Beneficiation of bastnasite-monochlorite mixed type ore

Inner Mongolia metamorphic deposition area of Baiyun'ebo - fluorine, sodium account type Nb - rare earth - iron contains more rare earth mineral deposits, wherein the industrial value is bastnaesite and monazite, the ratio of the two (9:1 ) ～(6:4) fluctuates between. Raw ores containing REO5% ~ 6%, other minerals are mainly hematite, magnetite, rare metal ore, barite, calcite, dolomite, quartz, feldspar dozen gangue minerals. There are six main processes for mineral processing for the characteristics of ore :

1 priority flotation iron process;

2 mixed flotation-foam separation iron process;

3 preferential flotation fluorite -rare earth-iron process;

4 semi-priority semi-mixed flotation iron process;

5 weak magnetic-semi-priority semi-mixed flotation-re-election-flotation combined process;

6 Weak magnetic-strong magnetic-flotation combined process.

The following figure shows the weak magnetic-strong magnetic-flotation combined process. The rare earth concentrate of this rare earth concentrate can reach more than 60%.
