西藏的扎仑茶卡硼镁矿,储量160万t,品位高,开采条件好。为了发展西藏经济,改变北矿南运的局面,满足西南、西北对硼的需求,西藏自治区决定投资2100万元人民币,在拉萨建硼镁矿加工厂,已于1995年初破土动工,预计1995年9月1日西藏自治区成立30周年竣工投产。 硼镁矿是提取硼和硼化合物的主要矿物,B_2O_3的理论含量为11.38％。我国硼资源比较丰富,但分布很不平衡,主要集中在辽宁,其次是湖南、河北,因此,拉萨硼镁加工厂的建立对改变我国硼矿厂的布局有重要作用。
Tibet’s Zalun Chaka Boron and Magnesium Mine, with a reserve of 1.6 million tons, is of high quality and has good mining conditions. In order to develop Tibet’s economy, change the situation of the north of the North Mine, meet the demand for boron in the southwest and northwest, and the Tibet Autonomous Region decided to invest 21 million yuan to build a boron-magnesium ore-processing plant in Lhasa. It broke ground in early 1995 and is expected to On September 1, the 30th anniversary of the establishment of the Tibet Autonomous Region was completed and put into operation. Boronite is the main mineral for extracting boron and boron compounds. The theoretical content of B_2O_3 is 11.38%. China’s boron resources are relatively abundant, but the distribution is very uneven, mainly concentrated in Liaoning, followed by Hunan, Hebei, therefore, the establishment of Lhasa boron magnesium plant has an important role in changing the layout of China’s boron ore plant.
