Together with his co-workers, Chen Jiayong successfully developed a process of high pressure ammonia leaching of refractory oxidized copper ore as well as the hydrometallurgical process to recover nickel and cobalt in metallic form from laterite and nickel silicate ore. This discovery contributed to the aid of foreign countries. Chen led the preparation of different kinds of composite coated powders and the production of pilot plant scales for the national defense industry. He conducted fundamental research on the gas-liquid-solid phase reactor and the separation engineering for developing effective equipment and optimum operation conditions.

With regard to China's mineral resources, Chen developed new and effective processes for the separation of vanadium from chromium, tungsten from molybdenum and iron from other valuable metals. He also developed a new solvent system for the recovery of antibiotics such as Penicillin G and Lincomycin from filtered fermentation liquor. He has been granted a number of patents for the processes he has developed.
