Bond Work Index Formula-Equation. 2 The Bond Work Index is a factor that measures the energy consumed in size reduction operation of the ore. The Bond''s Work Index equation is W=WI (10 √P80 -10 √F80) where. W= the energy input (Work input) per ton, kwh metric ton.Jan 28, 2014 The results showed improved properties of iron ore pellets at an optimum Blaine number (2150 cm 2 g) but, reduction degradation index was found to be very poor for the given ore. Further investigation showed that when MgO containing flux viz. pyroxenite was added, the reduction degradation index and swelling index of the pellets were improved.
Bond index is useful in designing of grinding system in mineral processing.

It was developed by Fred Bond in 1952 and modified in 1961 (JKMRC CO., 2006).This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding,.
Bond Work Index Tables (Wi) - Free download as PDF File (.pdf), Text File (.txt) or view presentation slides online. Here there are given tables from various sources for the Bond work index values of mining materials (ores, industrial minerals and rocks). These work indexes can be used for the determination of tumbling mills (rod, ball mills) power.Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel industries.
