The installation in 1948 of a Humphreys spiral concentrator section at the Hill-Trumbull plant of The Cleveland-Cliffs Iron Co. is the latest commercial method on the Mesabi Range being used for the recovery of fine iron ore. In two stages of concentration 84 spirals treat approximately 120 long tons per hour of minus 1/8 in. ore.
Blue Bowl Concentrator makes quick work of removing black sand from your gold dust. Blue Bowl Concentrator Kits include pump. Blue Bowl leg levelers also available for use on a 5 gallon bucket.
The slurry was fed to the spiral via a distributor with an overflow pipe to maintain a constant feed rate into the spiral. This was a closed-circuit spiral test with a sump and pump. During each test, the spiral was run until steady-state conditions were reached before taking the relative density (RD) measurements at the top of the spiral rig.
