USIM PAC© 
Multipurpose Simulator for
Mineral Processing

If You are working in design, adaptation or optimization of processing plants involving:

• Crushing (Jaw, Hammer, Cone),
• Grinding (SAG/AG, Ball & Rod Mill, SAM),
• Classification (Screen, Cyclone, Rake & Spiral Classifier),
• Flotation (Conventional & Column Cells),
• Gravity Separation (Jig, Table & Spiral),
• Hydro-metallurgy (Leaching, CIP, CIL, SX, EW), etc.

USIM PAC© is designed to help you.

USIM PAC© is used by engineers in industrial operations, engineering companies and technical centers involved in the design and improvement of mineral processing and hydro-metallurgical plants, with commercial references all over the world.

The functions performed by USIM PAC© steady state simulator include data reconciliation, plant simulation, plant design and optimization, and cost estimation.

USIM PAC© can be used from the acquisition of experimental data (laboratory, pilot- or industrial plant data) to the development of an optimal flow sheet and the evaluation of  the corresponding capital investment.

USIM PAC© is supplied with more than 100 unit operation mathematical models for plant simulation, design and optimization including comminution, concentration and refining. The user may incorporate additional icons and models into the standard libraries.

To cater for the diversity of users (different application fields, countries, etc.) USIM PAC© is highly configurable. Icon names and model parameters can be easily modified to represent specific applications. Units and currencies can be adapted to the user's needs.

USIM PAC© requires no initial background in computing or modeling theory.

Plant Optimization

In existing plants, USIM PAC© is used to improve performance and evaluate new ideas. It reduces the number of industrial-scale tests, which are both expensive and difficult to interpret.

USIM PAC© can reconcile experimental data and establish detailed, consistent material balances. These material balances are not only a means of assessing plant operation. They are formatted for being used for model calibration. From reconciled data, USIM PAC© calculates the required parameters to adjust the mathematical models for a given project. This enables any process engineer to perform modeling without special assistance.

Plant Design & Cost Estimation

At the planning stage, USIM PAC© makes the best use of laboratory and pilot-scale experimental data and helps rapidly define and compare a large number of alternative configurations for the future plant. The simulator optimizes the sizes and some settings of the main units of equipment in order to achieve the desired plant performance.

USIM PAC© also calculates the approximate capital cost of the proposed configuration including individual costs of the main units of equipment and overall cost of the plant. The cost data base can easily be updated from time to time.

USIM PAC© software was developed and belongs to BRGM.
