松树脚锡矿是生产以锡为主、副产铜、钨、铋、铅等多种有色金属的中型地下矿山。建国初期,仅生产氧化矿,矿石年产量为0.65万 t,1965年松硫一期工程投产后,同时生产氧化矿和硫化矿。到70年代初,已形成了矿石年产量为66万 t 的生产能力,1972年,实际能力达74.63万 t,1988年的矿石年产量为58.13万 t。
Pinus tin mine is the production of tin-based, by-product of copper, tungsten, bismuth, lead and other non-ferrous metal medium-sized underground mines. In the early days of the founding of the People’s Republic of China, only the oxide ore was produced. The annual output of ore was 6,500 tons. After the first phase of the pine sulfur project was put into operation in 1965, both the oxide ore and the sulfide ore were produced. By the early 1970s, an annual production capacity of 660,000 tons of ore had been established. In 1972, the actual capacity reached 746,300 tons, and the annual output of ore in 1988 was 581,300 tons.
