OREANDA-NEWS. April 19, 2011. The Trial Run Ceremony of the 2nd Phase Sijiaying Concentration Plant (with an annual output of 15 million tons) was formally convened in Hebei. Up to now all the workshop equipment of the plant has been running smoothly, which marks that the largest domestic concentration plant designed by MCC Northern Engineering & Technology Corporation (NETC) has been proved to be a success in terms of the trail run, reported the press-centre of MCC.

This works is featured by complicated nature of the ore. In this regard, NETC adopted advanced technical processes in the design, for instance: staged grinding; coarse/fine classification; gravity separation, magnetic separation and reverse anionic flotation. Both the concentration process and equipment are rated to be come up to the international advanced standard.

For instance, the high-pressure roller mill utilized for fine crushing device will not only reduce the energy consumption, but also increase the grinding efficiency.
