Currently, a pilot plant operated by the Bolivian state mining company is producing small quantities of lithium carbonate as they experiment with different modes of extraction.

一家由玻利维亚国家矿业公司经营的试验工厂最近正在利用不同的提取方法生产少量的碳酸锂。

The optimum conditions of extraction, washing, stripping, further removal of magnesium and the deposition of lithium processes were achieved during the experiments.

通过实验确定了萃取、洗涤、反萃取、深度除镁及沉锂过程的最佳条件。

With increasing number of carbon atom of alkyl group in the ionic liquid the extraction efficiency of lithium obviously increased.

锂的萃取率随离子液体中烷基碳原子数的增加而增加。

In my opinion, they want Mes Aynak to set a precedent -- to be a model for resource extraction of the one trillion dollars plus of valuable minerals like oil, copper, lithium and iron buried underneath Afghanistan.
