Dressing of scheelite and wolframite mixture ore 

The characteristic of scheelite and wolframite mixture ore is low grade and fine dissemination particle sizes. Black and white tungsten ore closely coexisting with a variety of useful minerals, gangue minerals’ composition are complex, so it usually requires complex processes for processing.

For scheelite and wolframite mixture ore, the key is fully recovered scheelite and wolframite mixture ore and comprehensive recovery of associated minerals.

At present, for scheelite and wolframite mixture ore sorting, using sulfide ore flotation and separation - scheelite and wolframite mixed flotation - coarse grain tungsten ore heating selection - wolframite slimes flotation processes, such as non-ferrous metals Shizhuyuan company; there is also processes based on gravity concentration, such as Fujian Xingluokeng tungsten mine.

 

Shizhuyuan Method

Metal mineral in Shizhuyuan contents various useful ores, of which the symbiotic relationship is very close and the ore composition is complex, so it belongs to refractory ore, mainly reflected in:

1. Ores contains sulfide ores and oxide ores with molybdenum, bismuth, iron, scheelite and wolframite mixture ore and fluorite;

2. Mineral dissemination particle sizes is uneven and smaller;

3. Grade of tungsten, molybdenum, bismuth, fluorite in ores is low, so it’s difficult to get a high recovery rate of qualified products;

4. Sulfide ores is associated with tungsten ores, symbiotic metasomatism alteration of scheelite and wolframite gets more serious;

5. Ores contains Ca-containing fluorite, calcite and garnet with similar floatability of scheelite, Ca-containing ores’ flotation separation is a worldwide problem.

 

Shizhuyuan metal mineral is a world class tungsten and molybdenum, bismuth large deposits with high comprehensive utilization of ore, having high economic value and strategic significance.
