Current Situation Of Molybdenum Recycling And Utilization
Sep 14, 2018

With the continuous development of molybdenum industry, consumption of raw materials are more and more big, the recoverable resources less and less. In order to protect the environment, raise the utilization ratio of molybdenum resources, the developed countries began to focus on molybdenum renewable resources especially the use value of waste catalyst containing molybdenum since the mid - 1980s. In addition, molybdenum regenerated resources usually contain more molybdenum than molybdenum minerals, and the cost of extracting molybdenum and other metals from molybdenum regenerated resources is lower than that of extracting from ores. Especially energy consumption and exhaust emissions are small, so the recycling of molybdenum has become the focus of molybdenum industry.

At present, the secondary resources of molybdenum mainly come from two sources, one is the molybdenum-containing waste residue and waste liquid produced in the process of molybdenum metallurgy, the other is the waste material produced in the process of the production of molybdenum metal products and the used molybdenum-containing chemical products or materials. According to the IMOA(International Molybdenum Association), nearly 80,000 tons of molybdenum were recycled in 2011, accounting for about a quarter of the total consumption of molybdenum. Therefore, the reclaimed molybdenum resources have become an important part of the molybdenum supply chain. The International Molybdenum Association predicts that by 2020, the recovery of molybdenum will reach 110,000 tons, accounting for about 27% of the total supply of molybdenum, and by 2030, the proportion will be about 35%. About 60% of the recovered molybdenum is used to make stainless steel, while the rest is used to make alloy tool steel, superalloy, high-speed steel, cast steel and chemical catalysts.
