Abstract：

The　effect　of　sodium　ethylenediamine　phosphate　on　sulfide　flotation　of　cuprite　was　investigated　by　single　mineral　flotation　tests.　The　influence　mechanism　of　sodium　ethylenediamine　phosphate　for　sulfide　flotation　of　cuprite　was　studied　by　means　of　X-ray　photoelectron　spectroscopy,　Zeta　potential,　adsorption　energy　of　reagents　on　mineral　surface　and　adsorption　capacity　of　collector.　The　results　showed　that　the　sodium　ethylenediamine　phosphate　can　increase　the　content　of　copper　and　sulfur　elements　on　the　surface　of　the　sulphide　cuprite　mineral,　increase　the　negative　value　of　the　adsorption　energy　of　HS-　on　the　surface　of　the　mineral,　and　make　the　sulphide　reaction　easier　occur,　thus　improving　the　sulphide　effect　on　the　surface　of　the　mineral,　increasing　the　adsorption　capacity　of　the　mineral　surface　collector,　and　improving　the　recovery　rate　of　sulphide　flotation.　©　2020,　Editorial　Department　of　Journal　of　Northeastern　University.　All　right　reserved.
