Permanent Minerals Co., Ltd. is a Tanzania-registered integrated mining enterprise, whollyowned by Qingdao Lianyou Graphite Technology Co., Ltd. of China. Headquarteredat Shambarai Street, Mirerani Town, Simanjiro District, Manyara Province, Tanzania, thecompany is strategically located in the heart of East Africa’s premium graphite resource belt. Building on the success of its first graphite processing plant established in Tanzania in 2019, the company launched a strategic exploration program in new mining areas in 2022 andachieved full-scale production on July 24, 2024. With a total investment of 200 million RMB(approximately 28 million USD), it now stands as Tanzania’s largest and most verticallyintegrated graphite producer.
Permanent Minerals Co., Ltd. prides itself on its “end-to-end autonomy” as a corecompetitive advantage. Its operations span six key stages: graphite mining, ore crushing, flotation purification, mechanical dewatering, high-temperature drying, and precisionscreening, forming an integrated production system from raw material to finished product. The company utilizes modular smart production lines equipped with automated control systems to ensure efficiency and product consistency. With advanced processingtechnologies, it reliably supplies graphite powders ranging from 80 mesh to -325 mesh, catering to diverse industrial applications such as new energy batteries, refractory materials, and sealing components.
The company’s products have earned global market trust through exceptional quality andreliable supply. Its clientele spans four continents—Asia, Africa, the Americas, andEurope—with key partners including new energy material manufacturers in China, steel conglomerates in India, refractory material enterprises in Iran, local industrial projects inTanzania, graphite processing specialists in the United States, and eco-technology firms across Europe.

Our main product is natural high-carbon large-flake graphite. Our production process has been refined over nearly 30 years, ensuring the best quality.
Our company has tried different types of graphite purification methods and has the capability to implement different purification schemes. However, because the graphite ore in Tanzania is of extremely high grade, we are currently using the graphite flotation process, namely crushing-grinding-flotation-drying.
We are capable of producing various types of natural flake graphite, including but not limited to: carbon content 93%-97%, particle size +50, 80, 100, -120, 150, 200, 325, etc., as well as different types of mixed positive and negative mesh sizes.
