Abstract
Un método de flotación descrito en esta especificación incluye un paso de flotación de arsénico de someter una suspensión mezclada con minerales que contienen minerales de cobre y minerales de arsénico a flotación sin la adición de un colector o con la adición de un colector en una cantidad de 10 g o menos por tonelada de los minerales para obtener flotadores que contienen los minerales de arsénico y relaves que contienen los minerales de cobre.A flotation method described in this specification includes an arsenic flotation step of subjecting a mixed slurry containing copper ores and arsenic minerals to flotation without the addition of a collector or with the addition of a collector in an amount of 10 g or less per ton of minerals to obtain floats containing arsenic minerals and tailings containing copper minerals.
