of each valuable component is extremely low, far below the
industrial grade that can be economically utilized. Among
them, the mFe content is about 5%, while Cu and P2O5
contents are approximately 0.04% and 2%, respectively. It
is technically difficult for comprehensive recovery to taking
into account both economy and efficiency.
This paper proposes the concept of performing the
main separation process under rough grinding conditions
and reducing the feed quantity by multistage pre concen-
tration. This will allow for a high efficiency comprehensive
recovery flowsheet that is flexible and that can fully utilize
the properties of the ore. The industrial test results demon-
strate that an iron concentrate with a TFe grade of 65.23%
and an TFe recovery of 46.82%. The resulting phosphate
concentrate boasts a P2O5 grade of 33.10% and a recovery
of 63.04%. Additionally, the copper concentrate exhibits
a Cu grade of 16.12% with a recovery of 41.46%. These
outcomes indicate successful simultaneous recovery of iron,
phosphorus, and copper, showcasing favorable technical
and economic performance. The insights gleaned from this
study provide valuable guidance for similar mines aiming
to optimize their recovery processes.
