The potential iron loss in ore beneficiation of three hypothetical ores with a rich fraction consisting of haematite containing 1% Si and 67% Fe and having a fraction consisting of 70% SiO 2 and 10%, 15% and 20% Fe. In this calculation, the poor fraction is discarded and the iron loss is presented per ton of DR-pellet feed.

Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and flushed away. The iron ore magnetite, Fe 3 O 4, is ferrimagnetic. It can be separated from abundant deposits of taconite by grinding to a ...

The Platts Iron Ore Index is a benchmark assessment of the spot price of physical iron ore concentrate which is based on a standard specification of iron ore fines with 62% Fe, 2.25% alumina, 4% silica, and 0.09% phosphorus, among other …

Present beneficiation studies are oriented towards exploring the possibilities of upgrading Chiniot iron ore to produce iron concentrate for utilization as a feed in conventional blast furnace or direct reduction method to produce iron and steel. Materials and Methods Sample Preparation The core samples of seven drill holes of Chiniot iron ore

beneficiation of Indian iron ores. It helps in removal of adhering clay and silica to produce free flowing lumps and sand. But it has limitations in reduction of impurities and sometimes desired alumina/silica ratio is not achieved. The present beneficiation practice also generates fines and slimes varying from 10 to 25%.
