Introduction to the Enfei International Project


The company has constructed 12,000 engineering projects in over 30 countries and regions to date. Projects are being carried out in Pakistan, Afghanistan, India, Laos, Thailand, Myanmar, Mongolia, Vietnam, Iran, Kazakhstan, Tajikistan, Guinea, the Democratic Republic of the Congo, Egypt, Namibia, Zambia, South Africa, Liberia, Kenya, Eritrea, Algeria, Zimbabwe, Ecuador, Venezuela, Chile, Brazil, Peru, Chile, Mexico, Indonesia, Papua New Guinea, Australia, Canada, Romania, and other countries and regions.

International projects in which China Enfei is involved include the Liqin OBI Laterite Nickel Wet Smelting Project, the first modern nickel-cobalt smelter completed in Indonesia. The Congo (Gold) Kamoa-Kakula Copper Mineral Processing Project is the world's largest high-grade copper mine on a large scale. The Mirador copper mine in Ecuador is the first large-scale solid mine in Ecuador and the first major copper mine in South America built to meet Chinese standards. The Papua New Guinea Rimu nickel-cobalt project was awarded the "China Industry Awards Commendation Award". It represents the largest single investment by a Chinese-funded enterprise in overseas non-ferrous metal mining, smelting, and refining joint project ventures. The Dagongshan nickel laterite project in Myanmar represents the largest joint mining, beneficiation, and metallurgy endeavor between China and Myanmar. The project has been awarded the "Second Prize of National Science and Technology Progress" for its significant contributions to the mining industry. The Chambishi Copper Mining and Smelting Joint Project in Zambia is the first non-ferrous metal mine invested by China overseas. The Congo (Gold) Bombi Copper-cobalt Mine is a full-process copper wet smelting project with the shortest production time in Africa. The Gamsberg zinc mine in South Africa is one of the largest zinc mines in the world. The HUSAB Sulphur Acid Plant in Namibia is China's largest industrial investment project in Africa. The SK Mine Shaft Project in India is the largest overseas mixed-use development built to Chinese standards and upgraded on a large scale. The Vietnam Shengquan Copper Mining and Smelting Joint Project is the first overseas application of China's patented SKS technology. The Shandak Copper and Gold Joint Enterprise Project in Pakistan is China's first joint project on nonferrous metal mining and metallurgy overseas.
