Embodiment 1
[0027] Such as figure 1 As shown in the flow chart, take a certain copper slag in Inner Mongolia, in which the iron oxide content is 64.3wt%, and the copper content is 1.8wt%. After drying, it is pulverized and ground, and passed through a 100-mesh sieve. The bituminous coal is ground and passed through a 100-mesh sieve. Sodium tetraborate is pulverized and ground and passed through a 100-mesh sieve for later use.
[0028] After the sieved copper slag, coal powder and sodium tetraborate are dried, they are fully mixed according to the mass ratio of 85:14:1 to obtain the carbon-matching copper slag powder. Spray a small amount of water to make the mixed powder have a certain viscosity, and then shape it to obtain carbon-copper slag balls. Put the carbon-copper slag balls into the reduction kiln, raise the temperature to 1150°C for 9 hours, keep the temperature for 9 hours, cool down for 6 hours, and then leave the kiln, after being crushed and sieved, the product-micro-electr...
Embodiment 2
[0030] Such as figure 1 As shown in the flow chart, take a certain copper slag in India, wherein the iron oxide content is 71.4wt%, and the copper content is 1.2wt%. After drying, it is pulverized and ground, and passed through a 100-mesh sieve. The coke powder is ground and passed through a 100-mesh sieve. Sodium tetraborate is pulverized and ground and passed through a 100-mesh sieve for later use.
[0031] After the sieved copper slag, coal powder and sodium tetraborate are dried, they are fully mixed according to the mass ratio of 60:35:5 to obtain the carbon-matched copper slag powder. Spray a small amount of water to make the mixed powder have a certain viscosity, and then shape it to obtain carbon-copper slag balls. Put the carbon-copper slag balls into the reduction furnace kiln, heat up for 6 hours to 1150 ° C for 9 hours, cool down for 6 hours, and then leave the kiln, and then sieve after crushing to obtain the product—micro-electrolytic environmental protection f...
Embodiment 3
[0033] Such as figure 1 As shown in the flow chart, take the tailings slag of a copper mine in Sichuan, wherein the iron oxide content is 58.7wt%, and the copper content is 7.4wt%. After drying, it is pulverized and ground, and passed through a 100-mesh sieve. The bituminous coal is ground and passed through a 100-mesh sieve. Sodium tetraborate is pulverized and ground and passed through a 100-mesh sieve for later use.
[0034]After drying the sieved copper slag, coal powder and sodium tetraborate, they are fully mixed according to the mass ratio of 80:19:1 to obtain carbon-matching copper slag powder. Spray a small amount of water to make the mixed powder have a certain viscosity, and then shape it to obtain carbon-copper slag balls. Put the carbon-copper slag balls into the reduction furnace kiln, heat up for 6 hours to 1150 ° C for 9 hours, cool down for 6 hours, and then leave the kiln, and then sieve after crushing to obtain the product—micro-electrolytic environmental ...
