Abstract
The invention provides a method for removing impurities from copper cuttings and recycling tin bronze. The method is characterized by comprising the steps of removing iron scale through magnets, removing mud and oil by baking and removing aluminum and silicon by smelting. The method has the advantages of simple operation, low cost and high metal recovery rate.
Description
Technical field
The present invention relates to a kind of metal removal of impurities treatment process, particularly a kind of copper scale removal of impurities, reclaim the tinbronze method.
Background technology
Metal adds in the tinbronze bits that produce man-hour and contains unavoidably the impurity such as iron, aluminium, silicon, sand, greasy dirt, in order to recycle tinbronze wherein, must control its foreign matter content before it is carried out melting and in fusion process, but yet there are no desirable removal of impurities treatment process in prior art.
Summary of the invention
The purpose of this invention is to provide a kind of simple to operately, cost is low, the copper scale removal of impurities that metal recovery rate is high, reclaims the tinbronze method.
For achieving the above object, the concrete treatment process of the present invention's employing is as follows:
1, magnet scrap iron removing: utilize electro-magnet or permanent magnet repeatedly the iron filings in the tinbronze bits to be absorbed.
2, baking desilt, oil: will be after the copper scale water after above-mentioned absorption iron filings be rinsed well, be placed in be baked at 200 ℃～250 ℃ temperature do not smolder till.
3, melting removes aluminium, silicon: the smelting furnace that the copper scale after above-mentioned baking is placed in 200 ℃～250 ℃ of preheatings, be warming up to 1050 ℃～1085 ℃ lower fast meltings 1～1.2 hour, add respectively the reductor of copper scale liquation weight 0.3%～0.6%, 3%～5% refining agent in fusion process, remove into the tinbronze that namely gets after the aluminium, silicon resultant double salt of piece floating after removal of impurities.
The above treatment process that the present invention adopts, simple to operate, cost is low, and metal recovery rate is high.
Embodiment
1, utilize electro-magnet or permanent magnet repeatedly the iron filings in the tinbronze bits to be absorbed.
2, will be after the copper scale water after above-mentioned absorption iron filings be rinsed well, be placed in be baked at 200 ℃～250 ℃ temperature do not smolder till, remove silt particle and greasy dirt in copper scale.
3, the copper scale after above-mentioned baking is placed in the smelting furnace of 200 ℃～250 ℃ of preheatings, be warming up to 1050 ℃～1085 ℃ lower fast meltings 1～1.2 hour, add respectively the reductor ferric oxide of copper scale liquation weight 0.3%～0.6%, 3%～5% refining agent salt or sodium carbonate in fusion process, the present embodiment is selected sodium carbonate, the high-melting-point such as aluminium, silicon, short grained impurity and refining agent effect generate the double salt of low melting point, make it to be gathered into piece floating, remove into the tinbronze that namely gets after the aluminium, silicon resultant double salt of piece floating after removal of impurities.
Claims (1)
