Study on Beneficiation of a Low Magnesium Phosphate Weathering Ore from Tian Ning

Abstract:

Weathered phosphate ore is an important part of phosphate ore resources, it contains a huge reserves of this resources in Yunnan regions, and its reserves over 200 million tons. With the gradual consumption of the rich phosphate ore resources, recycling for weathering phosphate ore is receiving more and more people's attention. In this study, using Tian Ning weathered low magnesium phosphate ore which from Yunnan Dianchi Lake area as the study object, and based on its ore properties established a experimental program of pre-desliming with cyclone and then flotation. The P₂O₅ loss rate under 20% on the desliming operation, then using a single positive flotation process at room temperature, ultimately obtained a test indicators of phosphate concentrate of P₂O₅ grade of 29.98% and P₂O₅ recovery of 95.02%, which is a foundation of development and application for Tian Ning weathering phosphate ore.
