Abstract: In order to study the collection performance and mechanism of the etheramine collector DXY-1 on quartz， first a single mineral flotation test was carried out，and then the Zeta potential before and after the adsorption of the agent and mineral was detected and simulated by MS software. The test results show that the collector DXY-1 has a good collection capacity for quartz at room temperature，and the flotation recovery rate is best at pH=10，which can reach 98.0%. The CASTEP module based on MS software calculated the adsorption energy of collector DXY-1 on the surface of quartz minerals，which is negative and lower than the adsorption energy of OH? on the quartz surface，indicating that adsorption can occur and compared with OH? The collector DXY-1 has a stronger adsorption effect on quartz. Combined with the Zeta potential detection before and after the adsorption of reagents and minerals and the calculation results of MS simulated population numbers，it is shown that the adsorption methods of collector DXY-1 and quartz (101) surface are electrostatic adsorption and hydrogen bonding adsorption.
