JKSimMet

JKSimMet integrates data analysis, mass balancing, model fitting, optimisation, design, and simulation within one package for comminution and classification circuit analysis. It includes validated models for crushers, autogenous (AG) and semi-autogenous (SAG) mills, ball mills, rod mills, screens, and hydrocyclones — all built on decades of JKMRC research into comminution fundamentals.

Designed for plant metallurgists optimising circuit performance and design engineers assessing configuration alternatives, JKSimMet predicts product flows, size distributions, power draw, and throughput under varying feed conditions and operating parameters. Version 6 is the current release. The software is a closed package — users cannot add custom process models — which distinguishes it from more open platforms like SysCAD or METSIM, but simplifies deployment for operations focused specifically on comminution circuit work.

JKSimMet is used worldwide across base metals, precious metals, and bulk commodity operations. It is particularly valued for its integration with JKTech's accredited ore characterisation testing program, providing a continuous pathway from ore hardness testing through circuit modeling to operational optimisation.
