Flotation + magnetic separation on copper-bearing iron mineral
A large-scale iron mine in South America contains a certain amount of copper. One large-scale enterprise adopted a traditional process — crushing on site, dry separation for discarding non-magnetic ores. A large number of non-magnetic copper are discharged, the rest of copper is treated by flotation as the borderline sulfide.
Innovation points
-
01
There were recyclable non-magnetic copper minerals in iron ores, therefore, traditional process of dry separation for discarding non-magnetic ores was not adopted.
-
02
Due to the fragility of copper minerals, one stage of grinding and two stages of classifying were adopted. Enlarging the discharging particle size of ball mill and adding one stage of flash flotation in grinding and classifying circuit were to ease the argillization; adding one stage of flash flotation before roughing in flotation process was to separate the copper minerals with fragile foams as fast.
-
03
One stage of scavenging was added after concentration I to prevent concentration tailings from flowing into the iron products, so as to obtain sulfur concentrates. This process was rarely used before.
Equipment Innovation
