Milling and crushing:

• Milling breakage curves

• Crushing gradation curves.

Particle size distributions:

• Cycad Process^® can track and calculate the changes in particle sizes in processes such as milling and leaching

Designers:

• Designers are used to target process unit outputs and sometimes referred to as ‘controllers’
• Unit-specific and flowsheet (general) designers are available
• Many solver methods available for both sets of designers – Bisection, Secant, Ridders, Brent (default)

Outputs:

Compare:

• Comparing results between different versions or calculations can be difficult and time consuming for even a relatively small balance. Cycad Process^® has a ‘Compare Cases’ function

Parameter estimation:

• Uses Levenberg–Marquardt algorithm to fit parameters
• Can be used to fit most process unit parameters using measured data

Dynamic simulations:

• Dynamic modelling of heap leaching operations
• Dynamic processes, such a as the batch distillation of ruthenium
• Contact our engineers should you wish to perform these simulations
