Product Description
Phosphorite Flotation Equipment Production Line
Process Introduction
According to different ore properties of phosphate, Xinhai designs many processes for it such as flotation, gravity separation, chemical leaching, combined dressing, photoelectric sorting, etc. Flotation is widely used in phosphate including direct flotation, reverse flotation, reverse flotation and flotation, and double-reverse flotation process.
Application
Phosphorite Flotation Product Line is applied for complex structure phosphorite with fine particle distribution, closed embeddedness relationship, difficult monomer dissociation, etc.
[Process Description ]
Direct flotation inhibits gangue minerals by effective inhibitors, and the phosphorus mineral is enriched in foam by collecting agent. This process is suitable for low grade phosphate ores including magmatite type apatite and sedimentary metamorphic type phosphorite ore
Reverse Flotation Process
Mainly used for the separation of phosphate and dolomite; Dolomite is collected with fatty acid collector in weak alkaline medium, and the phosphorus mineral is enriched in the groove. The biggest advantage of reverse flotation process is the realization of the normal temperature flotation.
Double-Reverse Flotation Process
In alkaline conditions, double-reverse flotation makes the silicate surface positively charged, and the anionic collector separates minerals meaning floating dolomite firstly, and then reverse floating silicate; The product is heavy concentrate in groove; The production line can be carried out at normal temperature and coarse grain condition.
[ Case ]
A phosphorite in Yunnan belonged to low grade siliceous and calcareous collophanite with fine particles and close distribution of useful minerals and gangue minerals. The plant adopted flotation and reverse flotation process, but there were some defects in the flotation reagent dosage and high temperature. In order to reduce the cost, the plant authorized Xinhai to take technical reformation. Xinhai used the double reverse flotation for phosphorite after the test. Xinhai achieved 40% concentrate grade when the crude ore grade was 18.55%. Indexes comparison as follow:
| Comparison of Reformation | Process | Grade of Phosphate Concentrate
/% | Recovery Rate of Phosphate Concentrate
/% |
| Before Reformation | Flotation and Reverse Flotation Process | 29.74 | 70.27 |
| After Reformation | Double-Reverse Flotation Process | 32.58 | 72.18 |
