Founded in June 2005, Kunming Chuanjinnuo Chemical Co., Ltd. (hereafter CJN) is located in the beautiful Spring City - Kunming, capital city of Yunnan. It is a listed high-tech enterprise devoting to the development and production of phosphate chemicals. The company was successfully listed on the Shenzhen Stock Exchange in 2016 with stock code: 300505.

CJN has been committing to creating a model of comprehensive co-production of phosphate chemicals on basis of the idea of fully recycling phosphorus resources. After years of independent research and development, CJN has innovated in core technologies of phosphate industry, such as "Wet Process Phosphoric Acid Extraction and Purification Technology", "Phosphate Rock and Phosphoric Acid Classification and Utilization Technology", " Wet Process Purified Phosphoric Acid for Fine Phosphates", "Various Iron Phosphate Production Technologies", and achieved great results.

CJN has two production bases: Kunming manufacturing base (KMMB) and Fangchenggang manufacturing base (FCMB). KMMB produces annual 500,000 tons of feed-grade phosphates, 300,000 tons of fertilizer-grade phosphates, and 200,000 tons of other related products such as sodium Silicofluoride and iron concentrate powder. FCMB produces annual 400,000 tons of fine phosphate products, such as industrial grade phosphates, purified phosphoric acid, food grade and electronic grade phosphates, and a total of 1 million tons of by-products, such as triple superphosphate fertilizer and phosphogypsum building material.

As China increasingly advocating environmental friendly economic development, in order to actively respond to the national carbon peaking and carbon neutrality goals, and go with the stream of global new energy development, CJN is working to upgrade the phosphate industry, aiming to form an integrated new energy material industry  with the flow of “phosphate rock – wet process purified phosphoric acid - iron phosphate - lithium iron phosphate".

In the future, CJN will continue to grasp the general trend of the times, to strengthen confidence in new development pattern, and to achieve high-quality development of the enterprise.
