China Wuhuan Engineering Co., Ltd. has undertaken an EPC project for phosphate mining and phosphate chemical plant development in Zambia, southern Africa. Utilizing the region's abundant phosphate resources to produce ammonium phosphate series fertilizers, this project represents a significant strategic move for Chinese chemical engineering enterprises to expand their fertilizer market presence in sub-Saharan Africa.

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.
