| DUMP BOX | Large heavy-duty Dump Box contains a sufficient volume of auriferous gravels to maintain constant feed to the distribution and recovery areas between cycles of the loading equipment. |
| DISTRIBUTION | The Primary Distribution area is
built into the dump box. It is constructed of heavy,
punched plates with adjustable pitch, normally flatter
than the general slop of the box. The purpose is to
ensure proper classification and feed control to minimize
"surging" of unwashed gravel into the recovery
areas. This promotes vigorous washing and
"liberation" of the gold particles which is
essential to maximize the high recovery capabilities of
the Ross Box. The Secondary Distribution area is utilized to classify the gravels, dropping the auriferous fines into the carefully controlled side recovery channels. |
| RECOVERY AREAS | The Primary Recovery area is located
immediately under the primary Distribution area and traps
the gold as it is released from the gravel due to
vigorous scrubbing action of the water. The Secondary Recovery areas are located downstream from the Secondary Distribution area. The fine gold is recovered in the side channels, and the gold nuggets are captured in the center channel. The Tertiary Recovery area is a find gold area, trapping gold released from the coarser material and clays travelling down the center channel. |
| WATER MANIFOLDS | The Main Manifold is adjustable
horizontally and can be rotated to provide a vigorous
scrubbing action and regulate the flow of materials into
the recovery areas. The two Swing Manifolds ensure
excellent dump box coverage and scrubbing of all fee
material. The Throat Manifold in the secondary distribution area ensures effective washing and classiin this zone. The optional Water Monitors mount on the main manifold and offer 360 degree rotation. The balanced design of these swiveling "water cannons" can greatly enhance washing and control of larger rocks with minimal operator effort. |
| CLEAN UP | During clean up, all of the concentrate is washed into strategically located pockets, to longitudinal tubes transporting the concentrate to the bottom end of the sluice box to maximize security and to simplify pickup. |
| CONSTRUCTION | The cast alloy steel puch plates are 3/4" thick for long wear, and contain tapered holes to minimize blinding. The reinforced square tube sub-frame and skid ensures strength and facilitates ease of movement with construction equipment. |
