Experience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sies, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding. For example, if the chrome is not entirely freed until the ore is minus 16 mesh, it is obvious that the plus 16 mesh particles should be removed after stage crushing and grinding to prevent further reduction of the chrome and consequent loss in the fine sies.

The crushing section for this 250 ton per day chrome mill consists of a coarse ore grily, a coarse ore bin with pan feeder to a 1821788243 reduction crusher and a crusher discharge conveyor to a crushed ore bin. On this particular ore, we find that there is no chrome liberated in sies larger than 8221.

The 368243x 88242 Adjustable Stroke Ore Feeder is used to accurately control feed of crushed ore to the grinding section. Before it is fed to the 48217x 88242 Peripheral Discharge Rod Mill, the minus 8221 chrome ore is removed from the grinding circuit by means of a 48217x 128242 Dillon Vibrating Screen. This minus 8221 product is then ready for concentration in the Mineral Jigs.

The Vibrating Screen oversie is ground in the Steel Head Rod Mill. A rod mill with the peripheral discharge feature is preferred for this application because the 82168221rapid-pass design produces a minimum of the undesirable fines. The discharge from the rod mill returns to the Dillon Vibrating Screen by means of a Belt Bucket Elevator, so that a closed circuit grinding arrangement is obtained.

The minus 8221 undersie from the Vibrating Screen is divided to feed two identical, parallel jigging circuits, each consisting of l68243x 248243 Duplex Mineral Jig used for roughing and a I68243x 248243 Duplex Mineral Jig used as a scavenger. Automatic Density Discharge Control Valves on the hutches of the scavenger Mineral Jig provide a controlled, continuous, high-density feed to a l68243x 248243 Duplex Mineral Jig used for final cleaning.

A final, cleaned concentrate is produced by the two cleaner Mineral Jigs and also a middling product which is re-circulated back to the scavenger jigs. This procedure is preferable to the immediate regrinding of the middlings as it avoids the further reduction of relatively pure chrome particles which are bound to be present.

The tailing from the scavenger Mineral Jig is directed to a 308243x 138242 Simplex Cross-Flow Classifier which discards a waste product as a final tailing at minus 65 mesh and the sand product is returned to the rod mill for further grinding. A SRL Sand Pump is used to pump the Mineral Jig Tailings to the Cross-Flow Classifier.

Chromite is an oxide mineral composed of chromium, iron, and oxygen FeCr2O4. It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or weathering.

Chromite can be challenging to identify. Several properties must be considered to differentiate it from other metallic ores. Hand specimen identification of chromite requires a consideration of color, specific gravity, luster, and a characteristic brown streak. The most important clue to identifying chromite is its association with ultrabasic igneous rocks and metamorphic rocks such as serpentinite.

Magnesium frequently substitutes for iron in chromite. A solid solution series exists between the mineral chromite FeCr2O4 and the isomorphous mineral magnesiochromite MgCr2O4. Intermediate specimens can be rich in iron Fe,MgCr2O4 or magnesium Mg,FeCr2O4. For convenience in communication, these minerals are often referred to collectively as chromite.
