- How Is Tungsten Ore Crushed
The mineral treatment process for the Sangdong ore involves primary, secondary and tertiary crushing, two-stage grinding, flotation, thickening and filtration for the production of final tungsten concentrate at a rate of 5,519tpa. The crushed ore will be ground in a 3.3m-diameter and 4.9m-long rod mill which discharges to a cyclone cluster.

Once extracted, the ore is crushed and undergoes beneficiation to separate tungsten from waste, using methods like gravity separation and flotation. The concentrate is then roasted to remove impurities and convert tungsten minerals into tungsten oxide (WO3), which is reduced to produce pure tungsten metal for various uses. Common Tungsten Forms

In this mine, tungsten ore is crushed to a coarse average size of 2.25 mm to liberate the tungsten minerals from the gangue. The higher friability of wolframite compared to the rest of the gangue minerals in the ore means that wolframite tends to end up disseminated in fine particle form, leading to a fines feed with almost double the …

The ore will be crushed in two stages, stored in a fine ore stockpile, followed by crushing in a fine vertical shaft impact crusher. The crushed ore will be passed through the gravity circuit and the resultant tailings forwarded to the flotation circuit for processing. The produced concentrate will be sold in the Ammonium Paratungstate market.
