MANGANIFEROUS IRON ORES.

The content of manganese in the manganiferous iron ores ranges from 1 to 30 or 35 per cent, and the iron from 20 to 50 per cent or more. The silica usually ranges between 8 and 16 per cent in the low-phosphorus ores but is lower in the high-phosphorus ores. Phos phorus ranges generally from 0.06 to 0.10 per cent in the low-phos .15

Removal of phosphorus

A new approach of removing the phosphorus-rich phase from high-phosphorous iron ore by melt separation at 1573 K in a super- gravity field was investigated. The iron-slag separation by super-gravity resulted in phosphorus being effectively removed from the iron-rich phase and concentrated as a phosphorus-rich phase at a temperature below the melting point of iron.

Phosphate Rock

Apatite was the main phosphorus mineral in the iron ore and the wastewater contained native sulfur-oxidizing bacteria. The sulfur-oxidizing bacteria are not as sensitive to organic matter as the iron-oxidizing bacteria and either used the organic matter as a carbon source or were not inhibited by its presence. Between 83% and 87% of the phosphorus was bioleached from the iron ore in both experiments

Phosphate Rock

The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world.

An Overview of Phosphates and Their Uses

Phosphates occur naturally in certain foods, but when added to processed foods they can have serious health effects if large amounts are consumed. Phosphate food additives have been shown to stimulate lung cancer development. High phosphate content in processed foods can also affect renal and cardiovascular function.

Amazing Uses of Hematite You Probably Didn't Know About

It supplies us with large amounts of iron as its iron content is as high as 66 percent. Usually, any type of iron ore is processed first to get rid of all its impurities before it is fed into the blast furnace for conversion into iron, but because the concentration of iron in hematite is so high, it can be added to the furnace directly without processing it first.
