Drilling in the benches of open pit mining is done for production of iron ore with mechanized drills specific for each mining method. The main objective of drilling operations is to create a hole of suitable diameter, depth and direction in rock for explosives to be placed for blasting activities.


method of transportation is an iron ore slurry pipeline. 4.1.2 Iron Ore Beneficiation Iron ore occurs naturally in a variety of forms, from sand-like iron fines to solid rock masses. Crude ore, or ore mined in the natural state, seldom occurs in a pure state and requires some form of beneficiation.


The success in a mining operation depends on the accuracy of the reserves evaluation as well as the distribution of ore grades. Geostatistics techniques such as OK and IDW are widely used for ore grade estimation (Tahmasebi and Hezarkhani 2010)..
