A step change in mining productivity AusImm Bulletin

Alternatively, differential blasting can induce a size difference between high grade and low grade zones in the pit, with the low grade coarse fraction removed by screening. CRC ORE has tested a wide range of ores and has developed protocols to place an ore on response ranking curves to assess coarse separation potential relative to other ores.

High grade hematite direct shipping ores (DSOs) generally only require crushing and screening to meet the size requirements of lump (typically between 6 and 30 mm) and fines (typically less than 6 mm) products. Low grade hematite ores require additional beneficiation to achieve the desired iron content, but the comminution of these ores still

Ore

The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.

What Is Iron Ore Sintering? (with pictures) wisegeek

Sep 18, 20190183;32;To understand iron ore sintering, it is necessary to first understand certain aspects of raw iron ore. Raw iron ore is found throughout the world and is, in fact, one of the most prevalent elements on earth. Mining operations pull raw ore from the earths crust, separating it into high grade and low grade, based on how much raw iron is present.
