Abstract
A compound chemical for floatation contains 1,3-dimethyl butyl xanthate, ethyl xanthate or/and isopropyl xanthate,and features lower cost and higher recovery rate. If said compound chemical is used to floatate the refractory ore, the recovery rate can be increased by 1-1.5% for Cu, 1% for Ag and over 5% for Au.
Description
The present invention relates to composite chemical for floatating, particularly the composite chemical for floatating of mainly forming by xanthate.
Since the positive impact that the cooperative effect between medicament produces floatation process, existing many composite chemical for floatating in the prior art.Chinese patent publication number CN1127164A discloses a kind of flotation agent of compound xanthate.It is by butyl xanthate, the amyl group xanthate, and the hexyl xanthate is formed, and further can increase the propyl group xanthate, is used to improve the noble metal rate of recovery.The composite chemical for floatating composition that this patent provides has three kinds of alkyl xanthate at least, and the carbon number of each xanthate is more than three.From the consumption of each xanthate, the propyl group xanthate consumption that carbon number is low is less relatively, and minimum is 7%.
It is low to the purpose of this invention is to provide a kind of cost, the composite chemical for floatating that the rate of recovery is high.
Composite chemical for floatating provided by the invention contains 1, a kind of in 3-dimethylbutyl xanthate and ethyl xanthate or the isopropyl xanthate.
Another program be composite chemical for floatating by 1,3-dimethylbutyl xanthate, ethyl xanthate and isopropyl xanthate are formed.
Composite chemical for floatating provided by the invention is formed simple, selects 1 of 6 carbon for use, and the xanthate of 3-dimethylbutyl xanthate and low carbon number is composite.1,3-dimethylbutyl xanthate has stronger selectivity, has good collecting simultaneously again.On the other hand, strengthened the consumption of rudimentary xanthate, consumption can reach 75%, has reduced the cost of composite drug.Especially can select ethyl xanthate for use, more reduce the cost of floating agent.Usually to be considered to selectivity the poorest for ethyl xanthate, and the present invention is by with ethyl xanthate and 1, and 3-dimethylbutyl xanthate composite under the lower cost condition reached good flotation effect.
Prepare above-mentioned composite chemical for floatating, only each component fully need be mixed getting final product.
In order to expand the range of application of composite chemical for floatating, on the basis of above-mentioned composite chemical for floatating, add amine alcohol xanthate again, butylamine black powder, ethyl ammonia sulfate or diethyldithiocarbamate.
Increase amine alcohol xanthate and be used for nonferrous metal sulfide mineral, mix the flotation of ore deposit and oxide ore and associated gold mineral, when grade is close, can improve gold recovery more than 5%, improve lead, zinc recovery is more than 3%; Increase the butylamine black powder and be used for the non-ferrous metal lead zinc sulphur ore, micro-oxide ore, associated gold, the flotation of silver ore when grade is close, can improve gold recovery more than 5%, can improve silver raising recovery rate 1-10%, improves lead, zinc recovery 3%; Increase the flotation that ethyl ammonia sulfate is used for the large-scale copper mine of non-ferrous metal (the porphyry type is done piece lithotype) mineral, and the flotation of associated gold mineral, when grade is close, improving copper recovery 1-2%, gold recovery is more than 5%; Increase the flotation that diethyldithiocarbamate is used for lead-zinc sulphide minerals, and the flotation of associated gold mineral, when grade is close, improving lead recovery 3-5% respectively, zinc recovery is more than 2%, and gold recovery is more than 5%.
Replace butyl xanthate with composite drug provided by the invention, handle refractory ore and can improve Cu rate of recovery 1-1.5%, improve the Au rate of recovery more than 5%, improve the Ag rate of recovery 1%.
Embodiment 1
The preparation composite chemical for floatating: with 1 part (weight, down with) 1,3-dimethylbutyl xanthate and 1 part of ethyl xanthate fully mix and get final product.
Replace butyl xanthate to handle the ore of Jiangxi Dexing Copper Mine the composite chemical for floatating of above-mentioned preparation, experimental result sees Table 1:
The relation of oxygenation efficiency and copper recovery during according to test index and processing refractory ore, as can be seen, use the rate of recovery that composite drug provided by the invention has improved copper and gold:
Handle refractory ore and can improve copper recovery 1-1.5%, improve gold recovery more than 5%; Handle free-milling ore and can improve copper recovery 0.5%, about, gold recovery improved more than 4%.
Do not carry out the screening of composite drug consumption in this test.See that from the situation of duration of test field observation to use the composite drug amount bigger than normal,, control the rough concentrate grade well, can eliminate the influence of composite drug concentrate grade as suitable reduction consumption.Embodiment 2
Prepare compound floating and make medicament: with 1 part 1,3-dimethylbutyl xanthate and 1 part of isopropyl xanthate fully mix and get final product.
Replace butyl xanthate to handle the copper mine ore composite chemical for floatating of above-mentioned preparation, select copper and associated gold, it the results are shown in Table 2: embodiment 3-6
The preparation composite chemical for floatating: in the composite drug of embodiment 1 preparation, add 2 parts of amine alcohol xanthate again, the butylamine black powder, a kind of in ethyl ammonia sulfate or the diethyldithiocarbamate fully mixes and gets final product.
Four kinds of composite chemical for floatating with above-mentioned preparation are tested respectively, and it the results are shown in Table 3-6.Embodiment 7
Preparation composite chemical for floatating: in the composite drug of embodiment 1 preparation, add 1 part of isopropyl xanthate again, fully mix and get final product.
Replace butyl xanthate to handle the copper mine ore composite chemical for floatating of above-mentioned preparation, select copper and associated gold, it the results are shown in Table 7.Table 1:
