Research on tourmaline of huapi ditch, yichun city, helongjiang province

摘要

Tourmaline is the floorboard of the mineral tourmaline family with piezoelectricity and thermoelectricity. In 1989, Japanese scholars Kubo found tourmaline spontaneous permanent electrode, which led to a new boom of tourmaline development and research. Tourmaline, as the prospect of new mineral materials, has the attention of the scientists from multiple disciplines and has obtained great development in environmental protection, electronics, medicine, chemical industry, light industry, architecture and other fields. The domestic research on tourmaline resources development and utilization is limited. The mineral dressing method are mainly two kinds: magnetic separation and flotation separation. For this experiment, the magnetic separation and flotation comparison tests about tourmaline of Huapi ditch, Yichun city, Heilongjiang province have been carried out respectively, and the flotation separation achieves better results than the magnetic separation. The flotation part conducts the test to contrast the cationic collector and the anionic collector. the test results show that the results is better when closed-circuit uses the anionic collector sodium oleate as collector, and the study gets concentrate (B_2O_3) grade is 8.47%, the recovery of flotation concentrate is 83.77%.
