业内有关专家指出 ,目前 ,我国硝酸钾行业存在的主要问题是 :①硝酸型资源缺乏 ,目前我国仅在罗布泊附近发现有少量的硝酸盐型钾矿存在 ,但储量极其有限 ,大规模工业化开采价值不大 ;②生产规模小 ,成本高、不经济 ,国内最大生产装置的生产能力仅为 1万ｔ/ａ,而世界转化法生产 Experts in the industry pointed out that at present, the main problems in the potassium nitrate industry in China are: 1 The lack of nitric acid resources. At present, only a small amount of nitrate-type potassium ore is found near Lop Nur in China, but the reserves are extremely limited, and large-scale industrial exploitation is worth Small; 2 small-scale production, high cost, uneconomical, the production capacity of the country’s largest production plant is only 10,000 t / a, and the world’s conversion method production
