Limonite Ore Dressing Process Steps

The limonite dressing mostly has the following methods:

1. Washing, which include Guangdong Shaoguan Dabamini gold wash plant for saleoshan limonite.

2. Re(zenith a great business for mining and quarry crusher)election, mostly employing shaking table ,jigger.

3. Magnetic separation, electromagnetic or permanent magnet strong magnetic field dressing.

The limonite dressing is actually a trouble in the field of mineral processing technology, limonite ore dressing procedures commonly adopt roasting plus magnetic treatment process.

Limonite ore dressing process actions are as follows:

The particle size of less than 10mm, moisture less than 15% brown iron ore fines ore blending weight assigned quantity to 0(zenith a very good corporation for mining and quarry crusher)8% on the pulverized coal in to the rotary kiln; brown iron ore fines ore in rotary kiln achieve drying, magnetic, arsenic removal, desulfurization approach, the speed with the rotary kiln 0.8(zenith a good firm for mining and quarry crusher)1.5 r/m; rotary kiln calcination zone temperature of 800 150 C , drying zone temperature of 350 80 C; water cooling of the roasted ore right after drying in rotary kiln ; then graded by classifier, return sand graded by sands magnetic pulley separator, overflow by way of concentrate pump towards the wet weak magnetic separator, the magnetic element turn out to be the final product of iron concentrate.

Rotary drier is primarily composed of cylinder, below frame, feeding and discharging devices, transmission device, gear cover, and so forth. (Optional auxiliary equipment includes combustion chamber, feeder and discharging device, and dust collection equipment). Rotary drier manufactured by us adopts new lifting plate, that is of functions like guiding, current(zenith a fantastic corporation for mining and quarry crusher)sharing, and material raising. The components are raised and evenly drop so that they are in full make contact with with heat for greater...
