Abstract
The invention relates to application of methylne bis (bitutyl dithio carbamate) in flotation of copper-molybdenum ore and is characterized in that a use method is as follows: smashing and levigating sulfide ore containing copper and/or molybdenum; adding water until the solid content in ore slurry reaches 30-35%; adding 300-500 g/ton raw ore of activating agent sodium sulfide, 1000-1800g/ton raw ore of inhibitor sodium silicate and 10-20g/ton raw ore of collector methylne bis (bitutyl dithio carbamate); and carrying out primary roughing, three times of scavenging and three times of selections, and obtaining copper concentrate. Compared with the existing collector, the collector methylne bis (bitutyl dithio carbamate) provided by the invention does not block a pipeline, is convenient for operation, is used for achieving the flotation of copper-molybdenum sulfide ore in an alkaline medium, and is strong in adaptability; use amount of the collector is less, and production cost is low, so the collector methylne bis (bitutyl dithio carbamate) is beneficial to popularization and application in a dressing plant; and the metal recovery rate of the copper-molybdenum sulfide ore in the process of copper-molybdenum sulfide ore flotation is improved by using the collector in the invention.
Description
Technical field
The present invention relates to the application of di-2-ethylhexylphosphine oxide (dibutyl dithiocaarbamate ester) as copper-molybdenum flotation selective copper collector.
Background technology
With dibutylamine, carbon disulfide, carrene is the synthetic di-2-ethylhexylphosphine oxide (dibutyl dithiocaarbamate ester) of raw material, and chemical formula is ((C

2, structural formula is:
Outward appearance is amber transparency liquid, and trade name has Octopol MB Vanlube 7723 etc., is a kind of Ashless type antioxidant, extreme pressure anti-wear additives.Are used widely in senior anti-oxidant, wear-resisting lubricant and fields such as organic chemical industry, macromolecular material additive in automobile and engineering machinery.As antioxidant, general consumption is 0.5～1.0%; As extreme pressure anti-wear additives, addition is 2.0～4.0%.Also can be used for the occasion such as crank lubricating, engine oil, gear oil, various lubricating grease, metal working fluid under the high temperature.
At present, roughly be divided into three major types with the collecting agent of flotation and recovery of copper molybdenum ore: 1. xanthate class collecting agent, as butyl xanthate, ethyl xanthate, the compound xanthate of methyl isopentyl, Isobutylxanthic acid etc.; 2. black powder class collecting agent is as aniline black powder, dibutyl Sodium Aerofloat etc.; 3. ester class collecting agent, as xanthic acid Ethyl formate, ethoxy carbonyl thiocarbamate, curing phosphate, N-pi-allyl O-isobutyl group thionic carbamate, methyl thiourethane etc.The xanthate that wide material sources, valency are scrupulously and respectfully cheap is the sulfide mineral collector that uses the earliest, but it also is a poor selectivity, the sulfide mineral collector that performance is least stable.Shortcoming is to require to use under the highly basic condition and easily oxidation, and therefore the research of black powder collecting agent just arranged.Because the black powder collector dosage is big, lack pyritous selectivity collecting, just caused the research of ester class collecting agent.Ester class collecting agent is not quite water-soluble usually, is added in the grinding machine with raw form or with the form of emulsion, and requiring the pH scope is 4～9.Ester class collecting agent is the extraordinary selective copper collector of copper mineral and the flotation of molybdenum ore thing.Because ester class collecting agent also has the collecting performance to pyrite, under the situation that pyrite exists, copper mineral and molybdenum ore thing floatation indicators are under some influence, and production cost is higher, influences its application.Because di-2-ethylhexylphosphine oxide (dibutyl dithiocaarbamate ester) has good affinity with copper, molybdenum, this provides possibility for di-2-ethylhexylphosphine oxide (dibutyl dithiocaarbamate ester) is applied in the ore dressing flotation as collecting agent.
Summary of the invention
The objective of the invention is to propose the purposes of a kind of described di-2-ethylhexylphosphine oxide (dibutyl dithiocaarbamate ester) in the flotation and recovery of copper molybdenum ore.
The application of di-2-ethylhexylphosphine oxide of the present invention (dibutyl dithiocaarbamate ester) in the copper-molybdenum flotation, its using method is as follows: with the sulfide ore pulverizing and jevigating of cupric and/or molybdenum, add water to ore pulp and contain solid weight 30～35%, add activator vulcanized sodium 300～500 gram/ton raw ores, inhibitor waterglass 1000～1800 gram/ton raw ores, and interpolation di-2-ethylhexylphosphine oxide (dibutyl dithiocaarbamate ester) collecting agent 10～20 gram/ton raw ores, through one roughing, scan and triple cleaning for three times, obtain copper concentrate.
Under the situation of raw ore cupric 0.76～1.5%, copper oxygenation efficiency 7～15%, obtain copper concentrate and contain Cu20～25%, rate of recovery Cu 80～85%.Contain at raw ore under the situation of molybdenum 0.1～0.2%, through one roughing, scan and triple cleaning, obtain to contain the molybdenum concntrate of molybdenum 50～52%, the rate of recovery 89～92% for three times.Contain at raw ore under the situation of molybdenum 0.1～0.2%, through one roughing, scan and triple cleaning, obtain to contain the molybdenum concntrate of molybdenum 53～55%, the rate of recovery 89～92% for three times.
The mineral processing index contrast of the present invention and existing collecting agent sees Table 1.
Compared following characteristics with existing collecting agent: 1. this not plugging of collecting agent road, easy to operate; 2. realize copper, molybdenum sulfide flotation in alkaline medium, adaptability is strong.Consumption is few, and production cost is low, helps promoting the use of in the ore dressing plant; 3. adopt collecting agent of the present invention, the metal recovery rate of copper, molybdenum sulphide ore improves when Floatation of Copper, molybdenum sulphide ore.
The mineral processing index contrast of table 1 the present invention and existing collecting agent
