iron ore use in drilling
The drillers have to tackle three main ore types; laminated iron ore, drilled at 120 –130 m per shift (using the PV-271 and single-pass DTH drilling), loose conglomerate, and compact conglomerate. Very abrasive phyllites and quartzites are also encountered as well as "soft" iron on the Mokaning development property.

Open-Pit Mining | Method and Process | Epiroc US
Open-pit mining technology. Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.
The six main steps of iron ore processing
The drilling principle is to use a high pull down force (weight-on-bit), rotate the drill bit, and blow the rock cuttings to the surface with …
BlastHole Drilling Introduction
In smaller holes, it is most common in softer rock formations. The drilling principle is to use a high pull down force (weight-on-bit), rotate the drill bit, and blow the rock cuttings to the surface with compressed air. Hardrock drills typically use the Rotary method to drill blastholes from 200 mm (7 7 /8") to 311 mm (12 ¼") diameter.
Iron Ore Statistics and Information | U.S. Geological Survey
Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries. The seven largest of these producing countries ...

Deep Learning Approach at the Edge to Detect Iron Ore Type
The central proposal of our work is the development of this detection of the risk of collapse of iron ore based on its image. Red carried iron ore with risk of avalanche has a brighter image, while material without risk tends to be more opaque; these are the main characteristics that allow the differentiation between the types of material and its …
