Nickel Heap Leaching Brazilian Nickel PLC

Heap Leaching is an ancient process; leaching metals out of ore goes back nearly 500 years. Mines in Hungary recycled copper-bearing solutions through waste heaps in the 1550s, Spanish miners percolated acid solutions through large heaps of oxide copper ore on the banks of the Rio Tinto in 1752 and one of the classical methods for the manufacture of copperas (iron sulphate) was to heap up iron

Heap leaching Wikipedia

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the

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
