title = "Surface behavior of iron sulfide ore during grinding with alumina media",
abstract = "This research was conducted to study the oxidation and surface modification of pyrite in an inert mill and alumina grinding media at different pH values. The extent and progress of the oxidation function of milling time, by measuring some physicochemical variables, zeta potential (ZP), infrared analysis and monitoring. The results indicate pyrite oxidation during grinding, releasing iron and sulfur ions to the solution increasing its concentration with the initial pH and the milling time, the ORP and DO decrease the grinding time, on the other hand presents negative values ZP pH of 9, 11 and 12, whereas at pH 5, 7 and 13, the ZP is positive, FTIR generally detect the presence of free sulfate ion molecule 1084 cm-1, goethite with the absorption band at about 794 cm{"}, also occurs in a band assigned to 470 cm-1 lepidocrocite oxy iron hydroxide γ-FeOOH, nucleated species or fonned during milling.",
