Iron Ore Processing Plant Design

Iron Ore Processing Plant Design

Details of this product

Abstract: There are many different types of iron ore, and there are some differences between different iron ore Processing plant Design, this article will take the Siderite iron ore for example, talk about the Iron Ore Processing Plant Design. Hope it will be useful for you.

Physical Properties Of Siderite Iron Ore

Siderite iron ore crystals mostly rhombohedral shape, short columnar or scalenohedral shaped aggregates often grainy, earthy, dense block. In the deposition layer nodular Siderite iron ore spherical or nearly spherical, hemispherical Aphanitic partial colloid, said ball Siderite iron ore. In some marsh sediments, there are amorphous or Aphanitic gelatinous Siderite iron ore, said glue Siderite iron ore. Siderite iron ore in the oxidation zone of the unstable, easily decomposed into water hematite, limonite gossan made​​. When a large gathering of Siderite iron ore as iron ore. Generally used as the iron industry requirements (mass fraction) of ore: Boundary grade TFe≥20%, industrial grade TFe≥25%.

Siderite Iron Ore Processing Plant Design

Siderite iron ore ore commonly used method is to re-election, high intensity magnetic separation. For different types of Siderite iron ore, its various sorting methods: a single coarse-grained disseminated Siderite iron ore (including containing hematite, limonite) and specularite for re-election (jigging, heavy media), strong magnetic separation, magnetic separation, and its co-firing process; fine disseminated for roasting, high intensity magnetic separation, flotation or magnetic joint process; for magnets – Ling (red, brown, mirror) iron ore, generally weak magnetic separation and roasting, re-election, a parallel process combined intensity magnetic separation or flotation process in series, or magnetic roasting with other methods, Processing process is more complicated.

Siderite Iron Ore Processing Plant Feasibility

Siderite iron ore density of 3.7 ~ 4.0g / cm3, less dense than other iron minerals; than magnetic coefficient 35 ~ 150 × 10-9m3 / kg, magnetic weak magnetic field on the high requirements; Also, most embedded cloth fine granularity, complex composition, low grade, is refractory ore resources. Theoretical grade Siderite iron ore 48.2%, partly due to Mg2 + Siderite iron ore and Mn2 + replaces the iron ions to form isomorphous magnesium, manganese, Siderite iron ore, so the theory grade usually between 32% to 48%, so Iron Ore Processing Plant difficulties. Some steel companies because of Siderite iron ore from its own mines, in order not to waste of resources, barely fit into the Siderite iron ore iron powder concentrate is used, but with the amount of 7% to 8% will significantly affect the sintering mine strength. Therefore, Siderite iron ore typically through magnetic roasting makes FeCO3 into Fe3O4, then recovered with a method for recovering natural magnetite. Has been used for Iron Ore Processing Plant iron and steel parts bonanza less than 10% of total reserves of Siderite iron ore, mostly lean ore mining has not been utilized.
