Process and composition for the concentration of iron ore by froth flotation using a mixture of eterdiamina and etermonoamina

摘要

Process and composition for the concentration of iron ore by froth flotation using a mixture of eterdiamina and etermonoamina.This invention describes the process of cationic reverse flotation of iron oxide through the use of a eterdiamina premium of a etermonoamina,In a relationship of eterdiamina to etermonoamina 5: 1 to 99: 1, preferably of 9: 1 to 19: 1, as a way of optimizing the selectivity of the process.Seeking the maximization of the recovery in weight and metallic iron with the reduction of the content of SiO2 in concentrates generated.
