Flotation automation is not simply about controlling the start and stop of flotation machines; its core lies in the detection and regulation of key process parameters.

It mainly includes:

1. Pulp level
   Maintain the relative stability of the flotation cell level through level detection and regulation by equipment such as valves.
2. Pulp flow rate
   Monitor the feed and pulp flow rates to provide basic data for subsequent reagent control.
3. Pulp density
   Changes in density will affect the flotation process and need to be controlled in conjunction with the process requirements.
4. значение pH
   Conduct online detection and automatic regulation of pH according to the ore type and reagent regime.
5. Reagent dosage
   Achieve the quantitative addition of reagents such as collectors, frothers, and regulators through equipment such as metering pumps and flow meters.
6. Air input (aeration rate)
   Regulate the air input according to the requirements of the flotation process, which affects bubble formation and the flotation process.
7. Froth layer and froth state
   Combine information such as liquid level, froth thickness, or froth images to assist in judging the flotation state.

Therefore, the core of flotation automation can be understood as:

Detect process parameters → PLC/DCS analysis → Regulate equipment → Feedback correction.

The ultimate goal is not to let the equipment “run automatically,” but to make the flotation process more stable, providing a control foundation for the stability of grade and recovery.
