Abstract
The present invention relates to a separation method of Cu and Sn mixed filings. A treated agent solution and mixed filings are thoroughly mixed. Water is used as a medium for separating hydrophobic bronze filings from hydrophilic tin alloy filings, and the separation can be carried out on a shaking table. A separation method of the present invention can obtain two kinds of alloy filings which maintain original constituents. The hydrophobic bronze filings contain 82.27 to 85.53% of Cu and the hydrophilic tin alloy filings contain 81.33 to 82.55% of Sn. the yield of two qualified products is from 96.9 to 95.8%. The present invention has the advantages of easy enforcement, less equipment investment, low production cost and large economic benefits; the separation method of Cu and Sn mixed filings is especially suitable for the separation of the processing filings of bearing shells.
Description
The present invention relates to the desk-top method for floating at acid bronze alloy that a kind of separation mixes and kamash alloy bits end, particularly bronze and ashbury metal bits end.
The a large amount of bronze, the ashbury metal mixed filings that produce in the cu bearing liner process of departments such as locomotive, boats and ships, machine-building also do not have a kind of easy, effective separation method so far, are taken as waste disposal usually.It is to utilize the difference of two kinds of alloy melting points (bronze is about 967 ℃ that a kind of method is arranged, ashbury metal is about 370 ℃) the temperature control fusing, but because of the ashbury metal of fusion is difficult to remove fully from the surface at bronze end, separate can not get satisfied effect, separation rate is 20-30% only.With can not be maintained two kinds of alloys of original component of pyrogenic process or hydrometallurgy, can only be molten into certain rudimentary alloy or extract certain metal and utilize, and complex technical process, cost height, with waste gas or contaminated wastewater.
The purpose of this invention is to provide a kind of more simple and do not destroy two kinds of original components of alloy mix metal fillings separation method not.
Solution of the present invention is to use the 400-2000g/T(metal fillings) butyl dithiocarbonic acids sodium, 140-300g/T(metal fillings) neutral oil be that inorganic agent and water are mixed with the inorganic agent solution that concentration is 0.5-2g/L; With inorganic agent solution with mix metal fillings end and fully mix; Water is that separating medium separates hydrophobic bronze bits end with hydrophilic ashbury metal bits end.
Treated dose acted on mix the metal fillings end, ashbury metal bits end wherein is still hydrophilic, and that bronze bits end is subject to processing the effect of agent is hydrophobic, can swim in when being exposed out the water surface on the water surface, thereby separate with ashbury metal bits end.Separation can be carried out on shaking table, and the process conditions of shaking table are: 5-6 ° of the bed surface gradient, stroke 10-12mm, jig frequency 320-340 time/minute, feed water yield 320-480 ml/min, washing water quantity 2000-4800 ml/min.When considering the particle size range broad at end to be worth doing, do suitable classification earlier, when handling the coarse fraction material, dosage, the feed water yield, flushing water are measured high value, the fine-graded low value of then getting.
Separation method technological process of the present invention is simple, implement easily, easy and simple to handle, equipment investment is few, production cost is low, product quality and productive rate height, economic benefit are big.
Embodiment 1. mixes in the metal fillings end, and 6-6-3 bronze end, 11-6 ashbury metal end, iron end three's weight ratio is about 57: 38: 5, uses the magnetic force deironing, and classification.
Wherein the inorganic agent proportioning to the 3-5mm metal fillings is: butyl dithiocarbonic acids sodium 2000g/T(metal fillings), pumping fluid 300g/T(metal fillings), inorganic agent solution concentration 2g/L; To mix the metal fillings end with after soaking into 1 minute under processing agent solution infiltration 60 minutes or the gentle agitation, separate with shaking table, condition of work is: 6 ° of the bed surface gradients, stroke 12mm, jig frequency 320 times/minute, the feed water yield 480 ml/min, washing water quantity 4800 ml/min.Isolated ashbury metal end contains Sn82.55%(weight), bronze end contains Cu85.53%(weight).Two kinds of qualified products productive rates are all 92.1%.
Wherein the inorganic agent proportioning to the 1-3mm metal fillings is: butyl dithiocarbonic acids sodium 700g/T(metal fillings), gasoline 200g/T(metal fillings), inorganic agent solution concentration 1g/L; To mix the metal fillings end with after soaking into 1 minute under inorganic agent infiltration 60 minutes or the gentle agitation, and separate with shaking table, condition of work is: 6 ° of the bed surface gradients, stroke 10mm, jig frequency 340 times/minute, the feed water yield 400 ml/min, washing water quantity 4000 ml/min.Isolated ashbury metal end contains Sn82.40%(weight), bronze end contains Cu84.46%(weight).Two qualified products productive rates are 95.8%.
Wherein be to inorganic agent proportioning less than the 1mm metal fillings: butyl dithiocarbonic acids sodium 400g/T(metal fillings), gasoline 140g/T(metal fillings), inorganic agent solution concentration 0.5g/L; To mix the metal fillings end with after soaking into 1 minute under inorganic agent infiltration 60 minutes or the gentle agitation, and separate with shaking table, condition of work is: 5 ° of the bed surface gradients, stroke 10mm, jig frequency 340 times/minute, the feed water yield 300 ml/min, washing water quantity 2000 ml/min.Isolated ashbury metal end contains Sn81.33%(weight), bronze end contains Cu82.27%(weight).Two qualified products productive rates are 86.9%.
More than each grade product reach the quality standard of 6-6-3 bronze and 11-6 ashbury metal respectively.
Embodiment 2. mixes in the metal fillings end, and 10-1 bronze end, 4-4 ashbury metal end, iron end weight ratio are about 56: 38: 6, and use the magnetic force deironing, and be divided into three grades: 3-5mm, 1-3mm is less than 1mm.Adopt the same method of embodiment 1, separate obtaining 10-1 bronze end and contain Cu86.7-89.5%(weight), the 4-4 ashbury metal contains Sn90.1-91.0%(weight), two qualified products, its productive rate 80.8-90.2%.
