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.
