Flotation response of silver minerals is normally best at natural pH because lime tends to depress silver minerals in flotation. Use of soda ash for elevating pH is suggested as an alternative pH modifier. Alkyl dithiophosphates are used when high silver mineral selectivity is required.

May 17, 2018 Preparing the ore. 1 Silver ore is crushed into pieces, usually with 1-1.5 in (2.5-3.75 cm) diameters, to make the material porous. Approximately 3-5 lb (1.4-2.3 kg) of lime per ton of silver ore is added to create an alkaline environment. The ore must be completely oxidized so the precious metal is not confined in sulfide minerals.
