凡口铅锌矿是我国主要铅锌原料生产基地之一。它储量大、品位高、含有多种可供综合利用的伴生金属矿床。埋藏深,水文地质条件极为复杂,具有远景储量的大型矿山。经过二十多年的建设与生产,在不断地进行技术改造中,已成为一个初具日采、选三千吨,年产铅、锌金属量12万吨规模的技术水平较高,装备较先进的采、选联合企业。至1985年止,凡口矿已为国家生产铅锌精矿金属含量90.9万吨,银198吨,硫137万吨,
Fankou lead-zinc mine is one of the main lead-zinc raw material production bases in China. It is large reserves, high grade, with a variety of comprehensive utilization of associated metal deposits. Buried deep, extremely complex hydrogeological conditions, with long-term reserves of large-scale mines. After more than 20 years of construction and production, in the ongoing technical transformation, has become a take a day mining, selection of 3,000 tons, with an annual output of lead, zinc metal 120,000 tons scale of the higher level of technology, equipment more Advanced mining, selected joint venture. Until 1985, where the mouth mine has produced 909,000 tons of lead and zinc concentrate for the country, 198 tons of silver, 1.37 million tons of sulfur,
