Tungsten Jigging Machine Mining Beneficiation Equipment For Separation Of Scheelite And Wolframite - China

The beneficiation method for wolframite tungsten is gravity separation

because density of wolframite tungsten is big, and gravity separation

can easily remove the other materials whose density is below 3.5-4,

especially for the quartz vein wolframite tungsten.

This gravity

separation is much more suitable for the coarse tungsten because

wolframite tungsten is of large crystals.

Jiggers and shaking tables are the plants commonly used in wolframite tungsten gravity separation for the coarse & medium embedded tungsten.

Screening & classifying is needed before jigging beneficiation.

Jigger is usually put into the milling phrase to reduce the pelitization of the tungsten and to recover the liberated tungsten.

The tungsten concentrate enriched by jigger accounts over 45% of all concentrate recovered,

Shaking table is mainly used for the ore below 1mm with its high enrichment rate.

Strict classifying is necessary before the beneficiation to gain good separation efficiency.

Water classifier is used to classify in the beneficiation factories.

Scheelite tungsten ore beneficiation

Scheelite tungsten ore is concentrated by gravity separation combined with floatation separation or only floatation separation according to the ore dip-drying characteristics while some scheelite tungsten ore needs pre-beneficiation like the beneficiation factory in King Island, Australia.

There Uv fluorescent is adopted to remove the 50% of waste stones, and the grade will be lower than the tailings discharged from the beneficiation factory with the tungsten recovery is 90-96% &the treatment capacity is 30-40t/h.

The sulfide ore is usually mixed in the white ore bed with the molybdenite especially common.

During the beneficiation, sulfide ore will be beneficiated by floatation separation, and then the Scheelite will be floated then.

The floatation of Scheelite is done in alkaline medium.

Na2CO3 and NaOH will be used to improve the Ph of the pulp to 9-10.5 - Sodium silicate, quebracho juice, tannin, kinds of phosphate will work as inhibitor.

oleic acid, sodium oleate, tall oil, oxidized paraffin wax soap will be used as collector with its own frothing capacity while most of them needs no blowing agent when working.

Scheelite ore has great floatable ability.

It is usually is included in the calciam-bearing ores like calcite, fluorite, phosphorite, which makes the floatation separation sophisticated.

Multi-chemical-valence metal salts like FeSO4 will be added to sodium silicate to improve the floatation efficiency of Scheelite.

To improving the pulp temperature is another way to improve the floatation efficiency.

Petrov method is to absorb the collector on the calcite to float the white tungsten by making the pulp temperature up to 70-90 degrees and adding large quantity of sodium silicate.

There are not too many white tungsten beneficiation factories in China to occupy 5% of the tungsten beneficiation.

The white tungsten beneficiation factory in Baoshan, Dangping, used oleic acid as collector and refined by Pstrov method and latter, the collector has been changed to oxidized paraffin wax soap of 731 which is vice-product of petrolium industry with its large resource & low price.

Additionally, the pulp needs no heating and the floatation efficiency will be great in normal circomstance.
