Heap leaching (HL) is a flexible and economic mineral processing method, commonly used to extract gold from low-grade gold ores. In this process, ore is firstly crushed to fine particles. In this process, ore is firstly crushed to fine particles.
Bioleaching 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 applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt.

Zinc pressure leaching (ZPL) treats zinc concentrate directly in the autoclave where specific temperature and oxygen partial pressure is given to leach zinc and generates zinc sulfate solution while sulfur, lead and iron remain in the residue (leaching residue).
Alkali-leaching and acid-leaching were proposed for the dephosphorization of Changde iron ore, which contains an average of 1.12% for phosphorus content. Sodium hydroxide, sulfuriced, hydrochloric ...
HCl is the most appropriate leaching agent for the dephosphorization of high phosphorus oolitic haemaite. • The dephosphorization can reach 90% with less than 0.18% iron loss under the optimum leaching conditions.
Acid leaching is the most efficient method for removal of phosphorus from iron ore. Among the tested acids, sulfuric acid is the most effective for this purpose. The leaching time is low (~20 minutes) and the iron loss is negligible (less than 0.25%).
