Extracting from low grade ores FLSmidth

Extract copper and gold from low-grade ores more efficiently. Ore deposits are becoming increasingly complex to treat and grades continue to deteriorate in known reserves. For instance approximately 15-20 per cent of the worlds current gold production involves refractory ores that must be pre-treated prior to downstream recovery by cyanidation. Ores are refractory for many reasons but commonly because

How is copper extracted from a low grade ore of it

Leaching is the process to extract pure copper from a low grade ore. Leaching is the process of extracting substances from a solid by dissolving them in a liquid in this process the ore is dissolved in liquid but not impurities. Then the copper solution is reacted with iron to get pure copper reduction process. C u2 H 2.
