Platinum gets its name from platina, meaning "little silver," because the Spaniards considered it an unwanted impurity in silver mining operations in Colombia. For the most part, PGMs are found together in ores. Ultramafic and mafic igneous rocks contain high levels of platinum group metals, the granites contain a low percentage of the metals.

The evaluation of agitated tank leaching verses CIP and CIL circuits is not as complex as the heap leach-agitated tank leach analysis. CIP and CIL circuits generally have lower capital and operating costs for gold ore bodies than agitated tank leach circuits. Silver ore bodies show better economics with agitated tank leach-Merrill Crowe circuits.
