It is understood that the current secondary copper industry in Qingyuan is mainly distributed in Shijiao and Longtang Town, and there are about tens of thousands of people engaged in this industry. In June 2008, Cai also joined this mighty army of copper smelting. Compared with those veterans who did this business after 80s and 90s, Cai, who is 365 and 438+0 years old, is just a newcomer. However, his "movement" is still quite big. First, we rented an abandoned factory building of about 600 square meters in a village in Longtang Town, dug two large ponds and two small ponds, and added some necessary equipment. In this way, a simple but decent copper sulfate factory was established.
Buy industrial copper sulfate water from outside, and then react with it with iron to replace the copper inside. Cai started his own "road to wealth" with such an indigenous method. "In the process of replacement, you will smell a sour taste and there will be a layer of water mist on the water." Cai described the process of copper smelting like this. The waste water produced after refining is directly discharged to the outside without any harmless treatment. According to statistics, from June 2008 to February this year, Cai bought more than 65,438+0,000 tons of copper sulfate water. After testing, the copper content in the soil of this copper sulfate plant is 465.145-10140.913mg/kg, which seriously exceeds the soil environmental quality standard (GB15618-/kg). Copper has seriously exceeded the standard, causing serious pollution to the soil environment.
