Extracting copper from acid drainage
We recycle over 1,000 tons of copper from acid drainage each year and purify and treat over 20,000 tons of waste water per day.
-
Circulation of industrial water
The recycling rate of industrial water is over 92%, and the weakly saving amount is equivalent to that of a West Lake.
-
Heap leaching of waste ores
We established the first heap leaching-extraction-electrowining plant in China, which can recover more than 1,000 tons of cooper each year.
-
Producing acid from smelting off-gas
We established China's largest plant that produces acid form smelting off-gas. The total utilization rate of sulfur is over 97%, which reaches the advanced level in the world.
-
Extracting copper from slags
Recovery of more than 1000 tons of copper from waste water each year, and more than 20000 tons of waste water per day
-
Generating power from waste hea
We recycle residual heat from smelting off-gas, and in this way, we can generate more than 200 million kW•h electricity each year, which could provide year-round power for a town with a population of more than 500,000.
