Grinding circuit optimization
Material grinding (and crushing) is one of the most important steps in extracting minerals from ores. Optimal design of grinding circuits for both consistent product quality and energy efficiency is crucial for the minerals plant’s performance. Control of grinding circuits is difficult due to significant time delays and time lags in the process and due to variable material properties of the incoming ore. ABB's solution for comminution optimization offers:

Optimal output at given product quality
Better performance of downstream processes due to better control of the grinding process
Increased mill liner lifetime

Flotation optimization
Flotation is a key process in many mineral plants to separate the product mineral from the gangue. The key requirement of the system is to achieve optimum product quality with minimum reagent consumption. Control is difficult due to variable chemistry and size distribution of the material fed to the process. ABB's solution for flotation optimization offers:

Improved circuit control to optimize separation of the product from gangue
Optimum reagent consumption

Kiln and calciners optimization
Kilns and calciners are used in many minerals processing plants either as an intermediate process or as a final step to produce a finished product. The process is characterized by high fuel consumption. Control is difficult due to internal cycles in the kiln and the uncertain raw material properties.
ABB's solutions for kilns offer:

Consistent control of the temperature profile
Optimization of the temperature profile to minimize fuel consumption
Reduced product variability
Longer campaigns by increasing the life of the refractory lining
Increased output by reduction of process disturbances

Tangible benefits
Typically process optimization will enhance your kiln, your communition, and your batch-continuous process scheduling as well as control your flotation. Expected benefits of a process optimization deployment project are:

Increased recovery by 1 to 2%
Reduced quality variability by 25%
Energy savings 3 to 5%
Increased liner lifetime 10%
Reduced grinding media consumption 5 to 10%
Lower emission levels 3 to 5%

Qualitative benefits

Operational discipline
Environmental compliance
