The selection of physical design parameters and the scheduling of the ore and waste extraction program are complex engineering decisions of enormous economic significance. The planning of an open pit mine is, therefore, basically an exercise in economics, constrained by certain geologic and mining engineering aspects. A bench may be defined as a ledge that forms a single level of operation

The chemical composition (by mass) of the chromite ore was: % Cr2O3, % Fe2O3, % FeO, % MgO, and % Al2O3. The slag samples were synthetically prepared in the composition range 50–65% SiO2, % CaO, 510% MgO, and 1020% Al2O3(by mass). The basicity ratio (CaO/SiO2) varied between and
Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world''s chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years. It is mostly used for making stainless steel and other metal alloys.

Figure Process flow chart for execution of investigation Based on the literature review process flow chart have been prepared to accomplish the above objectives is given in figure Jha Production Department International Journal of
The chromite ore in the Chickay Mine is in the form of a vein of complicated shape. Due to depletion of high grade chromite ore, and the presence of a large amount of lowgrade ore in the area, it was necessary to come up with a suitable mineral processing technique to upgrade these lowgrade ores together with the leftover fines from the previous chromite mining operations. The flotation

tial tonnages of chromite, but the ore has a low Cr2 03 content and is high in iron; if the United States'' industry were to be come dependent on it, major shifts and inefficiencies in metal lurgy would be inevitable (Thayer, 1973). Ultramafic rocks of the alpine peridotite type are common in both the Western and Eastern United States, and diligent search by prospectors over the last 100
Chromite mining in Turkey started in 1850; since then, Turkey has had an important role in the world chromite market. Turkey produces chromite ore and ferrochrome. It is estimated that Turkey has produced about 45 metric tons of chrome ore. Chromite production is mainly exportoriented. Turkey has one chrome and two ferrochrome chemical plants.
The chromite ore containing rock will be drilled, blasted, removed and loaded onto large trucks for hauling to the crusher and ore processing facility Underground Mining The transition to underground mining will be considered once it is necessary to extract rock from greater depths. The underground mine will be reached from the bottom of the open pit. Blast hole stopping methods will be used

Chrome ore processing chromite deposits are mined by both underground and surface techniques much of the ore is rich enough to be used directly for production of ferrochromium, a rich, lumpy ore containing more than percent cro and having a chromiumiron ratio greater than is preferred, but ores with a lower ratio and as little as
Chromite is a mineral that is an iron chromium has a chemical formula of FeCr 2 O is an oxide mineral belonging to the spinel element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4). A substitution of the element aluminium can also occur, leading to hercynite (FeAl 2 O 4).
Several operating parameters influencing the floatability of the Sudanese chromite ores were investigated. These include the collector and depressant dosages, pulp pH, and conditioning time. From an ore feed grading % Cr 2O3, a chromite concentrate of % Cr 2O3 with recovery of % could be obtained by flotation at collector dosage of kg /t, pH 9, 2 min conditioning time
