我国钾长石资源储量大,质量好,分布广。为了适应农业需用钾肥和其它部门的需要,各地区因地制宜开展了利用钾长石制取钾盐或含钾复合肥料的试验研究,有的已取得了可喜的进展(本刊1972年第2期,1973年第1期曾有部分报道)。遵照伟大领袖毛主席关于“外国一切好的经验,好的技术,都要吸收过来,为我所用”的教导,我院组织研究室和科技情报室有关人员查阅了半个多世纪以来国外在这方面的大批文献报道,并由参与这一工作的邹润华同志执笔,初步整理了《国外从钾长石中提取钾盐和制造钾肥的研究概况》。由于查阅 China’s potassium feldspar resources have large reserves, good quality, and wide distribution. In order to adapt to the needs of agricultural potash fertilizer and other sectors, various regions have conducted experimental studies on the use of potash feldspar to prepare potash or potassium-containing compound fertilizers. Some have made gratifying progress. (No. 2 of 1972) There were some reports in the first issue of 1973.) In accordance with the guidance of the great leader Chairman Mao on “All the good experience of foreign countries, good technology must be absorbed and used for my own use”, our institute organized research institutes and relevant personnel of the Sci-Tech Intelligence Unit to inquire abroad for more than half a century. A large number of reports in the literature and written by Comrade Zou Runhua, who participated in this work, initially collated the “Overview of Research on Extraction of Potassium Salt from Potassium Feldspar and Production of Potassium Fertilizer Abroad”.
