This high copper demand will cause various economic and socio-environmental challenges in the supply chain. First, many major operating copper mines will likely close down even before 2050 due to ore depletion (Table 1).Second, the development of newly discovered deposits takes longer than before due to stricter economic and socio …

As you will see if you read the page about titanium extraction, this is the only way of producing high purity metal. TiCl4 + 4Na → Ti + 4NaCl T i C l 4 + 4 N a → T i + 4 N a C l. The more reactive metal sodium releases electrons easily as it forms its ions: 4Na → 4Na+ + 4e− 4 N a → 4 N a + + 4 e −. These electrons are used to reduce ...

The rock must contain enough of the metal compound, hence enough of the metal, to be worth exploiting the ore reserve and extract the metal by physical and chemical processes. Low grade ores are usually uneconomic to mine and process, but high grade ores have a high enough metal content to be worth mining and extracting the metal.
