| Abstract: |
| This paper introduces some results of investigation on mineral processing technology of a iron-zinc mine in Hebei Province.Most of zinc minerals in the deposit are coarse grain,others are finely disseminated and closely associated with iron minerals,which need to be finely ground in order to get well-liberated minerals.After a comprehensive comparison between flotation-magnetic separation flowsheet and magnetic separation-flotation flowsheet,a very good separation performance has been achieved by means of employing a multi-stage grinding and separation technology followed by flotation-magnetic separation.The technology flowsheet has been adopted to build a mineral processing plant in Hebei Province. |
