Tungsten ore dressing is pre-dominant, re-election, flotation and magnetic
separation methods such as physical beneficiation; difficult to select for
low-grade ore and ore concentrates using chemical methods. Tungsten Ore mineral
optional features according to the re-election into wolframite mineral-based
processes and the main scheelite flotation beneficiation process.
Wolframite
wolframite ore beneficiation process mining dilution has a high rate of low
grade minerals embedded in coarse particle size distribution, density, hardness,
small, easy to clay, color depth, etc., mineral-based approach to re-election.
The process includes pre-selected, graded re-election, selection of fine mud
with comprehensive recovery and processing of four parts.
For pre-washing
before, off the mud with grading, pre-hand-election, election and optical
methods such as heavy media beneficiation. The amount of pre-ore accounted for
50% of discarded waste rock, waste rock in the WO3 grade of 0.012% ~ 0.016%. Ore
grade of the pre-WO3 0.3% from 0.25% to 0.45% enrichment of 0.8%, recovery 96%
to 98%. After pre-crushing of ore grading to re-election-12mm, coarse grade ore
using triple elimination, elected to two-jig jig-based fighting diaphragm.
Large-scale concentrator using 1000mm × 1000mm (MeXaHoБp) Jig, China tungsten
processing plant down the 600mm × 900mm self-made side-action diaphragm jig.
Shaker re-election in four to six for. Need to re-elect a shaker or two before
grinding, there is also another mill in the ore grinding process. Using a
grinding rod mill, ball mill or the use of Sec grinding rod mill. Sorting using
the elbow roll shaker plate and convex, some of China’s tungsten processing
plant with spring-type shaker. Re-elect more than 90% average recovery
operations. Large and medium-sized selection of tungsten processing plant and
associated metals are integrated recovery process. Small tungsten ore processing
plant to a special selection of crude plant selection and comprehensive
recovery.
Selection were used to re-election, Taiwan, floating, flotation,
magnetic separation, electrostatic separation, chemical processing and so on.
Selected recovery of 95% to 98%. Shaker is used to further improve the selection
of tungsten grade, integrated platform floating recovery associated with sulfide
ore flotation, magnetic separation and electrostatic separation wolframite,
cassiterite, niobium and tantalum ore, etc. Chemical processing used to process
refractory ore with low grade tungsten concentrate in the production of
synthetic scheelite and APT. Comprehensive recovery can be obtained from the
tungsten-tin ore, molybdenum, copper, lead, zinc, bismuth, sulfur, gold, silver,
antimony, beryllium, lithium, potassium, arsenic, metals, scattered elements,
crystal and other 20 kinds of products. Most of China’s tungsten ore dressing
plant utilization of associated elements are still some potential.
With its high quality products such as 、、、Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
