

### The scavenger bank (FA4014 to FA4018) contains five flotation cells, each cell has 160 m

### • The Rougher Cleaner 1 contains three flotation cells (FA4320, FA4321 and FA4322). Each cell has 60 m

### • Scavenger Cleaner 1 (FA4323 to FA4326) contains four flotation cells. Each cell has 60 m

### • Cleaner 2 contains five flotation cells (FA4510 to FA4514). Each cell has 40 m

### • Cleaner 3 contains four flotation cells (FA4530 to FA4533). Each cell has 40 m

### • Cleaner 4 contains three flotation cells (FA4550 to FA4552). Each cell has 40 m

### The measurable output signals are shown in Fig.2.1, Details about rougher, scavenger, cleaner 2, cleaner 3, and cleaner 4 are summarized below

### Rougher 16 m
