Given that 40% of zinc consumed worldwide comes from recycled zinc (2) and taking the available quantity of mining resources (1,900 Mt) and growth in worldwide consumption of zinc into account (between 1.5 and 3% per year), there will be a sustainable zinc supply beyond the next century.
Nov 12, 2015· It is therefore anticipated that the choices of drinking water source in this area might be affected from those reports. However, no survey has yet been conducted in any Chinese region where lead/zinc and lead mineral resources are widely distributed, and a large population is potentially exposed to relatively high contaminant levels.
Zinc reserves. Mining resources are estimated at a level of 220 million tons of currently exploitable zinc ore reserves. Annual world consumption of zinc is at present 9.7 million tons. Since recycling accounts for about 39% of zinc consumption, zinc reserves are depleted at a yearly rate of 5.9 million tons.
