Abstract
A kind of separation method of Cu and Sn mixed filings fully mixes inorganic agent solution with mixed filings, and water is that medium separates hydrophobic bronze bits end with hydrophilic ashbury metal bits end.Separation can be carried out on shaking table.Separation method of the present invention can obtain to keep two kinds of alloy bits ends of original component; The bronze end contains Cu82.27-85.53%, and ashbury metal contains the productive rate 96.9-95.8% of Sn81.33-82.55%, two qualified product.Implement easily, equipment investment is few, production cost is low, economic benefit is big, is specially adapted to the separation at bearing shell processing bits end.
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 the mixed filings separation method of two kinds of original components of alloy.
Solution of the present invention is that the alkyl dithiocarbonic acids sodium with 400-2000g/T, neutral oil and the water of 140-300g/T are mixed with the inorganic agent solution that concentration is 0.5-2g/L; Inorganic agent solution is fully mixed with mixed filings; Water is that separating medium separates hydrophobic bronze bits end with hydrophilic ashbury metal bits end.
Treated dose of mixed filings that acted on, wherein ashbury metal bits end 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.
6-6-3 bronze end, 11-6 ashbury metal end, iron end weight ratio are about 57: 38: 5 in embodiment 1. mixed filings, use the magnetic force deironing, and classification.
Wherein the inorganic agent proportioning of 3-5mm is: butyl dithiocarbonic acids sodium 2000g/T, pumping fluid 300g/T, solution concentration 2g/L; Mixed filings with after soaking into 1 minute under processing agent solution infiltration 60 minutes or the gentle agitation, is separated with shaking table, and 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 Sn 82.55%, bronze end contains Cu 85.53%.Two qualified products productive rates are 92.1%.
Wherein the inorganic agent proportioning of 1-3mm is: butyl dithiocarbonic acids sodium 700g/T, gasoline 200g/T, solution concentration 1g/L; Mixed filings with after soaking into 1 minute under inorganic agent infiltration 60 minutes or the gentle agitation, is separated with shaking table, and 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 Sn 82.40%, bronze end contains Cu 84.46%.Two qualified products productive rates are 95.8%.
Wherein the inorganic agent proportioning of 0-1mm is: butyl dithiocarbonic acids sodium 400g/T, gasoline 140g/T, solution concentration 0.5g/L; Mixed filings with after soaking into 1 minute under inorganic agent infiltration 60 minutes or the gentle agitation, is separated with shaking table, and 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 Sn 81.33%, bronze end contains Cu 82.27%.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.
10-1 bronze end, 4-4 ashbury metal end, iron end weight ratio are about 56: 38: 6 in embodiment 2. mixed filings, use the magnetic force deironing, and are divided into three grades: 3-5mm, 1-3mm, 0-1mm.Adopt the same method of embodiment 1, separate obtaining 10-1 bronze end and contain Cu 86.7-89.5%, the 4-4 ashbury metal contains Sn 90.1-91.0%, two qualified products, its productive rate 80.8-90.2%.
