老挝铝土矿开发项目介绍

Laos bauxite project introduction

铝土矿项目的矿区地处老挝南部占巴色省境内。矿区原矿储量9291万吨，净矿储量3697万吨，净矿平均Al2O3含量为40．01％。平均铝硅比（A／S）7．8，平均舍矿率654kg／m^3。矿区面积44．17平方公里、本项目远期规划建设120万t／a氧化铝厂，分二期建设。一期规模60t／a氧化铝，相应矿山的采选规模为450~470t／a、根据老挝矿业政策及当地能源供应情况，确定终产品为氧化铝。发展前景看好。

mining area is located in the southern Laos bauxite project of the province. The mining ore reserves of 92.91 million tons, net ore reserves of 36.97 million tons, net ore Al2O3 content is 40.01% on average. Average al- si ratio （A/S） is 7.8, the average mineral content is 654 kg/m^3. Mining area is 44.17 square kilometers. This pruject forward planniug and coustruction of alumina plant is 1.2 million t/a,including two phases of construction. A scale of 60 t/a aluminais for the fitst phase, corresponding mine selecting the size of 450~470 t/a. According to the Lao mining policy and local energy supply situation, the final product is alumina. The development of prospect is exciting.
