10TPH Feldspar Processing Plant In Nigeria

10TPH Feldspar Processing Plant

1. Crushing & Screening: jaw crusher, vibrating screen

Utilize rough jaw crusher, fine jaw crusher and vibrating screen to form a closed crushing circuit, so as to make 200mm rock ore down to 20mm. Thus, it makes sure the particle size of the material entering the grinding section is qualified.

2. Grinding section: ball mill, spiral classifier

Utilize ball mill and spiral classifier to form closed grinding circuit, so as to achieve more than 90% discharging size 200mesh(0.074mm). Thus, it makes sure the particle size of the material entering the flotation section is qualified.

3. Magnetic separation: magnetic separator

A two-stage magnetic separation process of low-intensity magnetic separation and high-intensity magnetic separation was used to remove magnetic minerals in feldspar ore to the maximum extent. Low-intensity magnetic separation can remove magnetite(Fe3O4), and high-intensity magnetic separation can remove hematite, limonite, ilmenite(Fe2O3).

4. Flotation section: flotation machine

The flotation process is used to remove impurities in the feldspar ore further, so as to obtain high grade feldspar concentrate.

5. Dewatering process for concentrate: thickener, disc vacuum filter machine

The dewatering process for the concentrate utilizes a thickener and disc vacuum filter machine. Use a slurry pump to send concentrate to the thickener, the overflow of thickener goes to a clear water pond, and the underflow goes to disc filer machine for dehydration. After being dehydrated by a disc filter machine, the moisture concentration is less than 10%.

6. Tailing dry discharging process: cone thickener, plate filter machine

All tailings are first pumped to cone thickener for adjusting the suitable concentration, the overflow of cone thickener go to recycled clear water pond, and the underflow go to plate filter machine for dehydration, finally the moisture of tailing is less than 10%, this is tailing dry discharging process.
