Embodiment 1

[0040] Utilize the mineral flotation collector of the present invention to process scheelite ore in a certain place in Henan, its technological process is as follows figure 1 Shown (the mixed collector in the figure is the mineral flotation collector of the present invention), wherein the tungsten grade WO 3 The gangue is mainly feldspar, diopside, quartz and a small amount of calcite, fluorite and square pillar.

[0041] Combine calcium chloride: salicylic hydroxamic acid: linoleic acid = 0.7:1.5:0.2 according to the mass ratio and put it into a 250mL three-neck flask, add water to form a solution with a mass fraction of 10%, then start the magnetic stirrer and stir The speed is 600r / min, the constant temperature of the water bath is 60°C, and the prepared mineral flotation collector is taken out after stirring for 20 minutes.

[0042] Grind the scheelite ore to -0.074mm, accounting for 70%-76% fineness, put it into the flotation tank and stir for 1min, adjust the pH of the ...

Embodiment 2

[0047] Utilize the mineral flotation collector of the present invention to process tungsten-tin raw ore in a certain place in Hunan, and its technological process is as follows figure 1 Shown, where tungsten grade WO 3 0.40% (70% of scheelite and 30% wolframite), Sn grade of 0.17%, gangue mainly garnet, fluorite, quartz, mica, calcite and a small amount of montmorillonite and chlorite Wait.

[0048] According to the mass ratio, lead nitrate: benzohydroxamic acid: oxidized paraffin wax soap = 1:1:0.1 is combined and put into a 250mL three-necked flask, water is added to form a solution with a mass fraction of 7%, and then the magnetic stirrer is started. The stirring speed is 700r / min, the constant temperature of the water bath is 70°C, and the prepared mineral flotation collector is taken out after stirring for 15 minutes.

[0049] Grind the raw tungsten-tin ore to -0.074mm, accounting for 75%-80% fineness, put it into the flotation tank and stir for 1min, adjust the pH of t...

Embodiment 3

[0054] Utilize the mineral flotation collector of the present invention to process tin ore in a certain place in Guangxi, its technological process is as follows figure 1 As shown, the tin grade Sn in the tailings after sulfur selection is 0.52%, and the gangue is mainly quartz, calcite, and a small amount of mica and dolomite.

[0055] Combining manganese sulfate: N-oleoyl sarcosine: sodium dodecylsulfonate = 0.5:1.5:0.5 according to the mass ratio, put it into a 250mL three-necked flask, add water to form a solution with a mass fraction of 15%, Then start the magnetic stirrer, the stirring speed is 500r / min, the constant temperature of the water bath is 60°C, and take out the prepared mineral flotation collector after stirring for 25min.

Abstract

The invention discloses a mineral flotation collector as well as a preparation method and application thereof. The mineral flotation collector contains soluble metal salt, a chelating type medicamentand fatty acid or a derivative thereof, wherein the mass ratio of the soluble metal salt to the chelating type medicament to the fatty acid or the derivative thereof is (0.5 to 1) to (1 to 3) to (0.05to 0.5). According to the mineral flotation collector, metal coordination ions in the soluble metal salt, a chelating agent and a fatty acid type collector are pre-assembled according to a specific ratio to obtain a multi-ligand collector with high selectivity and collection capability, and a traditional thinking that sediment is generated when the soluble metal salt, the chelating type medicament and a fatty acid type medicament are mixed and the acting effect of the medicament is reduced is broken through; and the difficulty that tungsten ore and cassiterite are not easily separated from gangue minerals, especially calcium-containing gangue minerals, is solved.

Description

technical field [0001] The invention relates to the technical field of mineral flotation, in particular to a mineral flotation collector and its preparation method and application. Background technique [0002] Tungsten and tin are commonly used metals in daily production and life, especially tungsten is a strategic rare metal, which is widely used in aerospace, machinery industry and smelting chemical industry because of its high melting point, high hardness, corrosion resistance and other advantages field. Tin is a silver-white metal with low melting point, good plasticity, corrosion resistance and non-toxicity. Therefore, tin is also widely used in various fields of national economy and national defense construction, such as tin-titanium alloy, niobium-tin alloy and emulsifier in ceramic industry. [0003] Among the mineable tungsten resources in the world, scheelite is the main one, accounting for about 70%, while wolframite accounts for about 20%. Due to its large sp...
