  • To conserve molybdenum resources and meet increasing domestic demand, China has imposed constraints on mining and processing, and issues mandatory production plans every year. According to the mandatory production plans, the production quotas of molybdenum concentrate were 185,000 tonnes in 2010 and 200,000 tonnes in 2011. China has also restricted the amounts of molybdenum that can be exported since 2007. The first batch of export quotas for 2014 is 25,146 tonnes, accounting for 70% of the total annual quota.
