这种可使中、低品位硅藻土原土优选为优质精土的选矿工艺,是由大理州硅藻土研究所研制成功,经过小试、中试及工业生产试验。该工艺可将腾冲、洱源等地的中低品位硅藻土原土优选为优质精土。目前,准备开发洱源县、宾川县境内硅藻土矿及用高品质精土加工成硅藻土成品。 该工艺技术要点是:原矿土采集后,经擦洗加水成矿浆。进行负压爆破后使之与硅藻土共生的杂质分离。经超声波振荡使杂质处于运动
This can make medium and low-grade diatomite native soil is preferably high-quality fine soil beneficiation process, developed by the Dali Diatomite Institute, after a small test, pilot and industrial production test. The process can Tengchong, Eryuan source of low-grade diatomite native soil is preferably high-quality fine soil. At present, it is planned to develop diatomite mines in Eryuan County and Binchuan County and to process diatomite finished products with high-quality fine earth. The process technology points are: After the original ore collected, scrubbed water slurry. After the negative pressure blasting and diatomite symbiotic impurities separated. The ultrasonic vibration in the impurities in motion
