Heap Leaching Lead Zinc Ore Processing Best. Arocessing of oxide orexide ores are generally processed using hydrometallurgyhis process uses aqueous water-based solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps heap leaching, solvent extraction, and electrowinning.
Read MoreThe leaching, solvent extraction and electrowinning LX-SX-EW process is a widely used method in the production of copper from low-grade oxidized ore. Copper is the most common metal to be processed by LX-SX-EW, but the process can also be used to extract, purify and concentrate other metals, such as nickel, cobalt and zinc.

Read MoreFurther investigations into the leaching of chalcopyrite identified that leaching temperatures in excess of 70C and fine grinding of the ore to less than 0.05mm in size are key requirements to extract copper from chalcopyrite at an appreciable rate. Both requirements are not favourable for conventional heap leaching.
Read MoreBioleaching is the extraction of metals from their ores through the use of living organisms. This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several appliions within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum . Process
