Overview
Metsim International, LLC (MSI) is a software and services provider for mining and metallurgical operations. MSI is headquartered in Churubusco, Indiana, and it has offices in eight countries.

History
In 1978, John Bartlett developed a simulation software for mining operations, focusing primarily on conducting mass balances for mineral processing plants. The software was first registered in 1982. In the 1980s and 1990s, several new unit operations were introduced, and new calculation methodologies were employed for static and dynamic simulation.

John Barlett died in 2018. In 2018, the METSIM® software became a part of the offerings of Metsim International, a company formed by the original partners of METSIM® and the family of the founder.

Today, METSIM® is a simulation software for metallurgical and chemical engineering processes.

Software
METSIM® is a general-purpose process simulation system designed to assist the engineer in performing mass and energy balances of complex processes, and it is also used in as the basis of technical research and papers. METSIM® uses an assortment of computational methods to affect an optimum combination of complexity, user time, and computer resources usage.

METSIM® is actively maintained and releases new versions quarterly.

Software APIs with external organizations

 * In 2023, MSI and OLI Systems, Inc linked OLI's Electrolyte Simulation to the METSIM® software.
 * In 2023, MSI added a fully integrated API to Geochemist's Workbench for water chemistry calculations.
