MINING EQUIPMENT FOR SPECULARITE IRON ORE UPGRADING-IRON ORE DRESSING PLANT . Similar to hematite and limonite iron ore, specularite is also kind of weak mineral and its possible beneficiation method can be gravity separation and magnetic separation. Gravity separation is mainly for specularite of coarse embedded size while magnetic separation ...

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of ...

A process for upgrading low-grade magnetite-containing iron ore with minimum fine grinding. The dry ore is first comminuted to between about three-fourths inch and 10 mesh particle size and magnetically separated. The dry tailing is discarded and the concentrate is ground to between about 20 and 100 mesh and again subjected to dry magnetic separation.

For punctate low grade mercury processing, gravity separation-flotation combined process may be used for dressing. Here let's take a look at the picture of mercury ore: From the picture, we can see 3 different mercury stone, among which the separation of block mercury stone and mottled mercury ore dressing is relatively simple.

1. Single weakly magnetic iron ore It includes hematite, siderite, limonite and hematite (Specularite) – Siderite of sedimentary metamorphic, sedimentary, hydrothermal and weathering deposits. This kind of ore dressing production practice is less, because of the variety of minerals, dissemination of a wide range of particle size.

Among all the washing & dressing plants of hematite ores of the day, hematite ore dressing plants and gravity concentration draft of specularite play important roles.

Hematite (or haematite) Hematite is the most important ore mineral of iron. It is an oxide mineral and is found in a variety of colours, with red, orange and brown occurring when the iron in hematite begins to rust. There are also several forms of hematite, some of which are: kidney ore, a massive, botryoidal (lumpy) or reniform (kidney shaped) form; specularite, a micaceous (flaky) form ...

Abstract：Ore dressing test was conducted for processing a mixed ore of magnetite and specularite from Anhui Province. The process adopted in the test consists of staged grinding, low intensity magnetic separation, screening, medium intensity magnetic separation, high intensity magnetic separation, gravity separation and reverse flotation.

Fluorine-bearing iron ore is unique and complex. Serious preheating and roasting problems of fluorine-bearing iron concentrate pellets appear during the industrial production by the grate-kiln process. Besides, specularite has low hydrophilicity, undesirable particle size and shape, dense and smooth particle surface and poor assimilation performance.

In Figure 9.12, SLon magnetic separators are used for processing a specularite ore containing about 35% Fe. The run-of-mine ore is mainly composed of specularite and quartz. The ore is first ground down to about 85% -75 μm using ball mills. SLon magnetic separators are then used for roughing and cleaning to extract the specularite particles.
