Welcome to SMC Testing - The official site of the SMC Test®.

SMC Testing Pty Ltd is a privately owned company that was formed in 2004 to license the SMC Test® – a laboratory comminution test which provides a range of information on the breakage characteristics of rock samples for use in the mining/minerals processing industry.  To date approximately 10,000 SMC Tests have been conducted covering over 500 different ore bodies. This constitutes one of the largest data bases of its kind in the world.

The SMC Test® was developed by Dr Steve Morrell as a cost-effective means of providing accurate data on the breakage characteristics of rock samples which can be used for a range of purposes including comminution circuit design and optimization, ore body profiling, geometallurgical modeling and Mine-to-Mill studies. The test was originally developed to allow the use of small quantities (a few kilograms) of quartered (slivered) small diameter drill core, although whole core, half core and lump rock can also be used with ease.

The SMC Test® itself uses a device called the JK Drop Weight Tester to break tightly controlled suites of rock particles.  The device is supplied by JKTech Pty Ltd and is currently used by 13 commercial metallurgical laboratories around the world. SMC Testing has granted licenses to these laboratories to carry out the SMC Test® as well as 3 in-house mining company laboratories.

For information on the cost to conduct SMC Tests® please contact your nearest licensed metallurgical laboratory.
