马斯巴特是菲律宾一个产金多年的老金矿.1905年在马斯巴特岛开始投产,1936年迅速发展成为菲律宾第一个最大的露天采金场,直至1941年二次世界大战爆发仍在进行生产,生产能力超过4000公吨/日,由于金价的上涨,自1941年日本占领菲律宾而导致停产后,重又于1978年恢复开采,并于1979年建立了一座日处理3500吨矿石的炭浆法提金工厂,1980年1月首次产出了第一根金锭.马斯巴特金矿位于菲律宾中部的比萨扬群岛中的马斯巴特岛东北部.矿体估计可采矿石储量为8百万吨,平均含金2.4克/吨,含银3.4克/吨.矿石是用露天采矿法开采.采场设计技术参数为:倾斜度为45°;台阶为
Masbat, a gold-bearing gold mine in the Philippines, started production on Masbate Island in 1905 and quickly became the largest open-air gold mine in the Philippines in 1936 until the outbreak of World War II in 1941 Production capacity of more than 4,000 metric tons / day, due to the rise in gold prices, after the Japanese occupation of the Philippines in 1941 led to the shutdown, again in 1978 to resume mining, and in 1979 established a daily processing of 3,500 tons of ore carbon The Fatih plant produced its first gold bullion in January 1980. The Masbat gold mine is located in the northeastern Masbat in the Pisan archipelago in the central part of the Philippines and is estimated to have an available ore reserve of 8 hundred Tons, the average gold content of 2.4 g / t, silver 3.4 g / t ore mining method is used open pit mining stope design parameters: slope of 45 °; step
