Mining coal. Coal miners use large machines to remove coal from the earth. Many coal deposits, called coal beds or seams, are near the earth's surface, but others are deep mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.

In this process (known as mechanical alloying or cold welding), the kinematic porosity results in grinding media breaking the metals and additives into small particles first, then beating them together to form agglomerates. By repeating the process, the various metals are evenly mixed and dispersed to form a new composition of alloy (DSM).

The VortexIS can process the coal fines, which are mostly discarded and sit in sludge ponds or dumps. If boiler or kiln operations are adjusted for the VortexIS output, then coal fines can be used as input material. Typically 3 5% of coal paid for is lost to fines, which can't be processed through existing milling options.
