Limonite crusher is applied for crushing limonite raw materials into small size with industrial application. According to the working styles, NFLG can supply you stationary limonite crusher and mobile limonite crusher for sale all over the world in mining industry.
Limonite Introduction
Limonite is a minor ore of iron. It is also used as a stain in the paint industry. The widespread and common hydrated iron oxide mineral limonite, Fe(OH)ánHMO, is a minor ore of iron and a source of ocher and umber pigments.
Currently used for unidentified massive hydroxides and oxides of iron, with no visible crystals, and a yellow-brown streak. ‘Limonite’ is most commonly the mineral species goethite, but can also consist of varying proportions of maghemite, hematite, lepidocrocite, hisingerite, pitticite, jarosite group species, etc.
Having no crystalline form and containing highly variable amounts of water, limonite forms yellowish earthy coatings or brown to blackish, stalactitic, grapelike, or fibrous masses and concretions.
1. Hardness is 4-5.5, luster is silky or earthy, streak is yellowish brown
2. Specific gravity is 2.7-4.3.
3. Much of the material formerly thought to be limonite now is known to be goethite, which is crystalline and has a definite chemical composition, HFeO2.
Limonite beneficiation process flow
The limonite ore beneficiation process includes limonite ore crushing, magnetic separation and flotation. This passage tells you how to produce iron ore concentrate and the limonite beneficiation equipments.
Limonite iron ore beneficiation equipment
Iron ore crushing equipment
1. Primary crusher (<30mm): jaw crusher is used as primary crushing equipment in the complete whole ore processing plant. PE series jaw crusher is one of the most popular stone crushing equipment in mining industry ideally suitable for primary crushing. The highest anti-pressure strength of crushed material is 320Mpa. Our design and production are of high position both at home and abroad.
2. Secondary crusher (<10mm): cone crusher ore fine jaw crusher. Limonite cone crusher mainly includes Limonite spring cone crusher, CS series Limonite cone crusher, hydraulic cone crusher etc. JCE type jaw crusher is usually used as fine jaw crusher in Limonite ore crushing process.
Iron ore grinding equipment : Wet ball mill Iron ore concentrate dressing equipment: Magnetic separator, classifier, thickener, reverse flotation machine
Limonite crushing and grinding
Very low grade limonite iron ore in large lumps need to crush and grind, in order to be sized into required dimension. The common crushing machines used in iron ore beneficiation plant are jaw crusher as primary crusher, cone crusher or fine jaw crusher as secondary crusher. The iron ore materials of required size after screening then pass to the flotation process. Wet ball mill is used to grind limonite ore in powder, of which 70% is 0.076mm is size.
The common iron ore crushers are jaw crusher (for primary crushing), cone crusher or fine jaw crusher (for secondary crushing). Materials in large lumps are reduced by crushers into small particles and then separated by vibrating screen . Large ones return to crushing process, while small ones pass to milling step.
In addition to supply limonite ore crusher and limonite ore grinding mill , we also offer you many related optional equipments such as vibrating feeder , vibratory screen, belt conveyor and sand washing machines. Our other industrial machines are also famous in mining industry or stone crushing process such as vertical roller mill, Raymond mill , ball mill, impact crusher , mobile crusher , hammer crusher , sand making machine , crawler type mobile crusher and so on.
High intensity magnetic separation
Limonite ore after classifier passes to high intensity magnetic separator. High iron content (+47.69%) limonite ore is moved to thickener and low iron content one to high intensity magnetic scavenger separation. the middling are mixed with rough meddling for thickening process, while the rest ones are discharged as tailings.
First thickening, classification and grinding
After first thickening, low iron content (-47.25%) limonite ore is moved to ball mill to be grinded into finer powder (90% < 0.067mm). The fine ore powder is mixed with middlings after first thickening for second thickening process.
Second thickening
The second thickening is conducted for further upgrading of limonite iron ore. The product with iron content lower than 40.08% returns to scavenging, and the one higher than 49.04% passes to reverse flotation.
Reverse flotation
Reverse flotation includes rough flotation and clean flotation, through which Limonite iron ore would be greatly upgraded. The iron concentrate obtained is of 56.73% in content. The middlings return to magnetic flotation, forming a close-circle process.
Limonite mobile crusher for sale
Limonite mobile crusher also known as limonite portable breaker mainly including five types according to the equipped machines in the crushing station such as jaw type mobile crusher, cone type mobile crusher, impact type mobile crusher, VSI type mobile crusher and crawler type mobile crusher etc.
