Radon is a very rare and dispersed element with a content of only 10 -7 % in the earth's crust. Mainly found in molybdenum ore. Re 2 O 7 which can be obtained from the flue dust of smelting molybdenum ore. Then KCl is added and then reduced by hydrogen. Generally, the content of cerium in the molybdenum concentrate is between 0.001% and 0.031%. But porphyry copper molybdenum concentrates containing rhenium mine elect up to 0.16%. The main raw material for the production of antimony is a by-product of the molybdenum smelting process When some of the copper, platinum group ore, niobium ore and even flash smelting zinc dust and slag in the ore processing waste and low grade molybdenite, rhenium can be recovered. The total production of the world's plutonium in 1978 and 1979 was 7210 and 7260 kg, respectively. The Federal Republic of Germany, Chile, Canada and the former Soviet Union are major producers of plutonium. First extract pure rhenium is extracted rhenium compound, rhenium powder is then obtained by reduction, or an aqueous solution of hydrogen by electrolysis, and then the processing timber Powder Metallurgy Method. As the name implies, it refers to some warehouse equipment used to transport and transfer goods in some small and medium-sized warehouses, ports, docks and other places of production enterprises with large space and high transferability.
