Hematite ore intro

Hematite iron ore deposits are currently exploited on all continents except Antarctica, with the largest intensity in South America, Australia and Asia. Most large hematite iron ore deposits are sourced from altered banded iron formations and rarely igneous accumulations.

Hematite iron is typically rarer than magnetite bearing BIF or other rocks which form its main source or protolith rock, but it is considerably cheaper to process as it generally does not require beneficiation due to its higher iron content. However, hematite ores are harder than magnetite ores and therefore require considerably more energy to crush and grind if beneficiation is required. Hematite ores can also contain significantly higher concentrations of penalty elements, typically being higher in phosphorus, water content (especially pisolite sedimentary accumulations) and aluminium (clays within pisolites). Export grade hematite ores are generally in the 62–64% Fe range.

Hematite iron ore beneficiation equipment supplier

SBM Company as a manufacturer of hematite mining and crushing equipment has been focusing on hematite iron ore localization solution especially hematite beneficiation plant. Except for the main iron ore mining countries such as China, Australia, Brazil, India, Russia, Ukraine, South Africa, Iran, USA, Kazakhstan, Sweden, etc, SBM Company has designed a whole series of iron ore mining solution as well as iron ore mining equipment such as primary jaw crusher, secondary cone crusher, fines powder mill, vibrating screen, in other iron ore mining countries such as Vietnam, Indonesia, Malaysia, Pakistan, Nigeria, etc.

Hematite ore beneficiation processing

The principal hematite iron ore beneficiation course of action incorporates:gravity separation,flotation,sturdy magnetic beneficiation or mix many beneficiation process,and one more method is magnetization roasting and after that weak magnetic separation. The early hematite iron beneficiation largely made use of the gravity separation course of action,and also the key machines are:jigger,centrifugal separator,spiral chute,spiral washing machine,shaking table etc. For the reason that some other beneficiations’ production capacity was small,the grade immediately after processing was low,recovery ratio is low and then was dumped as time goes on.

Hematite Iron ore crusher and Hematite iron ore grinding machine will be the very first step in Hematite iron ore processing plant. Ore crushed by means of the thick, the block is no more than 1m, and then through the medium and fine crushing and screening ore particle size less than 12mm into the final item sent to the grinding grooves. Hematite ores in large lumps should be sized into required dimension through primary crushing and secondary crushing. Grinding process would also be conducted if necessary in the following steps.

Hematite Beneficiation Process

Hematite is weak magnetic. It contains mainly Fe2O3, concluding Fe70 %, O 30%, which is the major iron ore. Based on the test report of ore provided by customer, we designed this hematite dressing technics: three stages crushing----one stage milling----two stages magnetic separation---- dehydration----final product. Using this technics, we can improve the Fe content from 40% up to 65%. And the ferric oxides recovery ratio is about 80%.

1.Hematite ore crushing: in this stage there are also three steps, the hematite ore may go through primary crushing, secondary crushing and fine crushing. Hematite primary crushing equipment includes gyratory crusher, jaw crusher, hammer crusher etc. Hematite secondary and fine crushing plants mainly include cone crusher, ball mill, vertical mill, ultrafine mill etc.

2.Main operation steps in the whole hematite beneficiation process include sorting, gravity separation, floatation, magnetic separation, electrostatic separation, chemical mineral processing etc. There are many plants involves in hematite beneficiation process, such as flotation equipment, magnetic separator, electrostatic separator etc.

3.The treatments of refined hematite mineral include dehydration, tailing disposal, backwater etc. Thickener and dryer are important plants in this stage.
