凡口铅锌矿位于广东省仁化县内,矿山资源丰富、品位高,并伴生有银等多种可供综合回收利用的贵重金属及稀散元素,经过二十来年的辛勤建设,已初步形成日处理3000吨原矿、年产铅锌精矿金属含量12万吨的生产能力和技术水平较高的地下开采矿山。1986年日处理原矿2919吨,生产铅锌精矿金属含量9.54万吨。至1986年底止已为国家生产铅锌精矿金属量100多万吨。
Fankou lead-zinc mine is located in Renhua County, Guangdong Province. It is rich in natural resources and high-grade mines, and is accompanied by silver and other valuable metals and rare-earth elements for comprehensive recycling. After 20 years of hard work, Japan processing 3,000 tons of ore, lead-zinc concentrate with an annual output of 120,000 tons of metal content and high technological level of underground mining. In 1986, 2,919 tons of ore were processed daily, and the metal content of lead-zinc concentrate was 95,400 tons. By the end of 1986, it had produced over 1 million tons of lead, zinc concentrate for the country.
