[image 145-7-02] Traditional methods viz – ore sieving, washing, etc. are obsolete and uneconomical. Pyro-metallurgy is highly costly and non-viable for low-grade ores. Leaching is the only process to extract metallic content from the low-grade ores. Among leaching methods — Heap leaching is most economical.
