Heap Leaching Technology—Current State, Innovations, and,

ABSTRACTHeap leaching is a well-established extractive metallurgical technology enabling the economical processing of various kinds of low-grade ores, which could not otherwise be exploited. However, despite much progress since it was first applied in recent times, the process remains limited by low recoveries and long extraction times. It is becoming increasingly clear that the choice of heap,US6312500B1 - Heap leaching of nickel containing ore,,A process is provided for heap leaching ore to recover nickel. The process is particularly effective for ores that have a tangible clay component (i.e., greater than about 10% by weight). The process includes sizing the ore (where necessary), forming pellets by contacting ore with a lixiviant and agglomerating. The pellets are formed into a heap and leached with sulfuric acid to extract the,Minerals | Special Issue : Heap Leaching: The State-of-the-Art,Caliche is a mineral exploited in northern Chile, from which iodine and Nitrate salts (saltpeter) are obtained.
