| 摘 要： | 老挝万象平原塔贡矿区钾盐矿产以光卤石为主,在矿区东部发育北西-南东走向的钾石盐矿层。钾石盐矿层分原生矿层和次生矿层二层矿:原生矿层分布于钾盐矿层的底部,矿层厚度变化大;次生矿层仅分布于中部ZKT10-6钾盐矿层顶部,矿层厚度大、品位高,分布面积小。由于受老挝当地能源与运输不足的制约,目前中国数家企业在万象平原进行小规模试验性开采,用光卤石生产氯化钾。经对塔贡矿区钾石盐矿层KCl资源量概略估算,可以满足当前中小规模开采。用钾石盐生产氯化钾不但工艺较简单,而且无须处理大量的氯化镁,环境污染小,可降低成本,提高企业利润。塔贡矿区钾石盐勘查围绕ZKT10-6孔以探明该区块次生钾石盐矿层;围绕LK22和LKTN2钻孔一带以查明原生矿层。

| Abstract: | The main Halosylvite commodities of Vientiane plain Tagong mining area in Laos are carnallite.Halosylvite ore bed trending NW-SE occurs in east mining area.Halosylvite ore bed consists of original ore bed and secondary deposit.Original ore bed spread out the lower part with irregular thickness.Secondary deposit only spreads out the middle part with large thickness,high grade and occupies small area.Constrained by deficiency of local energy resource and transport in Laos,presently several Chinese enterprises are carrying on small-scale trial exploration in Vientiane plain,producing KCl using carnallite.Through the summary evaluation,at present KCl resource of Halosylvite ore bed in Tagong mining area can meet the small and medium-sized mining.Producing KCl using Halosylvite has several advantages,such as simpler craft,unnecessary to deal with a lot of MgCl2,less pollution to the environment,cutting the cost and increasing profit of enterprise.Exploration around drill numbered ZKT10-6 has been done for proving up the Halosylvite ore bed in this area,and around drill numbered LK22 and LKTN2 for proving up original ore bed. |
