"U-TECH is dedicated to producing the ultimate gravity concentrating equipment on the world market. This is achieved by combining the world's most used and successful gravity concentrating table with a "unique" reverse polarity magnetic separator. Designed for hard rock gold mines, placer gold deposits, or heavy mineral separations.
Spinning rare earth magnets are placed underneath the deck surface of a U-TECH concentrating shaker table. Reversing the magnetic polarity of magnetite at about 800 cycles per minute, magnetite will rise to the surface of the feed material and will be washed into the tails by the transverse flow of wash water.
An ABS plastic one-piece molded riffled deck and launder tray is incorporated into the RP-4 gold shaker table. RP-4 shaker concentrating tables will process up to eight hundred pounds or more per hour (average 400 lbs. black sands) of sand-sized feed with little or no loss of gold. Four hundred pounds of river gravel with a maximum size of 3/4" inch can be processed when using a U-TECH submerged deck screen. With the factory-installed deck screen the RP-4 gold separating table will operate as a shaker screen, a magnetite separator and gold gravity concentrator.
U-TECH gravity concentrators will recover 99% of microscopic gold from your magnetite concentrates and is designed to run continuously.
Competitive tests with drum magnetic separators, spiral separators, concentrating bowls, gold centrifuges, vanners, micron tables, and static charges prove the RP Gravity Concentrating Tables to be superior in speed, recovery and economics.
RP-4 mineral concentrating tables are factory designed with a raised riffle for maximum recovery of micron-sized gold and platinum metals.
RP-4 gravity concentration tables weigh 60 lbs. and require about 8 to 14 gallons of water per minute. Table comes equipped with a 1/2 HP motor and uses 8.6 amps. 1/3 HP motor is optional at 6.8 amps."
