Gold/silver base metal concentrate deportment. Smelters typically pay >95% (Au) and 90% (Ag) in copper and lead concentrates, but will only pay 60-70% (maximum, depending on degree of Pb/Zn smelter integration) for gold and silver in zinc concentrates. Cost drivers are also important in flowsheet selection, and are summarised in Table 3.

important lithium ore mineral. A typical run of mine ore can contain 1-2% Li 2 O, while a typical spodumene concentrate suitable for lithium carbonate production contains 6-7% Li 2 O (75% - 87% spodumene). Higher grade concentrates with 7.6% Li 2 O and low iron content are used in ceramics and more demanding industries.

Gold ore may be transformed to concentrates for one of several reasons. If the ore is refractory (not free-milling) and the capex of a pressure oxidation (POX) or (bio-oxidation) BIOX plant cannot be justified, a mine's only recourse may be the production of a concentrate. Even free-milling ore may be channelled to a concentrate stream if ...
