Problems solved by technology

At present, the Petroff method, that is, the concentrated slurry high-temperature method, is widely used. Its beneficiation index is relatively stable and it has strong adaptability to ore, but it needs to heat the ore pulp, and the beneficiation cost is high.

Embodiment Construction

[0033] A beneficiation agent for separating scheelite from complex tungsten ores, the beneficiation agent includes oxidized paraffin wax soap 8, kerosene 1, butyl xanthate 2, butylammonium black medicine 3 as collectors, and sodium carbonate 5 as regulator , using terpineol oil 4 as a foaming agent, and using a combination of sodium silicate 6 and ferrous sulfate 7 or aluminum sulfate 9 as an inhibitor.

[0034] The mineral processing agent for separating scheelite from complex tungsten ores, the mineral processing agent is to add 470-1350 grams of oxidized paraffin soap 8, 30-150 grams of kerosene 1, and 150-550 grams of butyl xanthate per ton of raw ore 2. Add 30-150 grams of butyl ammonium black medicine 3. Add 2000-4500 grams of sodium carbonate 5. Add 10-60 grams of pinitol oil 4. Add 3050-7000 grams of sodium silicate 6 and add 400-1300 grams of ferrous sulfate 7 or add 65 to 160 grams of aluminum sulfate 9.

[0035] Such as figure 1 As shown, a method for separating s...

Abstract

The invention relates to a beneficiation reagent and a method for separating scheelite from complex tungsten ore; the beneficiation reagent adopts oxidized paraffin soap, kerosene, butyl xanthate, dithiophosphate BA as collectors, adopts sodium carbonate as modifier and terpenic oil as foaming agent, and also adopts one or the combination of Sodium silicate and ferrous sulfate or aluminum sulfate as inhibitor; the method employing the beneficiation reagent for separating scheelite from complex tungsten ore includes: desliming in normal temperature, carbon-sulfide bulk rough floatation, secondary tungsten rough floatation and quintic tungsten concentration, so tailings and tungsten concentrate product are obtained; besides, the invention has the advantages of high sorting efficiency, high yield rate, wide reagent resource, low price, low cost and dosage, simple and reliable process, easy operation and normal temperature working, and is particularly applicable to the beneficiation application of complex tungsten ores.

Description

1. Technical field [0001] The invention relates to a beneficiation agent and method for separating scheelite from complex tungsten ores, and is particularly suitable for the beneficiation application of complex tungsten ores. 2. Background technology [0002] Complex tungsten ores generally refer to ores containing pyrite, stibnite, ferro-titanium oxide particles, quartz, calcite, sericite, argillaceous matter, aphanitic carbon, and the like. The separation of aphanitic carbon, calcite and scheelite from complex tungsten ores has always been recognized as one of the difficult problems in mineral processing, and it is also the main reason why such tungsten ores are difficult to utilize. The reasons: First, there are calcium-containing minerals similar to scheelite in floatability, such as calcite, fluorite and apatite, which complicate the planktonic process. The flotation separation of scheelite and calcium-containing minerals is An important factor affecting the separation...
