How to make sponge copper Sincerely request, does anyone know how to make sponge copper, thank you

The smelting of copper sponge uses a crucible, which can process kilograms each time according to the crucible bought, the smelting time is 40 50 minutes, and 3 4 kg of lump coal is used. This kind of furnace has a simple structure, dig a pit in the ground, make a blast, and use ordinary bricks to line the furnace (you can also put bricks without bricks).

When operating, Mr. put a small amount of coal, after the formation of the primer, put in the baked crucible, after the crucible is red, then add copper powder, sprinkle a layer of carbon powder on the surface to prevent oxidation, cover it with refractory bricks, add a lump of coal around the crucible, blow 40 to 50 minutes to melt, melt into the model after melting.

High-grade sponge copper powder is a very important industrial raw material, copper powder is a reddish-brown powder, widely used in the manufacture of various copper alloys, precision casting into hearing parts, replacing copper. Technical characteristics: mature technology, reliable product quality, low consumption quota, high copper rate, low investment, low cost, large profits, high-tech, in a leading position in the country.

Technology transfer. Information is available upon request.

The resulting copper solution is pumped to the reaction column, and iron filings are added to react with it to form copper sponge.

There is a large amount of slag in our country that is used as waste, which not only pollutes the environment and wastes land, but also wastes a lot of resources. For example, there are many resources that can be used in pyrite slag, and copper is one of them. When the copper content in the slag exceeds 3, it has the highest value.

**The method of copper is: soak the slag with dilute sulfuric acid with a relative density of 8 Baumé for 2 3 hours, pump the resulting copper solution to the reaction column, and add iron filings to react with it to form sponge copper. After the sponge copper is dried into a spherical shape, it is mixed with broken glass, coke and limestone in a certain proportion, and sent to the copper smelting furnace for smelting, and a blister copper ingot containing about 80 can be obtained.

Pyrite slag can also produce ferric chloride and iron trioxide. Ferric chloride is a widely used chemical product that can be used to purify tap water and make other iron salts, pigments, pharmaceuticals, mordants and catalysts. There are also many metals in pyrite slag, which depends on the composition of pyrite slag.

The components of pyrite in different regions are different, which requires specific determination of the components in these pyrite slags, and then use different methods to do a good job in comprehensive utilization.

A sufficient amount of zinc powder is used to reduce copper sulfate, and then sulfuric acid is used to remove the impurities of zinc powder.

Sponge copper is sponge-like copper. The high-grade sponge copper can be used to refine metal copper and make wax as raw materials such as cuprous octanoate, and can also be used for die-casting.

Seeking Haila, this cotton copper manufacturer, I have a long-term wet replacement sponge copper iron powder, only the key rock has cooperation and mutual benefit is the fundamental round of bright and fast, hard to hit, the loser must be self-righteous himself, 13539018884

This method is very simple, and it uses a displacement reaction

Soak copper slag with dilute sulfuric acid for 2-3 hours, and then add iron filings to react with it, and replace copper from the solution to obtain sponge copper.

Soak it in dilute sulfuric acid with a relative density of 8 Baumé (°bé) [WaveMidu seems to be: 1] for 2 3 hours, and the resulting mixed copper solution is centrifugally pumped to the reaction column, and iron filings are added to react with it to form sponge copper.

**The method of copper is: after drying the sponge copper into a ball, it is mixed with broken glass, coke and limestone in a certain proportion, and sent to the copper smelting furnace for smelting, and a blister copper ingot containing about 80 can be obtained.

Seeking sponge copper manufacturers, I have long-term wet replacement of sponge copper iron powder, only cooperation and mutual benefit is fundamental, hard to hit, the loser must be self-righteous himself, 13539018884
