Peru daily processing 6,000 tons of potassium feldspar

Project Introduction

Capacity: 10t/h 
Processed material: slag
Daily operation:8 hours


Equipment Configuration

This project is a daily 6,000-ton EPC project signed by our company in 2016 with Peruvian customers. K-feldspar has the characteristics of low melting point, long melting interval and high melt viscosity. It is widely used in ceramic blanks, ceramic glazes, glass and electric porcelain. , industrial materials such as abrasive materials and potassium fertilizer.

Project Introduction

Graphite ore can be divided into crystalline graphite, flake graphite and graphite ore with a variety of gangue. The graphite ore beneficiation process is mainly for the graphite ore with different crystal forms, such as graphite ore, pyrite or mica. It adopts multi-stage grinding multi-stage flotation and re-election flotation combined with two beneficiation processes. Because crystalline graphite has natural floatability, flake graphite has good floatability. Therefore, for these two kinds of graphite ore, hanfa usually adopts multi-stage grinding multi-stage flotation method for beneficiation. The reason why the multi-grinding and multi-floating method should be used is to protect the graphite scales, ensure that the scales are not damaged, and ensure that the quality of the concentrate meets the requirements. In the multi-stage flotation process, the application of flotation reagents: collectors should use diesel, heavy oil, kerosene, sulfuric acid, phenols, etc.; foaming agents should use No. 2 oil, No. 4 oil, butyl ether oil and Ether alcohol and the like.

Technological Process

The K-feldspar ore is first passed through the feeder, and then broken through the E-break, then broken with fine E, broken and sieved with a vibrating sieve. The iron-containing material in the K-feldspar ore is sorted by a dry magnetic separator. Then, the sorted K-feldspar ore remains and is stored in the silo. The K-feldspar mine enters the feeder from the silo, and then is fed by the feeder to the scoring mill. It is then sieved using a spiral classifier or a high frequency sieve. K-feldspar processing is divided into two steps of rough selection and selection. Rough selection: K-feldspar materials sieved by spiral classifier or high-frequency sieve are separated by magnetic separator and then separated from iron and processed. Finish the finished product. Selection: After the potassium feldspar material is sieved by a spiral classifier or a high-frequency sieve, the iron is removed by a magnetic separator, and then flows to the next process, that is, the potassium feldspar material after the iron removal flows into the thickener for precipitation and filtration. After filtering, it is the finished product.

Crushing stage

Through vibrating feeder, large raw ores are continuously fed into PE jaw crusher for primary crushing, then into PEX jaw crusher for secondary crushing, after into circular vibrating screen for screening work. For those larger crushed ores, they would be delivered back to PEX jaw crusher again for continuous crushing. While, for those qualified ones, they will enter into storage bin through conveyors. 

Grinding and classifying stage

Crushed copper-molybdenum ores in storage bin are conveyed into ball mill for being ground. The ground powders will enter into spiral classifier for being classified and washed. 

Flotation separation stage

For those qualified copper-molybdenum ore powders, they are conveyed into mixer barrel and added with certain amount of drugs. After the complete mixing and agitation, these powders will enter into flotation machine for dressing work. 

Drying stage

Copper-molybdenum ore concentrates produced after the flotation stage are relatively wet. So, they need to subside in thickener and are dried in dryer. Finally, dried finished concentrates will be produced.
