Embodiment 1

[0050] Preparation of collector:

[0051]Add 200 parts of X oil and 153.3 parts of diesel oil into the reactor, and add 30 parts of phosphorus pentasulfide, and stir and react at 120°C for 2 hours to obtain a black oily liquid, which is the target collector product. After analysis and detection, the conversion rate of phosphorus pentasulfide is close to 100%, and the content of dihydrocarbyl dithiophosphoric acid in the collector product is 10.4%. The product was characterized after being separated and purified by silica gel chromatography, and the infrared spectrum of dicyclohexyl dithiophosphoric acid was as follows: figure 1 As shown, its main characteristic peaks are (cm -1 ): 2932, 2856 belongs to CH 2 The stretching vibration peak, 2662, 1450 is assigned to CH 2 Absorption peak; 1364 belongs to CH absorption peak; 1067 belongs to P-O-C, 968 belongs to P-O-CH 2 Absorption peak; 839 belongs to S-H absorption peak; 789,672 belongs to P=S absorption peak. dicyclohexyl d...

Embodiment 2

[0053] Preparation of collector:

[0054] Add 200 parts of X oil and 146.7 parts of diesel oil into the reactor, and add 20 parts of phosphorus pentasulfide, and stir and react at 110°C for 2 hours to obtain a black oily liquid, which is the target collector product. After analysis and detection, the conversion rate of phosphorus pentasulfide is close to 100%, and the content of dihydrocarbyl dithiophosphoric acid in the collector product is 7.2%.

Embodiment 3

[0056] Preparation of collector:

[0057] Add 200 parts of X oil and 90.2 parts of diesel oil into the reactor, and add 10.5 parts of phosphorus pentasulfide, and stir and react at 100°C for 2 hours to obtain a black oily liquid, which is the target collector product. After analysis and detection, the conversion rate of phosphorus pentasulfide is close to 100%, and the content of dihydrocarbyl dithiophosphoric acid in the collector product is 4.6%.

Abstract

The invention discloses a sulfide ore floatation composite collecting agent and a preparation method and application thereof. The sulfide ore floatation composite collecting agent is composed of modified X oil and hydrocarbon-type oil. The preparation method of the sulfide ore floatation composite collecting agent comprises the steps that the hydrocarbon-type oil is used as a solvent; and the X oil and phosphorus pentasulfide react, and thus the composite collecting agent composed of the modified X oil and the hydrocarbon-type oil is obtained. The preparation method is wide in raw material source, low in cost and simple in process operation, the prepared floatation collecting agent has high collecting capacity and selectivity to sulfide ores such as copper sulfide ores, copper-molybdenum ores and lead-zinc ores are achieved, and good floatation indexes in a floatation test are obtained.

Description

technical field [0001] The invention relates to a sulfide ore flotation composite collector, in particular to a sulfide ore flotation composite collector prepared by using cyclohexane oxidation by-products, especially suitable for copper sulfide ore, copper-molybdenum ore, lead-zinc ore The invention relates to the flotation of sulfide minerals, belonging to the technical field of mineral flotation. Background technique [0002] In the industrial process of preparing cyclohexanone and cyclohexanol by oxidation of cyclohexane, the by-product heavy component waste oil is called X oil, and its discharge accounts for about 5% to 8% of the output of cyclohexanone. The appearance of X-oil is a brown-black viscous liquid. Its composition is very complex, and the content of single components is low. It is very difficult to use. At present, it is mainly burned as fuel, causing serious environmental pollution. In recent years, some recycling technologies of X oil have been developed ...
