Phosphorite Flotation Equipment Production Line

Solution 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.

Solution Appliion

Phosphorite Flotation Product Line is applied for complex structure phosphorite with fine particle distribution closed embeddedness relationship difficult monomer dissociation etc.

Solution Description

Flotation ProcessDirect 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 ProcessMainly 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 ProcessIn alkaline conditions double-reverse flotation makes the silie surface positively charged and the anionic collector separates minerals meaning floating dolomite firstly and then reverse floating silie the product is heavy concentrate in groove the production line can be carried out at normal temperature and coarse grain condition.

Solution 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. es comparison as follow

By this technical reformation the technology principle was more reasonable the non-alkali Process no pollution to the environment the normal temperature condition could effectively reduce the cost.
