Abstract
The invention discloses a process method for smelting red copper by using copper concentrate. The method comprises the steps of decomposing, roasting and smelting raw materials to obtain copper matte, crushing the copper matte, decomposing the raw materials, roasting again and smelting again to finally obtain the red copper ingot with the copper content of more than or equal to 96 percent. The invention has the advantages of low investment, only 50 ten thousand yuan investment for plant construction, low cost, 50 percent reduction of the cost of red copper per ton compared with the prior smelting method, simple and convenient process, easy quality control and wide application in large, medium and small copper smelting plants.
Description
The present invention relates to a kind of processing method of smelting pure metal, particularly a kind of processing method of smelting red copper (blister copper) with copper ore concentrates (copper fine-powdery) from the smart powder of metallic ore.
Existing red copper is smelted and is adopted parting furnace, converter, and oxygenation, oiling (diesel oil) are smelted, and its shortcoming is, 1) smelting cost height, red copper smelting cost per ton is about 4000 yuan, 2) one-time investment is big, builds a smeltery and need invest more than 10,000,000 yuan at least and just can produce; 3) complex process, the production operation difficulty is big, the production quality control difficulty.
The purpose of this invention is to provide a kind of once invest little, the low and simple process for smelting red copper of technology of production cost.
The object of the present invention is achieved like this: its raw material adjunct ingredient proportioning and operation steps are as follows:
I) get the raw materials ready: contain 1000 parts of potassium permanganate 0.5-2 of (part by weight) copper ore concentrates part in the supplementary material; Ammonium chloride 0.05-0.1 part; Water 30-40 part, sawdust is an amount of, coal dust is an amount of, mixes, parked 1-2 hour, raw mix;
Ii) bakes to burn the article: at first, repave tight one deck wheat straw at the tight one deck Wingdale in roasting decomposing furnace fire grate upper berth, even spreading one deck raw mix after the compacting, thickness gets final product to cover wheat straw; Light a fire, add wind then, add raw mix and fuel gradually, make raw mix sintering slagging, this clinker increases 30-40% than copper ore concentrates copper content;
Iii) primary smelting: smelt in the part by weight adding smelting furnace by coke and clinker 1: 8～12, obtain the matte of copper content 60%;
Iv) matte fragmentation: the piece that matte is broken into Φ≤30mm;
V) medicine decomposes matte: press following component and part by weight: 1000 parts of matte; Potassium permanganate 0.5-2 part; Ammonium chloride 0.05-0.1 part; Water is an amount of, mixes and stirs 30-60 minute, obtains the matte mixture;
Vi) re-baking: the copper caking that the matte mixture sintering is become copper content 〉=85% by the method for bakes to burn the article;
Vii) secondary smelting: the part by weight of pressing coke and copper caking 1: 8～12 is smelted in smelting furnace once more, promptly obtains the copper ingot of finished product copper content 〉=96%.
The present invention has following advantage and positively effect: 1) smelting cost is low.According to the red copper that measuring and calculating is produced by the inventive method, per ton cost is about 2000 yuan, and the red copper of producing than the processing method of prior art reduces cost 50%; 2) one-time investment is little, and by explained hereafter red copper of the present invention, one-time investment can be produced for 500,000 yuan, is particularly suitable for small-sized copper smelting plant and adopts, and has found a kind of method of copper smelting easily for China; 3) technology is easy.By processing method of the present invention, adopt the secondary medicine to decompose, can accelerate the smelting process of copper greatly, both economized the energy, saving working hour again, and it is also very easy to operate.
Elaborate below in conjunction with embodiment:
The invention discloses a kind of novel process of being smelted red copper (blister copper) by copper ore concentrates (copper concentrate powder), its supplementary material proportioning and operation steps are as follows:
One, get the raw materials ready: raw material is a copper ore concentrates, and copper content 〉=15%, auxiliary material contain medicine and sawdust, coal dust and water, and medicine is used to decompose copper ore concentrates, and the effect of sawdust, coal dust is the ventilation property when increasing sintering, is convenient to sintering.Proportioning (weight ratio) is as follows: 1000 parts of copper ore concentratess; 1 part in potassium permanganate; 0.05 part of ammonium chloride; 30 parts in water, sawdust is an amount of, coal dust is an amount of, mixes, and parks 1-2 hour, promptly obtains the raw mix for sintering.
Two, roasting: at first at the tight Wingdale in roasting decomposing furnace fire grate upper berth, thickness can be 4-5cm, and the limestone block size is advisable with Φ=3-5cm, spread wheat straw one deck more in the above, the about 10cm of thickness, even spreading one deck raw mix after the compacting, thickness gets final product to cover wheat straw; Light a fire, add wind then, add raw mix and coke gradually, make raw mix sintering slagging, this clinker should increase 30-40% than copper ore concentrates copper content.
Three, smelt: add in the smelting furnace by coke and 1: 10 part by weight of clinker and smelt, obtain the matte of copper content 60%;
Four, matte fragmentation: the piece that water copper is broken into Φ≤3cm;
Five, medicine decomposes matte: medicine is added suitable quantity of water mix in the back adding matte proportioning (weight) ratio: 1000 parts of matte, and 1 part in potassium permanganate, 0.05 part of ammonium chloride mixes and stirred 45 minutes, obtains the matte mixture.
Six, re-baking: the copper caking that the matte mixture sintering is become copper content 〉=85% according to the method for bakes to burn the article;
Seven, secondary smelting: press 1: 10 part by weight of coke and copper caking and add smelting once more in the smelting furnace, promptly obtain the copper ingot of finished product copper content 〉=96%.
