Among free-milling gold ores placer gold is a special case, as there is no pre-treatment required for gold extraction. Gold can be extracted from placer ores using physical separation techniques, particularly through gravity treatment. In modern practice, concentrators use centrifugal force in order to liberate finer gold particles.

In assessing the economic benefit of the extra processing that needs to be done to improve recovery from refractory or partially refractory ores, it is always important to consider the incremental improvement in gold recovery versus standard grinding and cyanidation, and the incremental increase in costs to achieve this improvement.
Note the reduction in milling costs through the use of the new flowsheet which includes an 8-cell "Sub-A" Flotation Machine. These ten mines will make money even if gold price falls Oct 17, 2018· These Top 10 lowest cost gold mines are all below all-in-sustaining costs (AISC) $550/oz level and will prove profitable even if the price falls 50%.
From the framework provided by La Brooy et al. (1994), there are three main classification categories for gold ores: free-milling, refractory, and complex. Free-milling gold ores are defined as an ore from which standard cyanidation (which takes about 20-30 hours) can extract more than 90 % of the gold, under the condition that the ore size is ...
