NORD资源公司最近宣布,该公司在巴布亚新几内亚拉穆河的铬-钴-镍矿床探明一三层地表红土镍矿,矿化物储量约有2亿2千5百万吨。上层厚3米,估计含有1亿零7百万吨砂粘土,铬铁矿原矿品位9%,从上层回收的铬铁矿精矿可生产高碳铬铁。在高铬铁矿带下面有一层2.7米厚的褐铁矿红土镍矿,拥有8
NORD Resources recently announced that it has identified a third layer of surface lateritic nickel ore at a chromium-cobalt-nickel deposit in the Lamu River, Papua New Guinea, with approximately 250 million tonnes of mineral reserves. The upper 3 m thick is estimated to contain 107 million tonnes of sand clay and 9% chromite ore grade. Chromite concentrate recovered from the upper level produces high carbon ferrochrome. Below the high-chromite belt is a layer of limonite nickel ore, 2.7 meters thick, with 8
