Trilogy Featured Service for Placer Mining

Modern Technology Engineering became the first successful company in 1984 to manufacture and put into operation the largest specific gravity gold/black sand concentrating wheels in the world.

These 8′, 5′ and 3′ trailered combination concentrating wheels, puts all other production concentrating units to shame in several ways. With the highest concentrating capabilities in the world in its price class, MTE’s concentrating wheels have continuous recovery (no shutting down to clean out), are hydraulically controlled without electricity (about 5 gallons of fuel per day), and uses less water than jigs and bowls (About 60 gallons per minute recycled). Most importantly it is considered Green Mining technology. Each unit from MTE ($120K) is equal to 4 comparable jig or bowl units ($400K-$800K). This technology is endorsed as an Environmentally Friendly Green Solution.
