Crystalline graphite is naturally floatable, so Xingaonai mainly uses flotation method to separate graphite ore. Flake graphite has good floatability, so flotation is mostly used for separation. For graphite ores with a variety of gangues, a combined gravity separation and flotation process can also be used.

The magnetite beneficiation method occupies a dominant position in iron ore separation. Xingaonai uses gravity separation, magnetic separation, flotation and roasting magnetic separation, as well as combined processes for weakly magnetic lean iron ore; for strong magnetic iron ore, it directly Processed by magnetic separation.

Stage grinding, stage separation, high separation efficiency; combined use of multiple processes, green and environmentally friendly; strong magnetic tailing-reverse flotation process to ensure concentrate grade.

According to the different properties of feldspar ore, xingaonai can design different feldspar beneficiation process plans, including magnetic separation, flotation or combined beneficiation process, etc., so as to remove iron, quartz, mica and other impurity minerals, and obtain potassium and sodium containing Feldspar concentrate, aiming to obtain high-grade feldspar concentrate.

The copper-lead-zinc mineral processing process adopts a mixed flotation-concentrate regrinding process, which can reduce grinding costs and is easy to manage. At the same time, new non-toxic flotation reagents are applied, which are efficient and environmentally friendly.
