Chromite sand is getting through washing,drying, desiliconizing,sieving from Chrome ore of south africa.

Zhengzhou haixu abrasives co.,ltd,has founded productions lines of chromite sand in Lianyungang from 2016,until now totally have 5 production lines (2 at Lianyungang port and 3 at Tianjin Port).There are 4 production lines only produce foundry grade chromite sand and one at lianyungang mainly produce chromite powder/flour.
