Among the 16 kinds of mineral resources whose identified resource reserves are less than 50%, many of them are currently very tight supply of minerals such as coal, iron, bauxite, and diamonds. Among the 9 minerals whose utilization of resources reserves is between 50% and 70%, mineral resources with relatively abundant resources, such as lead, molybdenum, phosphorus, cement limestone, stone, etc., and copper, cobalt, Relatively short of minerals such as silver. Among the 19 minerals with more than 70% utilization of resource reserves identified, the vast majority are advantageous mineral resources with relatively abundant resources, such as tungsten, tin, antimony, magnesite, fluorite, etc.; only petroleum, chromite and Nickel mines are short of 4 mineral resources. The utilization of identified resource reserves of minerals such as petroleum, fluorite, barite, graphite, and asbestos is more than 90%, and there is almost no reserve base for new mines.
Experts of the research group pointed out that China’s traditional advantageous minerals have basically reached the mining areas and resource reserves without new mines, and the overall service period for identifying resource reserves is about 10 years. At the same time, the shortage of mineral resources identified by the shortage of mineral reserves is in stark contrast to the severe supply and demand situation. At present, the degree of utilization of resource reserves identified by major minerals in China is contrary to the principles and results of resource allocation in the market. Overall, there is a relatively low level of utilization of scarce minerals and a relatively high degree of utilization of advantageous minerals. The over-strength development of advantageous resources due to short-term interests has led to excessive utilization of some advantageous mineral resources reserves, serious shortage of reserve resources, and precariousness of resource advantages.
from Japan as main raw material. It matches with multiple auxiliary materials with
various uses. Skeleton uses the superior glass fiber cord imported from japan. Tooth
face of the belt adopts nylon 66 high spandex for protection.
Synchronous belt drive is a novel drive mode that utilizes pulley gear meshing to
transfer motive power. It has accurate synchronous drive function. It needs no
lubrication without slip differential nor pollution and with little noise. Drive efficiency
reaches to 0.98. Speed ratio range can fulfill 1:10. Allowable linear speed can attain
50m/s. Drive efficiency ranges from several hundred watts to several kilowatts. It
suits multi-axial drive. It features as fine dynamic flex resistance, good anti-cracking
properties, superior ozone-proof performanca, sound heat-resistance and wearability etc.
Nearly half of China’s mineral resources have not been utilized
According to the information provided by the research group of the Research Report on the Sustainable Development of China's Land and Natural Resources, China has found that the degree of utilization of mineral resources reserves is relatively low. Of the 45 major minerals, only 19 were found to occupy 70% or more of the reserves, 90% were between 50% and 70%, and 17 were below 50%. The average occupancy of identified resource reserves for the 45 major minerals is only 57.86%, which means that nearly half of them are not used.
