Why fines and lumps make a difference. Sinter production is done by mixing the fine iron ore with a binder (clay) and sometimes a flux (limestone), then heating it to about 1200 degrees celsius to produce a hard biscuit or pelletshaped product ranging from the size of a large pea to a small briquette. There are some advantages to using fines,...
The average iron content of pellets is 63 percent. Process Description25,41 Processing of taconite consists of crushing and grinding the ore to liberate ironbearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore concentrate.

Historically, Iron Ore reached an all time high of in February of 2011 and a record low of 37 in December of 2015. Trading Economics members can view, download and compare data from nearly 200 countries, including more than 20 million economic indicators, exchange rates, government bond yields, stock indexes and commodity prices.
Iron ore fines are characterized on a physical basis by variations in particle size, shape, density, porosity, surface area, roughness, and wettability. Furui et al. (1977) divided iron ore particles into nucleus particles of + mm size, intermediate particles of − + mm size, and adhering particles of − mm size. As the intermediate particles can act as neither nucleus particles nor adhering particles, they .
Iron Ore Lump. The Iron Ore contains lumps of different size which the biggest could be more than 1 Meter across and the smallest is about 1 Millimeter. The blast furnace, however, needs lumps between 7 and 25 Millimeters, so the ore must be crushed to make smaller size particles. When iron ore is crushed and divided to lump and fines parts,...
