The degree to which each of these factors is relevant in the ore response to cyanidation determines its classification, and thus the processing strategy for gold extraction. Free-Milling Ores The complete definition of a free-milling ore is ore sized 80 % 75 m from which cyanidation can extract 90 % of the gold, and has not sustained high reagent consumption (John. O. Marsden, 2006).

The extraction of ore from underground or surface mines is but one stage in a complicated and time-consuming process of producing minerals. A mine is born through exploration and mine development. This is followed by mining and beneficiation, and ends with mine closure and rehabilitation.
