Problems solved by technology

As we all know, xanthate has strong collection ability but low selectivity and no foaming performance; black medicine has weak collection ability but has strong selectivity and foaming performance
However, in the flotation of copper-nickel sulfide ore, nickel metal is mainly enriched in pyrite, and the ability of black powder to collect iron sulfide is weak, which makes the application effect of black powder unsatisfactory, resulting in xanthate and pyrite in production practice. The black drug mixed collector has strong collection capacity but poor selectivity, which is not conducive to the improvement of nickel concentrate grade and recovery rate, affects the technical indicators of ore dressing, and reduces the economic benefits of the dressing plant

Embodiment 1

[0009] The present embodiment is a general embodiment of the present invention, comprising the following steps: take the following raw materials by weight: concentration 99% isobutanol 28-40, phosphorus pentasulfide 17-35, concentration 20% ammonia 9-21, concentration 30 %hydroxamic acid 2-13 and concentration 95% ethylthiocarbamate 8-22; Its preparation method is: start water circulation vacuum pump, add weight meter concentration 99% isobutanol 28-40 in the reaction kettle, under stirring condition Add phosphorus pentasulfide 17-35, and heat the jacket with steam at the same time. When the temperature in the reactor rises to 70-80°C, react for 2 hours, then pass cooling water into the jacket, and wait until the temperature drops to 40°C , the medicine prepared in the reaction kettle is pumped into the metering tank to obtain supplies; take the supplies in the metering tank, add them to the ammoniation kettle, and stir while diluting with water. % ammonia water for ammoniatio...

Embodiment 2

[0011] The present embodiment is the best realization scheme of the present invention, comprising the following steps: taking the following raw materials by weight: concentration 99% isobutanol 36, phosphorus pentasulfide 28, concentration 20% ammonia water 15, concentration 30% hydroxamic acid 6 and a concentration of 95% ethylthiocarbamate 15, its preparation method is: start the water circulation vacuum pump, add 99% isobutanol 36 with a concentration of 99% by weight in the reactor, under stirring conditions, add phosphorus pentasulfide 28, and pass through the jacket simultaneously Steam heating, when the temperature in the reactor rises to 70-80°C, react for 2 hours, then pass cooling water into the jacket, and when the temperature drops to 40°C, pump the medicine prepared in the reactor to the metering tank In the process, get supplies; get the supplies in the metering tank, add in the ammoniation kettle, and stir while injecting water to dilute, when diluted to 70% conc...

Abstract

The invention relates to a copper-nickel sulphide ore floatation collector, which is prepared from isobutanol, phosphorus pentasulfide, ammonia water, hydroximic acid and ethionine ester. A preparation method comprises the following steps of: adding the isobutanol into a kettle, adding the phosphorus pentasulfide with stirring, introducing steam to heat to the temperature of the between 70 and 80 DEG C, performing reaction for 2 hours, injecting water into a jacket until the temperature is reduced to 40 DEG C, adding into an ammoniation kettle, injecting water for dilution with stirring, introducing the ammonia water for ammoniation when the concentration is diluted to 70 percent, controlling the ammoniation temperature to be 45 DEG C, and stopping introducing the ammonia water when the pH value reaches 8-9; continuously stirring for 20 minutes to obtain a substance for later use; weighing the substance for later use, the hydroximic acid and the ethionine ester based on weight part; and putting into the kettle sequentially, stirring at normal temperature for 1 hour, and discharging when the pH value is over 7 to obtain the finished product. The copper-nickel sulphide ore floatation collector has the advantages of strong selectivity and high recovery rate.

Description

technical field [0001] The invention relates to a sulfide mineral flotation collector, in particular to a copper-nickel sulfide ore flotation collector. Background technique [0002] At present, the flotation method of copper-nickel sulfide minerals at home and abroad is generally to use mixed collectors to strengthen the flotation of copper-nickel minerals in weak alkaline media, usually using the combination of xanthate and black powder, xanthate and esters Or high and low xanthate combination. Among them, the combination of tertiary xanthate and butylamine black is the most widely used as a mixed collector. The grade of nickel concentrate can generally reach 4-8%, and the recovery rate of nickel metal is between 70-85%. This method has been widely used. Used in industrial production. As we all know, xanthate has strong collection ability but low selectivity and no foaming performance; black medicine has weak collection ability but has strong selectivity and foaming perf...
