Research on New Fluoride-Free Flotation Process of Feldspar Quartz and Industrial Test
In view of the difficulty of selling feldspar product in Yichun tantalum niobium ore due to the change of ore properties and the impact of feldspar product on the market,a new fluorine-free flotation process of feldspar quartz was explored with coarse feldspar as research object.The test results show that the new fluorine-free flotation process of feldspar quartz with completely removal of iron by floatation-quartz floatation in alkaline enviroment-feldspar floatation in acid environment can obtain high-quality feldspar concentrate with Al2O3 more than 16%,K2O+Na2O more than 10%and quartz concentrate with SiO2 grade of 95.04%,whiteness of 94.40%.On the basis of laboratory experiment,the industrial experiment is conducted,and the efficient separation of feldspar and quartz is basically realized,which can be used as the basis for the production of high quality feldspar and quartz in the concentrator.
