引言我国的土壤严重缺钾,特别是南方地区,已经严重限制了我国农业生产的发展。我国的钾肥需求量很大,但水溶性钾盐资源却很少的,因此开发非水溶性价矿资源,势在必行。如何拓宽钾肥供应渠道就成为了向迫切任务。本研究选用自制的碱性无机物活化剂QN,在不温度、时间、QN用量和加水量条件下,对钾长石进行活化处理。对累积钾浸提量影响的主次顺序为QN用量,温度,加水量和恒温时间,最优组合为200℃
Introduction The soil of our country has a serious shortage of potassium, especially in the south, which has severely restricted the development of agricultural production in our country. There is a great demand for potash fertilizer in our country, but there are few water-soluble potash resources. Therefore, it is imperative to develop non-water-soluble ore resources. How to broaden the supply of potash has become an urgent task. In this study, homemade alkaline inorganic activator QN was used to activate K-feldspar without temperature, time, QN dosage and water addition. The order of primary and secondary factors affecting the cumulative potassium extraction was QN dosage, temperature, water addition and incubation time, the optimal combination was 200 ℃
