Abstract
The invention relates to a method for separating black and white tungsten bulk flotation rough concentrates. The method is characterized in that a black tungsten rough concentrate and a white tungsten rough concentrate are obtained by virtue of high-gradient magnetic separation, roughing or roughing and scavenging; black tungsten concentrates and black tungsten cleaner tailings are obtained via carrying out once roughing, three-time scavenging and four-time concentrating on the black tungsten rough concentrate by utilizing sodium fluosilicate, sodium silicate, aluminum sulfate, lead nitrate, benzohydroxamic acid and sulfated nascent soap; white tungsten concentrates and white tungsten cleaner tailings are obtained via carrying out once roughing, three-time scavenging and three-time concentrating on the white tungsten rough concentrate after the white tungsten rough concentrate is heated up and stirred by utilizing sulfated fatty acid soap, sodium silicate, caustic soda and sodium sulfide; cassiterites in the white tungsten cleaner tailings are recovered by a table concentrator. The method related by the invention has the advantages of small mutual interference of black tungsten ore and white tungsten ore in the black and white tungsten bulk flotation rough concentrates, high recovery ratio of black tungsten ore and high and stable quality of the black tungsten ore; and the method is suitable for the black and white tungsten bulk flotation rough concentrates containing 5-40% of WO3.
Description
Technical field
The present invention relates to a kind of separation method of tungsten ore, particularly a kind of black and white tungsten bulk flotation rough concentrate separation method.
Background technology
At present the method that more successfully scheelite and wolframite are reclaimed in flotation from complex multi-metal ores such as Containing Sulfur ore deposit, scheelite, wolframite, cassiterite, garnet, fluorite or calcite has GY method (Chinese patent 200410051961.1), CF method (Chinese patent 95117062.7) and persimmon bamboo plantation method (GY method and CF method comprehensively).Their common feature is to adopt chelating type collecting agent benzene first hydroximic acid or nitrosophenyl hydroxylamine amine salt, and bulk flotation of wolframite and scheelite in neutral ore pulp obtains to contain WO
3Be 5～40% black and white tungsten bulk flotation rough concentrate, it is 0.2～0.5% that this rough concentrate contains Sn, tungsten recovery rate 75～80%.These methods make the ore dressing of black and white tungsten mineral intergrowth that rapid progress arranged.Heat and stir flotation and also obtained good effect the white tungsten in this rough concentrate is selected.But, having added a large amount of waterglass, caustic soda and vulcanized sodium owing to heat to stir in the white tungsten refining process of flotation, wolframite is brought very big difficulty for the recovery wolframite by strong inhibition.Wolframite is difficult to activation by strong inhibition, and therefore, the black selected rate of recovery of tungsten and wolframite grade are all lower and unstable.
Summary of the invention
Mutual interference is little mutually with scheelite to the purpose of this invention is to provide in a kind of black and white tungsten bulk flotation rough concentrate wolframite, wolframite rate of recovery height, of high grade and stable separation method.
The step of black and white tungsten mixed crude concentrate separation method of the present invention is:
1) high-gradient magnetic separation: under background field intensity 0.5～1.0 tesla,, obtain black tungsten rough concentrate and white tungsten rough concentrate through one roughing or one roughing and once purging selection;
2) black tungsten is selected: black tungsten rough concentrate is dense to ore pulp weight concentration 30～45%, one roughing: add prodan 200g/t, waterglass 2000～3000g/t, aluminum sulfate 1000～3000g/t, plumbi nitras 400g/t, benzene first hydroximic acid 800～1200g/t, sulphation oleic acid soap 80～120g/t; Once purging selection: add benzene first hydroximic acid 300～500g/t, sulphation oleic acid soap 40～60g/t; Secondary is scanned: add benzene first hydroximic acid 60～200g/t, sulphation oleic acid soap 20～30g/t; Scan for three times: add benzene first hydroximic acid 40～100g/t, sulphation oleic acid soap 10～20g/t; Primary cleaning: add waterglass 600～1000g/t, aluminum sulfate 300～500g/t, benzene first hydroximic acid 200～300g/t; Recleaning: add waterglass 200～300g/t, aluminum sulfate 100～150g/t, benzene first hydroximic acid 100～200g/t; Triple cleaning: add waterglass 100g/t, aluminum sulfate 500g/t, benzene first hydroximic acid 200g/t; Four selected medicaments that do not add obtain wolframite and black tungsten cleaner tailings;
3) white tungsten is selected: white tungsten rough concentrate is dense to ore pulp weight concentration 50～70%, one roughing: add waterglass 40000～60000g/t, vulcanized sodium 2400～4400g/t, caustic soda 1200g/t, sulphation oleic acid soap 200g/t; Once purging selection: add sulphation oleic acid soap 100g/t; Secondary is scanned: add sulphation oleic acid soap 50g/t; Scan for three times: add sulphation oleic acid soap 50g/t; Triple cleaning does not all add medicament, obtains white tungsten fine ore and white tungsten cleaner tailings;
4) cassiterite is reclaimed in gravity treatment: white tungsten cleaner tailings reclaims the tin concentrate through gravity treatment, abandons gravity tailings.
Characteristics of the present invention are: 1. in the black and white tungsten bulk flotation rough concentrate, the magnetic contrast of wolframite and scheelite, adopting high-gradient magnetic separation that wolframite in the black and white tungsten bulk flotation rough concentrate is carried out magnetic separation with scheelite separates, wolframite and rider enter black tungsten rough concentrate, mineral such as scheelite, fluorite, calcite and cassiterite enter white tungsten rough concentrate, selected respectively, do not disturb mutually; 2. the floatability when having kept bulk flotation owing to wolframite, easily-activated, easily reclaim, and calcium minerals such as calcite, fluorite are few in the black tungsten rough concentrate, can obtain the wolframite of high-grade, high-recovery when selected; 3. cassiterite is enriched in the white tungsten cleaner tailings, and available gravity treatment is reclaimed.The wolframite that separation method of the present invention obtains contains WO
340～67%; White tungsten fine ore contains WO
3Greater than 65%, the selected WO of black and white tungsten bulk flotation rough concentrate
3Overall recovery greater than 96%.
