Advances in technology of black tungsten ore beneficiation

China's black tungsten ore is mostly quartz vein type or fine vein type tungsten deposit, which belongs to gasification high temperature hydrothermal type deposit. The black tungsten ore is rich in plate or fine vein crystals enriched in quartz, and the inlay size is coarse. Easy to separate. This type of tungsten mine is large in scale and easy to sort, and has very important industrial value.

China's black tungsten ore beneficiation generally adopts the re-election-based joint beneficiation process, which is generally divided into the selection operation sections such as rough selection, re-election, selection and fine mud treatment. The principle of black tungsten ore dressing principle is shown in Figure 1. The principle process of black tungsten ore beneficiation is generally: pre-enrichment, hand-selection and waste; multi-stage jigging, multi-stage shaker, stage grinding, shaker tailing; fine mud returning to the team, various process selection, minerals Comprehensive recovery.

Note: Flower stone refers to a nugget containing black tungsten, the grade is between tungsten and waste rock.

Tungsten refers to a nugget containing more than 50% of a small amount of gangue minerals.
