In November of 2010, People's Government of Hunan Province had built a strategic partnership and deep collaboration with China National Building Material Group Corporation, which is China central enterprise, directly under the State-owned Assets Supervision and Administration Commission. To speed up the process of new industrialization in Chenzhou city and promote local economic development，a strategic cooperation framework agreement on building up China's largest graphite industrial base has been signed by Mr. Xiang Lili , Mayor of Chenzhou Municipal Government and Mr. Cao Jiang-Lin, the director and president of CNBM.
Production Base—LUHE TAI MINING AREA
The ore production base of South Graphite Co., Ltd. is located in Lu He Tai mining area in Chenzhou city, Hunan Province. It’s only 50 KM from Chenzhou downtown. The mining area stretches from north-south about 20KM, and with the width of 2.15 km on average from east-west. Its total area is around 45 square kilometers. In 1985, the State Geological Bureau proved the mining reserves of 34.07 million tons of graphite, which consisted of 72.5% of total proven reserves of amorphous graphite in China.
The products in Luhe Tai mining area is high-grade mineral. Containing 80% fixed carbon on average, 92% on highest. It is well known for good quality.
According to estimation recently, the mining reserves of 25.151 million tons of coal and 12.469 million tons of graphite in the scopes which have mineral rights. Outside the scopes which have mineral rights, detailed investigation has reached 8.87 million tons of coal reserves, 5.12 million tons of graphite reserves. And forecast that the mining reserves of 16.33 million tons of coal, 9.53 million tons of graphite in the deep mining area.
Oil drilling graphite
Our oil drilling graphite powder has excellent lubrication, so can effectively reduce torque, wear and fatigue of the drilling, to extend the entire life cycle of the bit bearing. And also able to reduce the frictional resistance of the drill string, shorten the trip time; and prevent stuck, bit balling. The graphite powder can be strongly adsorbed in drilling tool and side wall, so as to improve the state of the friction between the friction pair, to play a role in reducing friction. Meanwhile, graphite powder adsorption in the side wall, the side wall microvoid can be closed, so can achieve double effects on reducing the filtration of drilling fluid and protecting reservoirs.
Fixed carbon content: 60%, 65%, 70%, 75%, 80%
Size: 45mesh,100mesh, 200mesh, 325mesh
Moisture: less than 2.5%
