Ore Beneficiation

Due to the depleting reserves of DSO ores and increasing development of low-grade hematite and magnetite deposits, the need for iron ore beneficiation is increasing. Even the DSO ores are requiring a higher level of processing as the depth of existing mines is increasing (below water table) where ores are wet and more sticky, which creates challenges for conventional crushing and screening.

We can dispose of strong magnetic minerals and iron scraps through low-intensity magnetic separation. Then we dry the ores and divide them into three grades, namely +0.2, +0.1 and -0.1mm. After roughing separation and scavenging process through the dry high-intensity magnetic separator, we will get tantalum-niobium ore concentrate. Get price
