The Metal Recovery System (MRS) came about through years of “hands on”
working with a wide variety of gold and other heavy metal collection
systems where metals require separation by gravity. During the design
of this system, consideration was given to almost every type of heavy
metal in almost every type of base material or ore.
The MRS systems are available in production capacities of 20 cubic
yards per hour up to 200 cubic yards per hour. The systems are designed
and fabricated using sturdy steel construction that will stand up to
multiple moves during use in the field. The systems are available in
trailer or skid-mounted models.
Features of the MRS System:
The MRS System features a material feed system with gravity grizzly
and variable feed control, a screening plant with dense rubber
balls installed in the second deck to assure the dissolution of heavy
clay and sticky materials which enhances the recovery rate of heavy
metals, particularly when small particles of heavy metals are present.
The MRS System design uses a deep troughing, rough face belt with a
radial (chevron) rib pattern. The belt speed is variable via the use of
a Variable Frequency Drive (VFD) controller. The belt runs on an
incline and the angle is adjustable. Two conveyors of the same size
make up one unit. The conveyor units move simultaneously in a lateral
movement, each opposing the other, and the speed of the lateral
movement is also variable, controlled by a VFD. A hydraulic powered
cylinder located near the discharge end of the conveyor frame is used
to push the entire conveyor frame up the incline, and move the conveyor
frame back to its lower position, with the speed of both motions having
variable speed control. Therefore, the system has the following
variable controls:
• Digital Feed Rate Control
• Digital VFD Conveyor Belt Control
• Digital VFD Lateral Movement
Speed Control
• Digital Repeating Timer/Flow
Control for Incline Movement
• Adjustable Pitch or Angle
• Adjustable Water Flow
Heavy Metals are collected in the upper side of the belt ribs and fine
particles are collected in the top of the belt and in the pinch point
where the rib is attached to the belt. The collected metals are carried
to the discharge hood where water spray is used to wash down the belt
and ribs, collecting the heavy metals in the collection pan. Water
flowing down the collection pan moves the collected metals to the
Velocity Reducing/Elliptical Oscillation Heavy Metal Trap. (VREOHMT)
The VREOHMT is designed to slow down the water flow, allowing the
capture of extremely fine particles. The standard unit slows down the
water flow 4 times. The elliptical Oscillation movement assures
continuous washing of the heavy metals until the metals are trapped in
the grid or in the collection mat. A VREOHMT is also installed at the
end of each conveyor to capture and high-float heavy metals that may
have escaped at the collection belt. For security purposes, the
VREOHMT is furnished with a multiple lock cover. The unit is also
furnished with a spare grid and collection mat to reduce clean-up
downtime.
Features and Benefits of the MRS System:
• Heavy Steel continuously Welded
frame and structure
• Available in Trailer or Skid
Mounted Units
• Production capacities from 20 to
200 cubic yard per hour
• Continuous Process and minimal
cleanup downtime.
• Uses no chemicals and uses less
water than standard trommel/sluice systems.
• Versatile and effective in a
wide range of ore types and base materials.
• Effective in collecting
particles down to two digit micron size.
• Easy setup, tune-in, and
operation
The Metal
Recovery
System (MRS) was developed by Business Resources, LLC and is the most
efficient precious metal mining equipment on
the market.
