Using wet phosphoric acid with a concentration of 26% to 40% as feedstock, high-purity monopotassium phosphate (MKP) is produced in a single step via a liquid-liquid extraction process. This simultaneously yields ammonium chloride potassium (which can be directly used as a compound fertilizer ingredient) and low-concentration raffinate phosphoric acid. The technology is patent-protected, and three industrial-scale units have already been constructed domestically (according to technical records), ensuring stable and reliable product quality. MKP is one of the fastest-growing premium varieties in the global water-soluble fertilizer market, with a terminal selling price significantly higher than that of ordinary phosphorus fertilizers. The comprehensive utilization of by-products further optimizes overall economic efficiency. A prerequisite for technology transfer is that the owner must possess a large-scale compound fertilizer production capacity to absorb the by-products. Deliverables include the process package, design drawings, operation manuals, training materials, and patent licensing documents, with a service cycle ranging from 3 to 18 months.

For phosphate ore resources with low grade or high impurity content, this technology employs a dihydrate process route to achieve the industrial production of wet-process phosphoric acid. Its core advantage lies in its broad adaptability to raw materials, enabling the processing of various grades and types of phosphate rock, thereby reducing reliance on high-quality ore sources. The process technology represents an advanced level in the industry, with a mature and reliable technical solution. The service model is consistent with the hemihydrate-dihydrate method, starting with the preparation of the process package, followed by basic engineering design and construction drawing design, and finally providing technical management support that includes personnel training and on-site guidance. All design documents and training materials are delivered concurrently with the project, with a standard cycle of 4 to 18 months. It is recommended that overseas owners intending to develop the phosphate chemical industry under local phosphate ore resource conditions prioritize the evaluation of this technical route.
