Hematite and quartz microflotation using millet starch as depressant
Autor: André Carlos Silva, Débora Nascimento Sousa, Elenice Maria Schons Silva
Publikováno v: REM: International Engineering Journal, Vol 74, Iss 1, Pp 107-116 (2021)
Abstract Brazil is among the world's largest iron ore producers. The standard concentration method is reverse cationic flotation using amines, and their derivatives, such as quartz collector and corn (as either grits, flour, or starch) as the hematit
